Non-invasive archaeological exploration in stratigraphically complex rural settings: an example from Ferento (Viterbo, Italy)

This paper presents the results of a ground penetrating radar (GPR) survey conducted in the rural area of the ancient city of Ferento near Viterbo (Northern Latium, Italy), where the visible ruins testify an uninterrupted history from the Etruscan to the Medieval period. The soil covering the ruins has been intensively ploughed, cultivated and used for pasture over the centuries, and is characterised by a high content of clay minerals. In this scenario, the use of GPR is particularly difficult due to both possible ‘false positive anomalies’ and strong signal attenuation. In order to reconstruct the geometrical shape and size of the geophysical anomalies related to a medieval dwelling, multi-profile GPR data were collected in two different areas, using radar equipped with 250-MHz antennas. 2D and pseudo-3D migrated maps were created and signal velocity analysis was performed to estimate the target depths. Despite the clayey-calcareous material, the results show a good signal penetration and allow a clear reconstruction of the shape of the buried ruins, confirming that the anomalies are due to medieval buildings located at a depth in agreement with what was observed on the archaeological stratigraphy. Furthermore, our study suggests that in radar data interpretation, caution should be used if the surveyed area was subjected to prolonged and intensive agriculture.     

The conservation and management of mudbrick buildings at Tell Qasile,Israel

Abstract

Tell Qasile, in the area of the Eretz Israel Museum in north Tel Aviv, is the location of a small town founded in the twelfth century BCE. The site has significant importance for the study of various aspects of the Iron Age period in Israel. The buildings at the site were constructed of mudbricks on stone foundations. Conservation of buildings at the site was carried out using three methods: 1) building roofs (in roofed areas no other conservation was needed); 2) conserving mudbrick walls by plastering them in modern plaster made up in imitation of ancient building material; 3) full restoration of buildings up to roof level (carried out in one case). These methods were successful, and, due to the location of the site within a large museum compound, it is utilized for archaeological education, mainly of schoolchildren.     

GPR survey at Lapa do Santo archaeological site,Lagoa Santa karstic region,Minas Gerais state,Brazil

In this work we present and discuss the results of a novel and timely GPR-2D and GPR-3D survey performed at an archaeological rock shelter site, Lapa do Santo, localized in the karstic region of Lagoa Santa, central Brazil. A total of 113 ground-penetrating radar profiles were acquired with 200 MHz and 400 MHz shielded antennas aiming in identifying geological and archaeological anomalies in order to assist archaeologists in an excavation program. The GPR results indicated clear geophysical anomalies characterized by hyperbolic reflections and areas with high amplitude sub-horizontal electromagnetic waves. The anomalies observed by GPR were confirmed by the excavation of test units, allowing the identification anthropogenic features such as a fire-hearth structure and wooden artifact, and natural features, such as, tree roots and rocky bodies such as speleothems, boulders and bedrock. The results showed the efficiency of GPR method in identifying potential buried archaeological targets in cave sites within a karstic area, and they oriented to archaeological excavations, reducing costs and increasing the probability of finding archaeological targets in the initial stages of a project.

MOUND BUILDING AT LAKE JACKSON (8LE1), TALLAHASSEE,FLORIDA: NEW INSIGHTS FROM GROUND PENETRATING RADAR

Abstract

The Lake Jackson Mounds site (8LE1), located near Tallahassee, Florida, has long been considered to be a frontier Mississippian center. This assertion is primarily based on elaborate burial goods recovered during salvage excavations in the 1970s. Ground penetrating radar (GPR) on the two largest intact mounds at Lake Jackson revealed new information about their morphology and construction histories. These findings demonstrate that mound-building practices at the site were distinct from earlier, local Woodland mound-building traditions, and more similar to those of other Mississippian centers, such as Etowah and Moundville. Lake Jackson revitalized mound building in the Tallahassee area under the influence of external connections with groups in the Mississippian interaction network. These findings show how mound building was an integral practice for expressing and expanding Mississippian ideologies and rituals. This work also shows the utility of GPR in exploring mounds' morphologies and construction histories.     

Bakal Culture Dwelling At Settlement Ust-Tersyuk-1

The study attempts to reconstruct the Bakal culture dwelling at fortifi ed settlement Ust-Tersyuk-1, introducing new data on house-building among the medieval population of the forest-steppe Trans-Urals region. It has been established that in addition to well-known, light frame buildings such as chums and yurts, the Bakal population also built stationary, semiunderground dwellings suitable for habitation throughout the year. These dwellings had a frame and pillar structure, inclined walls made of poles and twigs and a slightly sloping roof. The walls were plastered with clay on the inside and covered with sod on the outside. The remains of the dwelling, a hearth and a sleeping platform, have made it possible to reconstruct the dwelling's interior furnishing.     

