A Bronze Age Quarry in Eastern Crete

Abstract

The sandstone quarry at Mochlos is one of four major quarries in eastern Crete that were worked during the New Palace Period of Minoan civilization (ca. 1700–1450 B.C.) to produce large ashlar blocks for nearby Minoan sites. At that time sandstone, or ammoudha, as it is known locally, was especially valued as a building material, partly because of its distinctive color and texture, but mainly because of the ease with which it could be cut, and the stone was used extensively for exterior façades, for walls around interior courts, and for other architectural features of the more important buildings on these sites. This article describes the quarry at Mochlos in some detail, including the quarrying techniques employed, and argues that the destination of the stone from the Mochlos quarry was the Minoan palace at Gournia. The article ends with a comparison of the four ammoudha quarries in eastern Crete.     

NEUTRON ACTIVATION ANALYSIS AT THE BRITISH MUSEUM,LONDON

Neutron activation analysis was used at the British Museum from 1978 until 2002 for provenance studies on ceramics and marble. Significant numbers of the items analysed were of high quality and value, and careful sampling was necessary to avoid damage to the object. An in‐house British Museum Standard Pottery was established and inter‐calibrated with a number of standards used by other archaeometry laboratories. The results of the projects have been published in many papers, and the databases established will be of use to future scholars interested in the ceramic groups represented. Projects on Greek and Near Eastern pottery have been undertaken. Relatively large numbers of north European medieval and post‐medieval pottery samples were analysed, as well as the tin‐glazed ceramics of Spain and Italy. Classical marble has also formed the subject of another project and a database of quarry material has been established.     

MAGNETIC SUSCEPTIBILITY VARIATIONS AT MONS CLAUDIANUS AND IN ROMAN COLUMNS: A METHOD OF PROVENANCING TO WITHIN A SINGLE QUARRY

Mons Claudianus in the Eastern Desert of Egypt was an important source of granodiorite for Roman columns. Computer contouring of 1119 magnetic susceptibility measurements at the quarry shows systematic variations, with low readings in the west of the quarry area and higher readings in the east. One hundred and seventy measurements on 62 columns of Mons Claudianus type in Rome and its environs were compared with the quarry readings, using a t-test based procedure. Some columns with distinctively low or high magnetic susceptibility could be provenanced very precisely to areas of about 700 × 700m within the 9km² of Mons Claudianus. Columns with susceptibility in the middle of the Mons Claudianus range could not be provenanced precisely. Results indicate early (first century AD) use of both west and east parts of Mons Claudianus, and contemporaneous use of several parts of the quarry, rather than systematic or sequential opening of the area. Columns found in third-century AD monuments, provenanced to the same parts of Mons Claudianus as earlier material, may indicate reuse of columns in some monuments. Magnetic susceptibility constitutes a portable and non-destructive method capable of provenancing not only to a quarry, but to specific areas within a single quarry.

Ammonite dating of latest Cretaceous mosasaurid reptiles (Squamata,Mosasauroidea) from Jordan—preliminary observations

Jagt, J.W.M., Jagt-Yazykova, E.A., Kaddumi, H.F. & Lindgren, J., April 2017. Ammonite dating of latest Cretaceous mosasaurid reptiles (Squamata, Mosasauroidea) from Jordan—preliminary observations. Alcheringa 42, 587-596. ISSN 0311-5518

Newly collected ammonoid material from the uppermost Cretaceous portion of the Muwaqqar Chalk Marl Formation exposed some 30 km southeast of the Qasr Al’Harrana area (east-central Jordan) includes medium-sized baculitids (Baculites ovatus auctorum, non Say), the sphenodiscid Libycoceras acutodorsatus (Noetling) and the pachydiscids Menuites fresvillensis (Seunes) and Pachydiscus (Pachydiscus) dossantosi (Maury). Of the two last named taxa, the former is a good marker species for the upper Maastrichtian, with records from Europe, central Chile, South India, Baluchistan (Pakistan), Australia, Madagascar and South Africa. The latter is known from the United Arab Emirates/Oman border area, from strata of (late) early to early late Maastrichtian age, as well as from more poorly constrained Maastrichtian levels in Brazil and Nigeria. A comparison with ammonoid assemblages from the Maastrichtian type area (southeast Netherlands/northeast Belgium) suggests correlation of the Muwaqqar Chalk Marl Formation with the middle/upper Maastricht Formation (Emael and Nekum members, ca 66.5–66.1 Ma) and the upper part of the coeval Kunrade Formation. However, associated ‘tegulated’ inoceramids of the Tenuipteria argentea group from the Muwaqqar Chalk Marl Formation favour equivalence with a higher level of the Maastrichtian type area, i.e., the Meerssen Member. From the upper Maastricht Formation and the equivalent upper part of the Kunrade Formation, the following mosasaur genera are currently known: Mosasaurus, Prognathodon, Plioplatecarpus and Carinodens. Interestingly, coeval strata of the Muwaqqar Chalk Marl Formation in east-central Jordan have yielded remains of a largely comparable suite comprising Prognathodon, Mosasaurus, Carinodens and an unnamed, highly derived plioplatecarpine.

