Limestone Houses in Central Kansas

Immediately after the Civil War, the Plains Border in central Kansas offered the westering peasant a set of new challenges. In an almost treeless environment, a suitable building material was a prominent prerequisite for permanent settlement. Its almost universal availability together with its conveniently uniform thickness and initial softness made the Fencepost limestone a suitable substitute for wood. Its dimensions, color and texture impart to the entire cultural landscape an element of uniformity anda unique folk character. Houses and barns, churches and stores, even curbstones and fences display the character of this important building stone. Quarrying and building were accomplished by laymen and their methods, employing uncomplicated tools, resulted in a straightforward vernacular architecture. While several design types appeared, ethnic affinity was expressed in the treatment of appurtenances rather than by any overt distinction of design. The use of stone represents the influence of material availability rather than ethnic experience. Rail service brought lumber into competition with stone and after the 1920s the use of stone was discontinued. The veneration of old things, current in the country, has placed the stone forms remaining on the threshold of a new popularity and appears to assure their survival     

The partial re-erection of the Temple of Trajan at Pergamon in Turkey: A German Archaeological Institute project

Abstract

The re-erected Temple of Trajan, one of the most prominent monumental structures visible today at Pergamon, is based on the principles of anastylosis. The first task of the team, working under the auspices of the German Archaeological Institute, was the complete documentation of all existing architectural elements. When the preserved fragments yielded sufficient information, these pieces were joined together and restored to their original position in the Trajaneum. If necessary, missing parts of the temple were added using an artificial stone formed from a mixture of crushed marble and white cement, a material that is clearly distinguishable from the original natural stone. This re-erection preserves the integrity of the temple, while simultaneously enabling the visitor to imagine the original splendour of this monumental building.     

MICROCHEMICAL CHARACTERIZATION OF BUILDING STONE FROM SEVILLE CATHEDRAL,SPAIN

Enrichment diagrams for trace elements have been proposed as a useful and straightforward procedure to identify ores and stones. The identification of the diverse stone of the exterior of the Cathedral of Seville has been achieved by this means. Fourteen trace elements have been analysed, from both quarry and building material samples, using atomic absorption and flame emission spectrometry in order to apply enrichment diagrams for identification purposes.     

壳聚糖/二氧化硅复合仿生膜对 碳酸盐石材的保护作用

为探讨壳聚糖/二氧化硅复合仿生膜对碳酸盐石材的保护作用,采用仿生合成技术,以十六烷基三甲基溴化铵为有机模板,能过壳聚糖调控二氧化硅颗粒的生长,在碳酸盐石材表面仿生合成得到了一层壳聚糖/二氧化硅复合保护膜,对其基本性能进行了检测评价,并利用衰减全反射红外光谱和场发射环境扫描电子显微镜表征了膜的结构形貌。实验结果表明,该膜具有优良的耐酸、耐污性能,提高了膜层的抗冻融性和耐热老化性能,并保留了石材原有的吸水性和透气性。壳聚糖/二氧化硅复合膜改善了单一二氧化硅膜的开裂问题,且该保护膜与石材基体结合紧密、膜层薄,小影响石材外脱,是一种良好的碳酸盐石材保护材料。     

Reconstruction of the Rib Vaults of the Hypostyle Hall in the Maniace Castle of Siracusa After the 1693 Earthquake

Built in the first half of the 13th century on behalf of the Emperor Frederick II, the Maniace Castle of Siracusa focuses its enigma in the hypostyle hall (which was composed of 25 quadripartite rib vaults) and the design criteria adopted for its implementation. Recent research and a careful rereading of the documentary “restoration project” after the earthquake of 1693 have offered new tools to understand the construction techniques and building procedures for the entire organism. It has been possible to demonstrate that the different material (white limestone and volcanic stone) used for the vaults is, in fact, a product of reconstruction. The constructive node, which historiography has taken for granted, is now crucial—the documentary evidence of the restoration after the earthquake compared with the materials found in situ provide interpretive keys to decode genesis and procedures of the huge structure built five centuries before.     