Joint geophysical measurements to investigate the Rossano of Vaglio archaeological site (Basilicata Region,Southern Italy)

A high resolution geophysical survey was carried out in the archaeological site of Rossano di Vaglio (Basilicata Region, Southern Italy), where an important ancient sanctuary is located. It was built during the IV century B.C. and devoted to the goddess Mephitis. The sanctuary rises in an area affected by a multiple and retrogressive rototraslational landslide, historically and presently subject to reactivation. The main objective of this work was the identification of buried structures of archaeological interest in an area designated by the Archaeological Superintendence of the Basilicata Region. The study was performed by means of the use of high resolution geophysical surveys. In particular, we made use of the joint application of three highly sensitive and non-invasive geophysical techniques, namely the Geoelectrical, the Magnetic and the Ground Probing Radar (GPR) methodologies. In such a way, we obtained two important results: first, we provided the archaeologists with information about the limits of the areas to be excavated; second, we could verify in real time the reliability of the geophysical results. The experimental results showed four main magnetic anomalies in the area of study, in agreement with the GPR results obtained for the same target. Finally, a partial excavation test of the investigated area revealed a buried building structure, located in correspondence of an anomaly identified by means of the geophysical prospecting.     

Middle east architectural traditions in golden horde mansion construction

The article deals with the largest mansion-type buildings in the Golden Horde towns of the Lower Volga region. These buildings had many rooms and walls made of hard-burned and adobe bricks. A large ceremonial hall was located at the center of the building; vestibule premises were located adjacent to the hall on the northern and southern sides; residential and utility rooms occupied the eastern and the western wings. Golden Horde mansions are compared with the palaces and mansions of China, Mongolia, and the countries of the Middle East. The infl uence of the architectural traditions of these countries led to the emergence of an original building type based both on a typical Western Central Asian layout, and principles of organizing space borrowed from Eastern Central Asia.

Site Effects Analyses in the Old City Center of Trieste (NE Italy) Using Accelerometric Data

The influence of local geology and soil conditions on the intensity and the amplification of ground shaking are well known. Part of the old city center of Trieste is built on the site of a former salina, placed at a river mouth and is characterized by soft sediments several tens of meters thick. A new accelerometric station has been recently installed in a historical building, in order to analyse earthquake-induced site amplifications. This station has recorded five regional earthquakes and the related records are compared to those obtained at a nearby bedrock-installed accelerometeric station. Fourier and response spectra for all components are computed and both the H/V ratio and the reference station techniques are used to assess site effects. Noise measurements performed in the historical building, where the accelerometer is located, confirm these results. Relevant amplifications are detected in the frequency range of 2–4 Hz, particularly important for the type of buildings present in this part of the city.     

A High-Performance Quadrilateral Flat Shell Element for Seismic Collapse Simulation of Tall Buildings and Its Implementation in OpenSees

Shear walls are important lateral force-resistant components of tall buildings. Hence, a reliable numerical model that can accurately represent the mechanical characteristics and large deformations of shear walls is critical for realistic collapse simulation of tall buildings. Based on the theory of generalized conforming element, a high-performance quadrilateral flat shell element, NLDKGQ, accounting for the large deformation using the updated Lagrangian formulation, is proposed herein and implemented in OpenSees. The reliability of NLDKGQ is validated using classical benchmark problems and reinforced concrete specimens. In addition, its capability in simulating the collapse of a tall building is also demonstrated.     

The Excavation of a Brick Clamp at Shotesham St. Mary,Norfolk, 1969

Abstract

Rescue excavations in the small village of Llanmaes investigated an area of earthworks indicating the presence of several buildings. Medieval evidence was largely confined to finds. Three late 17th-century properties were examined; it is possible that they represent a planned development on the east side of the village green in response to population expansion in the Vale of Glamorgan. The buildings are of simple two-roomed plan, and would appear to be tenements of low status. One of the buildings produced evidence of smithying. A large group of metal finds of agricultural and domestic use was found, as was a closely-dated assemblage of wine bottles; a large midden deposit on the north edge of the site contained a very large group of post-medieval pottery. The buildings were abandoned by the end of the 18th century, presumably following rationalization of the local settlement morphology and farming. Thus the site represents a short-lived expansion in low-status rural housing at the time of the ‘Great Rebuilding’.     

Assessing Seismic Behavior of a Masonry Historic Building considering Soil-Foundation-Structure Interaction (Case Study of Arge-Tabriz)

ABSTRACT

Historic heritage buildings are a part of historic basis of each society and an economic resource. Therefore, preserving and maintenance of these buildings are cultural, economic and social demand. This research investigates the seismic performance of a historical building named Arg of Tabriz (Arge Alishah) that dates back to 14th century and is located at the city center of Tabriz (NW of Iran). Static, modal, and finally nonlinear dynamic (time history) analysis were performed by both “Considering Soil-Structure Interaction (SSI)” and “fixed base (ignoring SSI)” Cases.