Approaching the Hatch Jasper Quarry From a Technological Perspective: A Study of Prehistoric Stone Tool Production in Central Pennsylvania

Abstract

Mitigation of the Hatch jasper quarry, a “prospect site” in Central Pennsylvania, has enabled the reconstruction of a local system of stone tool acquisition and production. Artifacts from the quarry and the nearby Houserville habitation complex were analyzed using an attribute-based stage typology. This technological approach permitted the separation of geofacts from artifacts, and revealed evidence suggesting that Houserville knappers obtained tool stone from the quarry. Attention was also given to the study of how systematic heat treatment was used to enhance the flaking characteristics of the Hatch quarry jasper. This research highlights the benefits that a technological analysis of flake artifacts, in addition to finished tools, can provide for understanding stone tool production at quarry localities.     

Quarrying and Production of Milling,Implements at Antelope Hill,Arizona

Abstract

To process mesquite, maize, and other substances, aboriginal groups living in the Lower Colorado-Lower Gila rivers region of SW North America used characteristic milling equipment: squared, flat-faced, convex-based metates (lower grindstones) with elongated manos (upper grindstones) and large wooden mortars with long, cylindrical stone pestles. Andesite and sandstone bedrock outcrops where stone was quarried and milling implements produced have been located. The archaeological deposits at the quarries have not been masked by the debris of later quarrying for rotary mills or building blocks, and thus the quarry sites offer an opportunity to study the production of ancient forms of milling implements, and provide insights into the organization of an ancient stone technology. Antelope Hill, a large arkosic sandstone quarry on the Lower Gila River in Arizona is presented as an example of a widespread phenomenon in the region. Analysis of quarry debris in the field and laboratory, experimental replication, and ethnographic and historical data, combined, have resulted in an understanding of this aspect of aboriginal technology.     

On the Horn-shaped Head-Dresses of the 13th, 14th,and 15th Centuries

Abstract

The excavation of the only Cistercian abbey firmly established on the Isle of Man produced clear evidence of its church plan, its various modifications and its modest architectural pretensions. The burials contained some grave goods and displayed early methods of burial. An unexpected feature was a chapel attached to the east end of the north transept north chapel.     

Ancient ‘Black’ Decorative Stones and the Ephesian Origin of Sculptural bigio antico

Isotopic, EPR and petrographic studies aimed at establishing the provenance of sculptural bigio antico are reported, including 18 possible quarry sites and 21 ancient sculptures. The results demonstrate that the Belevi quarry, north‐east of Ephesos, above the more famous white marble quarry, was the major source of this marble. Nineteen artefacts belong to Belevi, whereas the precise origin of the remaining two is unknown, but must probably be found within the same area. The peculiar distribution of δ¹³C values both for Belevi and artefacts was crucial for inferring the correct provenance, subsequently confirmed by additional analytical and petrographic data.     

Hydrological monitoring of an alluviated landscape in the lower Great Ouse valley at Over,Cambridgeshire: the quarry restoration phase

Abstract

This paper sets out the results of the last phase of the hydrological monitoring programme conducted at the Hanson Over quarry in Cambridgeshire, during the first full year (March 2004 to March 2005) in which the area of the first phase of gravel extraction was reinstated as reed beds under the management of the Royal Society for the Protection of Birds. It follows on from the studies of the pre-extraction and extraction phases, both published previously in Environmental Archaeology (French et al. 1999; French 2004). It is reassuring to report that the groundwater table in the formerly quarried area and the landscape immediately upstream and downstream has ostensibly been restored to pre-extraction levels, along with a return to previous pH, conductivity, redox and dissolved oxygen values in the groundwater system. Significantly, the continuing gradual fall in groundwater levels observed beyond 500 m from the quarry face for a distance of at least 1·5 km was seen to be arrested, although these had not quite recovered to pre-extraction levels downstream to the northeast. In addition, the soil moisture within the alluvial overburden and the buried palaeosol has also almost returned to pre-extraction levels. This indicates that the clay bunding of the formerly quarried areas acts as an effective barrier against further water abstraction, both inside and outside the sealed area, and allows the natural aquifer to begin to return to its previous levels of influence.