石质文物表面墨迹的保护作用

在许多不可移动石质文物,尤其是石刻文字表面,因历代文人墨客的拓片留下了大量墨迹。这些墨迹是否对文物本体岩石有害?一直是保护工作者希望了解的问题之一。为此本研究开展了一系列调研和实验研究。通过对各地保存较完好的石刻表面的观察,可以发现石刻表面残留的墨迹具有某种保护作用;对模拟样块的SO2腐蚀实验结果表明,岩石表面的墨迹具有一定的阻止空气中腐蚀性气体侵蚀岩石的作用;盐迁移破坏实验也发现墨迹在某种程度上具有减小可溶盐结晶破坏岩石的作用。吸水率实验和电镜观察等结果显示,墨迹缓解岩石风化的机理主要是墨迹对岩石微裂隙具有填充和加固作用,使岩石的吸水系数降低,部分阻挡了可溶盐的入侵和聚集结晶。     

Raw material quality and Oldowan hominin toolstone preferences: evidence from Kanjera South,Kenya

The role of raw material quality in Oldowan technology has not been fully explored. There are numerous studies suggesting Oldowan hominins preferred certain types of stone for artifact manufacture. Previous studies of the artifact assemblage from the early Pliocene Oldowan locality of Kanjera South (South Rachuonyo District, Kenya) show that raw material selection and transport was an important aspect of Late Pliocene hominin adaptations. Yet the exact properties of stones that hominins were selecting remain enigmatic. Two potentially important features of artifact raw material are durability and fracture predictability. We investigate fracture predictability through mechanical tests of stone and investigations of the affect of stone properties on fracture patterns in archaeological collections. We investigate stone durability with actualistic studies of edge attrition combined with further mechanical tests of various lithologies. Oldowan hominins at Kanjera appear to have selected raw materials based on their durability. The ability for a stone to fracture consistently does not appear to be as important in hominin toolstone preference as previously assumed. Hominins that produced the assemblages at Kanjera South appear to have incorporated an extensive understanding of various attributes of raw material in the transport and production of stone artifacts. When combined with previous research on the transport patterns at Kanjera, the results of this study provide evidence for a more complex raw material acquisition strategy than has previously been suggested for Late Pliocene Oldowan hominins.     

Contribution to the geology of Failaka Island,Kuwait: Evidence from sedimentological and petrographic data from the NE part of the island

Kuwait–Georgian archaeological work at Failaka Island showed the need for geological study. Analysis of sediments related to drinking water-collecting cisterns was performed on a Late Islamic settlement (NE part of the island) in 2018. Field sedimentological, grain size and XRD analysis of the sediment profiles showed that the shallow (about 1 m deep) cone-shaped wells are dug in the loose, porous, cross-stratified calcareous coarse-grained quartz sandstones. Three upper layers of quartz sandstones in the profile have high infiltration rate and provide a rare yet ideal material for water retention. The fourth dense layer below, composed of very fine sand and silt fraction, tends to hinder water movement and forms a relatively impermeable water-resistant surface. Thus, the distribution patterns of clay content, grain sizes and porosity of the well-hosting sediments are favourable for freshwater infiltration and harvesting. An additional petrographic analysis was conducted on different types of rocks discovered on the archaeological site, used as building material and fragments of stone artifacts to identify their origin. It was established that archaeological building material is of local origin, whereas the source rocks for stone artifacts were imported.     

Damage Assessment of Unreinforced Stone Masonry Buildings After the 2010–2011 Canterbury Earthquakes

The sequence of earthquakes that has affected Christchurch and Canterbury since September 2010 has caused damage to a great number of buildings of all construction types. Following post-event damage surveys performed between April 2011 and June 2011, an inventory of the stone masonry buildings in Christchurch and surrounding areas was carried out in order to assemble a database containing the characteristic features of the building stock, as a basis for studying the vulnerability factors that might have influenced the seismic performance of the stone masonry building stock during the Canterbury earthquake sequence. The damage suffered by unreinforced stone masonry buildings is reported and different types of observed failures are described using a specific survey procedure currently in use in Italy. The observed performance of seismic retrofit interventions applied to stone masonry buildings is also described, as an understanding of the seismic response of these interventions is of fundamental importance for assessing the utility of such strengthening techniques when applied to unreinforced stone masonry structures.     

Remarks on Some of the Churches of Anglesey

Reconsideration of three published reports about the ruined church at Stone-by-Faversham is shown to lead to some new interpretations of its structure and history 1 especially when account is taken of evidence hitherto left latent in the building and of evidence as yet unpublished from an investigation in 1926. Moreover a new weapon for interpretation of the sequence of the several phases of the building has been developed by study of the extent to which material .from the earliest phase has been used in the fabric of later phases; and reasons are given for re-interpreting as nave-altars the masses of masonry which have in the past been regarded as part of a very confosing east wall of the first stone nave. Plans and .floor-levels are shown for the four principal phases of development 1 and we make a suggestion for a small change in the way the monument is displayed 1 in order to make its history more easily understood and also to protect its most ancient parts .from unnecessary risks. The substance of this paper was delivered to the Institute at its meeting on 11 February 1981.     