It is found from the results that, SSI extremely affects mode shapes and their frequencies and depending on the frequency content of the records, can has an incremental or decremental effect on structural responses. As expected, the building of Arg could carry gravity loads easily and despite its stability against earthquake loading in fixed base case, showed a weakness (especially in eastern and western walls direction) and overturned when it was analyzed in SSI case because of yielding of the surrounding soil.     

Architecture and Urbanism in the Fortified Settlement of Pech Maho (Sigean,France) in the Third Century BC: A Social and Economic Perspective

This paper offers a synthesis of the urbanism and architecture of Pech Maho (Sigean) from a social and economic point of view. Its aim is to highlight the specificities of this settlement in the context of the Late Iron Age between south France and north‐east Spain. During the third century BC, this small site had an impressive defensive system, as well as quite a complex urban framework. The constructed blocks excavated so far show a predominance of multicellular buildings that testify to a wide range of ground plans. Most of the spaces seem to have been devoted to specialized activities of a clear economic orientation, whilst other buildings or spaces have a strong symbolic nature. Rooms used exclusively for domestic tasks are in the minority, while a large dwelling in the central area appears to have been a private residential unit. All of this suggests that Pech Maho would have been an economic centre, as well as the residence of an elite that would have exerted control over the productive and trading activities, in a context that clearly evokes that of an emporion.     

Bystry Kulyogan-38 –Bronze Age Fortified Dwelling In The Surgut Ob Area

In 2000, archaeologists from Yekaterinburg and Surgut excavated the preserved portion (380 sq. m) of the Bronze Age fortifi ed settlement situated on the Bystry Kulyogan River, right bank of the Ob River, 35 km west of Surgut. The settlement was initially estimated to be approximately 650 sq. m in size. An isolated dwelling was located on a small sandy promontory. It was protected by an arcuate moat and probably by a palisade along the perimeter. The dwelling is rectangular in plan and resembles a tall truncated pyramid with rounded angles. It is characterized by a frame-pole construction with vertical load bearing posts, inclined log and pole walls, and fl at or very low gable roof similar to those encountered among traditional Khanty surface dwellings or above grave structures. Walls were fi xed by sandy mounds along the outer perimeter. The largest portion of the dwelling was occupied by a rectangular pit with vertical walls 0.4–0.9 m high sheeted with half-beams or half-section timber. Plank beds were located along the walls. The elevated shelf between the pit and walls was used to store kitchen utensils, tools, and provisions. The Bronze Age assemblage includes 33 stone artifacts and 1640 fragments of at least 25 Kulyogan type vessels. Vessels are jar-like with fl at bottom, decorated with comb and pit patterns. The site is preliminarily dated to the fi rst half or the fi rst third of the 2nd millennium BC.     

Determination of the influence of soil parameters and sample density on ground-penetrating radar: a case study of a Roman picket in Lower Bavaria

Ground-penetrating radar (GPR) surveys are very much influenced by the site-specific physical properties, soil parameters and the sample density of the radar pulses. According to the electromagnetic theory, the transmission and reflection of electromagnetic waves is dominated by the conductivity, dielectric permittivity and the soil moisture. Therefore, it is advisable to measure these parameters in advance of a GPR survey. Commonly, this is not possible directly with the standard common-offset GPR arrays. To overcome this problem, we adapted and applied a direct method called time-domain reflectometry to a selected case study of the Roman picket Hienheim at the Raetischer Limes in Lower Bavaria. Furthermore, we present some important results relating to the profile spacing and orientation of GPR surveys and the site-specific soil parameters. The location and the identification of the archaeological features were successful by all geophysical methods. However, the application of all these geophysical methods like magnetometry, resistivity and GPR in addition with aerial photography and Airborne Laserscanning exemplifies the advantages of an integrated survey to achieve a comprehensive result of an archaeological site. The Roman picket of Hienheim shows up differently in all results, as each one traces the archaeological remains according to a specific physical parameter. Resistivity and radar are best to resolve buried stone structures like the walls of the picket or stone-filled ditches. In contrary, magnetometry benefits of the magnetic contrast between the limestone walls and the surrounding soil.     

Mississippian Habitation Components at Dickson Mounds in the Central Illinois River Valley

The Myer-Dickson area is a habitation component of the well-known Spoon River Mississippian mortuary site Dickson Mounds. About 20 domestic and public buildings were excavated at the site in the 1960s and 1970s, including the second-largest Mississippian building known in Illinois. Though sometimes characterized as a nucleated village, detailed analysis of material remains and their spatial distribution suggests two and possibly three periods of use during the Larson phase between A.D. 1200 and 1300. The large public building is one of several structures bordering a plaza, all of which are almost totally devoid of Mississippian artifacts. Domestic use of other sections of the site during the late Larson phase is part of a broader pattern of dispersed settlement on valley-edge ridges, a pattern that indicates at least some periods when fears of raiding were lessened despite the presence of contemporaneous palisaded towns.