The study dramatically indicates that both the mineral operator, drainage authority and archaeological curator need to collaborate from the outset of any quarrying operation to ensure the continuing maintenance of the groundwater and soil moisture system regardless of how well the combined gravel and water abstraction processes are conducted, and how successful the post-quarry conservation is. As every site's landscape dynamics contribute to its individual hydrological setting, each case is different and requires tailored monitoring programmes to protect the archaeological and palaeo-environmental record from the adverse effects of water abstraction associated with development schemes.     

Long-term performance evaluation of an earthen grouting mortar: the Nuraghic complex of Genna Maria,Sardinia

Abstract

This paper presents a critical assessment of the long-term performance of an earth-based material employed nine years ago in conservation work on a building of massive, Cyclopean-style construction at the Genna Maria Nuraghic complex in central-southern Sardinia (Italy). The material was used for filling the large gaps between stones in the masonry walls to create a barrier to ingress of water into the masonry walls. In situ observations and laboratory analyses were conducted on samples of the grouting material to assess its condition after nine years.     

Late Silurian pentameride brachiopods from Yass and Molong,New South Wales

The five known species of pentameride brachiopods from the Yass Syncline Ludlow (LateSilurian) succession, belonging to the superfamilies Pentameroidea, Gypiduloidea and Clorindoidea, are fully revised; no new species are recognised. The pentameroids Conchidium sp. cf. hospes and Aliconchidium yassi are confined to the Bowspring Limestone Member (Silverdale Formation). The gypiduloid Ascanigypa glabra and externally homeomorphic clorindoids Barrandina wilkinsoni and Clorinda minor replace them in the overlying Barrandella Shale Member, the last two extending into the Yarwood Siltstone Member (Black Bog Shale). Clorinda minor is also possibly present in the Rainbow Hill Member (Rosebank Shale). All except C. minor are uncommon to rare components of the Yass brachiopod fauna. Clorinda molongensis, a species of uncertain mid- to late Silurian age from the Molong Limestone, is also revised. Aliconchidium and Barrandina are known only from Yass, whereas Clorinda is cosmopolitan. Conchidium alsois widespread, but C. hospes is a species from the Prague Basin probably also known from the Urals and the Tien Shan. Ascanigypa is another Prague Basin taxon, recently recognised in Arctic Canada.     

ARAMAIC BASALT STATUES FROM TELL HALAF,SYRIA: LOCATING THE ANCIENT QUARRIES

Tell Halaf is the locality of the ancient Aramaic city of Guzāna (c. 1000–800 bc ) in Syria. The statues of Tell Halaf were made from monolithic basalt blocks, comprising massive as well as amygdaloidal types. However, the exact location of the original quarries was as yet unknown. Reconnaissance mapping and sampling concentrated on the four basaltic centres in the vicinity of Tell Halaf, covering both south‐eastern Turkey and north‐eastern Syria. In addition, basaltic artefacts from the two archaeological sites of Tell Beydar (c. 2700–2300 bc ) and Djebelet el Beda (c. 2600–2350 bc ) were investigated. All basalt samples were analysed for their bulk rock major and trace element compositions by X‐ray fluorescence, ICP–MS analysis and the mineral chemistry of individual minerals by combined electron microprobe analysis and laser‐ablation ICP–MS. The data show that basalt works of art from all three archaeological sites were derived from the Syrian basalt plateau of Ard esh‐Sheikh, approximately 57 km south of Tell Halaf. Accordingly, this basalt quarry was actively exploited over a considerable time span of c. 1900 years. This study demonstrates that petrographic and geochemical investigations of basalt, combined with electron microprobe and laser‐ablation ICP–MS analysis of minerals, are powerful tools to discriminate between possible sources of raw materials, especially if isotopic data yield unsatisfying results.     

A Multidisciplinary Approach for the Archaeometric Study of Pozzolanic Aggregate in Roman Mortars: The Case of Villa dei Quintili (Rome,Italy)

This contribution focuses on the study of historical mortars from a Roman archaeological site known as Villa dei Quintili, a monumental villa located in the south‐eastern part of Rome (Italy). The study was carried out on 38 mortar samples, collected from several edifices within the complex. A multi‐analytical approach, including polarized optical microscopy, scanning electron microscopy coupled with energy‐dispersive system and laser ablation inductively coupled plasma mass spectrometry, was used to analyse the pozzolanic material used for the preparation of mortars. Data obtained on both major and trace elements were compared with the compositions of Pozzolana Rossa, Pozzolana Nera and Pozzolanella samples from the Alban Hills volcanic district, collected from a historic quarry nearby, as well as with literature data. The results of such a multidisciplinary approach allowed us to recognize the use of all three pozzolan types for the aggregate fraction of examined mortars from the Villa dei Quintili.     