Excavations at Bamburgh: New Revelations in Light of Recent Investigations at the Core of the Castle Complex

The article documents the results of a series of investigations undertaken by the Bamburgh Research Project (BRP) within the Inner Ward of Bamburgh Castle, Northumberland between 1997 and 2010, using resistivity, ground penetrating radar survey, and limited excavation. Throughout the course of the investigation around the ruins of the medieval chapel, material evidence was found of Romano-British activity. Furthermore, stone structures of pre-twelfth-century date were revealed. Two phases of a possible early medieval defensive wall were identified beneath the north wall of the current chapel structure, and a stone building was found beneath the main body of the church which may represent part of the church of St Peter, mentioned by Bede.     

PETROGRAPHY AND PROVENANCE INTERPRETATION OF THE STONE MOULDS FOR BRONZE DAGGERS FROM THE GALDONG PREHISTORIC SITE, REPUBLIC OF KOREA*

This paper presents material characteristics and raw material provenance of the stone moulds for bronze slender daggers from Galdong. This type of bronze dagger is uniquely distributed in the Korean Peninsula and these stone moulds were the first to be found by excavation. The stone moulds were made of igneous hornblendite with course-grained holocrystalline textures. Based on petrological, mineralogical and geochemical characteristics, the original rock materials of the moulds were inferred to be derived from the Jangsu or Namwon areas which are about 50 km away from the excavation site. It is a notable achievement that this provenance study confirmed the domestic production of Korean-styled daggers.     

Fuel Fodder and Faeces: An Ethnographic and Botanical Study of Dung Fuel Use in Central Anatolia

Abstract

The Norse inhabited Greenland between AD 1000 and AD 1500 and, toward the end of the occupation, according to archaeological evidence, they were predominately marine mammal hunters. Despite the fact that marine resources became important for subsistence, the Norse Greenlanders settled the area in o?der to farm. This is indicated by site locations, faunal material, archaeobotanical, and palynological evidence.

Phytolith analysis from a quern stone, likely made from stone of local origin, found at Gården Under Sandet, a Norse farmstead in Greenland, was examined to determine if there was any evidence indicating domestic cereal processing. The phytoliths found on the quern stone can be associated with grasses and sedges, but the absence of dendritic phytoliths likely indicates that the quern stone was not used to grind seed. This preliminary study demonstrates that information about Norse agriculture may be obtained by examining the phytolith remains from a quern stone.     

Unmodified lithic material at Olduvai Bed I: manuports or ecofacts?

The existence of high percentages of so-called manuports in the Olduvai sequence has given way to abundant papers on the behavioural explanation of such accumulations of raw material. For this paper, we performed a first-hand re-examination of the lithic collections of two of the most relevant sites in Olduvai Bed I (FLK Zinj and FLK North). The analysis has unearthed extremely significant differences between the unmodified lithic material (the so-called manuports) and the other stone collections, which has demanded the search for alternative hypotheses to explain the presence of the supposed manuports at these sites. Thus, we have revised the site formation processes and have compared them with other similar sedimentary contexts in Olduvai and in nearby lacustrine basins. On the basis of our findings, we demonstrate the existence of different sized clasts in low energy contexts, and propose a natural deposition as the answer to the existence of the supposed manuports at Olduvai Bed I. In all, our analysis suggests that a great part of the unmodified lithic material from the Olduvai sites is not indicative of human action but the product of natural causes, thus being ecofacts and not genuine manuports.

Effects of residential exposure to steel mills and coking works on birth weight and preterm births among residents of Sydney, Nova Scotia