The appearance and disappearance of Birket El-Kamar,Jaffa, Israel

ABSTRACT

The harbor of Jaffa is one of the oldest in the land of Israel and was a significant entry from the sea for the last 4000 years, from the Middle Bronze Age to the twentieth century. Birket el-Kamar was a sandy bay in the coastal strip south of modern Jaffa harbor that had been part of the harbor during various past periods, but no longer exists. Its name, meaning ‘the Moon Pool’, occurs in historical archival documents, mainly maps, from the nineteenth century to the first half of the twentieth century. This study focuses on the changing outlines of Birket el-Kamar during the last 800 years, based on recently revealed archaeological remains, and documentary evidence. It seems that in addition to the natural processes, the Ottoman fortress that was built on the natural sand strip connecting the rocks in the sea with the coast, also affected the on-going processes, through which the inner port, the central port and the north anchorage suffered higher erosion rates and the shoreline retreated eastward.     

Determining the provenance of black limestone artifacts using petrography,isotopes and EPR techniques: the case of the monument of Bocco

This paper investigates the provenance of the black limestone of the monument known as Bocco, named after the king of Mauretania who presented Silla with this work as a sign of his submission to the power of Rome. A multi-method approach, comprising petrographic observations, carbon and oxygen isotope composition and electron paramagnetic resonance (EPR) spectra characteristics, was used for this purpose. The monument is part of a reconstruction of a rectangular base (approx. 8 × 2 m) which is likely to have served as the base for a bronze statuary group and is currently composed of six blocks of limestone whose exterior is engraved with a fine frieze. The results of the different analyses were compared with the data of a published database of the most important black limestone quarries exploited during Roman times in the Mediterranean area. The petrographic and physico-chemical parameters did not prove to be very effective in determining the provenance of the black limestone of Bocco; the isotopes result even raised some uncertainty as to whether all six blocks came from the same quarry, though this doubt was dispelled by the EPR data and, above all, by the evident petrographic similarity between them. Differences in the isotopic composition of the various blocks may be due to an in situ rock alteration process caused by interaction with an aqueous fluid. It was, however, impossible to determine with certainty the origin of the material of the stone artifact using the database available; it is possible that the black limestone of Bocco came from an ancient quarry that is likely to be located in north western Africa but has not yet been uncovered. An alternative hypothesis, according to which the limestone used for the monument of Bocco came from the ancient quarry of Ain el Ksir, one of the Tunisian quarries present in the database, is also discussed.     

Flotation versus dry sieving archaeobotanical remains: A case history from the Middle Horizon southern coast of Peru

Abstract

During excavations at the site of Casa Vieja located in the Peruvian coastal desert, archaeological plant remains were systematically collected to assess whether it is more productive and informative to sieve sandy sediments in dry environments or to process such samples by water flotation, a persistent methodological concern. At Casa Vieja, dual subsamples were collected and analyzed using both of these procedures. For dry, sandy sediment conditions, each processing strategy was found to yield a different view of the botanical remains. Dry sieving recovers more of the larger plant specimens whereas water flotation yields more of the smaller-sized material. These results should be incorporated into archaeological research designs in the future, especially for desert environments.     

Ordovician (Bendigonian,Darriwilian to Gisbornian) faunas from the northern Molong Volcanic Belt of central New South Wales

Diverse shallow water assemblages dominated by brachiopods, molluscs, sponges and stromatoporoids, and a tabulate coral, in the Wahringa Limestone Member (Darriwilian-Gisbornian), and Yuranigh Limestone Member (Gisbornian, or early Late Ordovician) of the Fairbridge Volcanics, are documented from the northern Molong Volcanic Belt in central N.S.W. New species described include Billingsaria spissa, Shlyginia printhiensis and Sowerbyites? wahringaensis. Elements of the Wahringa Limestone Member assemblage such as Labechia banksi, Labechiella regularis, and Maclurites cf. M. florentinensis are biogeographically significant in displaying strong similarities with contemporaneous Tasmanian faunas. The brachiopods Ishimia and Shlyginia from the Yuranigh Limestone Member are recognised for the first time outside Kazakhstan and Sibumasu. The presence of the brachiopod Anoptambonites in allochthonous limestone breccia within the lower Fairbridge Volcanics provides evidence of a regionally significant hiatus of 10–15 Ma duration separating this unit from the underlying Hensleigh Siltstone, of Early Ordovician (Bendigonian) age. The sponge Archaeoscyphia?, from allochthonous limestones in the latter formation, is the oldest macrofossil yet described from the Lachlan Fold Belt in central N.S.W.