The Sydney Tar Ponds in Sydney, Nova Scotia, Canada, have been referred to as the most contaminated industrial site in the country. Area residents, aware of the contamination for close to 25 years, are very concerned about their health: past, present and future. In particular, they are concerned about cancer; this is followed closely by reproductive health concerns. The objective of this study was to assess the prevalence and determinants of birth weight and preterm birth among residents living in proximity to an industrial site contaminated with a mix of industrial wastes arising from a former steel mill and coking works (the Tar Ponds) in Sydney, Nova Scotia, Canada. A telephone survey was administered to 500 randomly selected women living in proximity to the site to document reproductive histories. The respondents reported 904 live birth pregnancies occurring in Sydney. The mean birth weight reported for live birth pregnancies was 3,391 g (standard deviation: 570). The reported prevalence of preterm births was 7 percent. Linear regression analyses showed a reduction in birth weight of approximately 85 g among residents in a zone estimated to have higher levels of deposition of airborne effluent from the site. Multivariate logistic regression analyses showed a decrease in the risk of preterm birth as residential distance from the site increased (odds ratio 0.65, 95 percent confidence interval 0.42, 0.98). These data suggest that community exposure to industrial contaminants had some, but little, impact on reported birth weights in this sample of respondents. The apparent increase in risk for preterm births suggests further investigation may be warranted, particularly in light of community concerns. Follow‐up investigations using validated birth records and more sensitive measures of environmental exposure could be used to confirm the findings and further explore the intra‐urban variation in health outcomes. These findings underscore the importance of ongoing clean‐up efforts in Sydney.     

Vasilikos Valley Project: Fourth Preliminary Report, 1979–1980

Abstract

During the fourth season of the Vasilikos Valley Project in the Larnaca District of southern Cyprus, excavations were continued at the Aceramic and Ceramic Neolithic site of Kalavasos-Tenta. Excavation on the west side of the top of the site revealed more of the plan of the earliest curvilinear building that underlies the stone complex. Elsewhere on the top of the site, further mud-brick and stone structures were uncovered, and a unique wall painting was found on the central pier of one building. Excavations in the Lower South Slope area confirmed the existence of a deep ditch outside the outer settlement wall. Five Aceramic phase burials were excavated in different parts of the site. Investigation of the Ceramic phase deposits on the eastern flanks of the site revealed a series of pits, but no standing architectural remains.

Excavations at the Chalcolithic site of Kalavasos-Ayious on the east side of the valley were also continued. A series of pits of widely varying size was brought to light in several different areas of the site. The largest pits contained numerous artifacts, sometimes in situ on distinct surfaces. At the north end of the site three pits were found connected by subterranean tunnels.

Rescue excavations, lasting from July 1979 through February 1980. were also undertaken at the Late Bronze Age site of A. Dhimitrios, a short distance to the south of Tenta. An extensive architectural complex of finely built stone structures was uncovered within the line of the new Nicosia-Limassol highway. The quality of the building, and the clear degree of planning that underlies the whole architectural layout, betoken a site of considerable importance. The architectural levels on the site may be dated to a late phase of Late Cypriote II, but one of the tombs also contains material of Late Cypriote I or early Late Cypriote II date.

A systematic field survey of the southern half of the Vasilikos valley, employing a regularly spaced series of transects, revealed a number of additional sites of varying type and period. A chronological outline of prehistoric Cyprus is provided in Table 1. Specialist reports on geographical, fluvial geomorphological, faunal, and conservation studies are also included.

SURFACE SCATTERS of BUILDING STONE: ENHANCING FIELD SURVEY WORK

It is observable - from standing buildings-that the stone used in the study area of the East Brittany Survey has for the most part travelled a very short distance (< 5 km), whether the building is grand or simple. Excavation has demonstrated that the same is true of structures of earlier periods, although Roman building is differentiated by its preference for the very hard stones that occur to the north of the area. Surface scatters of building stone on modern arable fields, if carefully observed, are a useful tool for locating stone-built settlements of the historic period and scatters of Cambrian siltstones can point to the location of medieval seigneurial settlements. Manuring scatters of roofing slate, which can be differentiated by period, are a useful tool for defining the arable worked from settlements, especially in the later and post-medieval periods, and therefore for mapping the changing patterns of land-use. With sufficient training of volunteers or of a research team, a large body of data can be gathered very economically.     

Non-destructive pXRF of mafic stone tools

Archaeological use of non-destructive pXRF has been most systematically applied to the classification and provenancing of volcanic glass (obsidian) artefacts. Comparable work has yet to be developed for non-vitreous artefacts. We report results of pXRF analysis for a sample of grey to black (mafic) aboriginal hatchets from Sydney and adjacent coastal regions to the north and south. The study shows both broad and detailed classification is achievable depending on rock type and degree of elemental depletion or enrichment of the samples. PXRF analysis reveals not only distinct patterns of resource use between the three regions of this study but also enables a high degree of geographic resolution in the case of the basalt artefacts of our sample. We conclude that non-destructive pXRF is effective for reliable characterisation of non-vitreous stone artefacts that have a sufficiently complex and enriched compositional signature (i.e., unaltered basalts); with ∼50% of the basalt hatchets in our sample matched with spatially and geologically specific sources.
