Petrographic analysis and INAA geochemistry of prehistoric ceramics from Robinson Pueblo, New Mexico

The examination of thin sections is a successful method for discovering provenance groupings of archaeological ceramics if non-clay inclusions in pottery paste can be identified with petrographically distinctive geologic sources. When this is not the case, geochemical analysis must be employed to search for more subtle evidence of such groupings. This situation is likely to arise in studies, such as the present one, where the objective is to discern local or subregional patterns of pottery manufacture and exchange. Ninety potsherds from site LA46326 in New Mexico were subjected to both INAA and petrographic analysis. The results of this conjoint approach are assessed in relation to geochemical theory and are analysed graphically and statistically.     

The Protection of the Site: Discursive Formation and Self-identification in Contemporary Society

The paper argues that rescue archaeological activities in Japan create a discursive space where the future protection and management of the site is debated, notably between academic archaeologists, developers (the financial/administrative force) and the media. This discursive space is more and more dominated by the media agenda, to which the academic force largely conforms.This is connected with the nature of the stability of the lives of the rescue excavation officers themselves, in contradistinction to that of the general public.     

SITE AMPLIFICATION FACTOR IN ANCHORAGE,ALASKA BASED ON LONG PERIOD MICROTREMORS

Long period microtremors with periods ranging from 0.5 to 10 seconds were measured in the Anchorage metropolitan area. Two horizontal components of motion were recorded at 81 sites uniformly distributed throughout the basin with spatial resolution of about 2 km. Recording at each site was done for 300 seconds with a sampling rate of 20 Hz. Repeated measurements were performed at a bedrock reference site simultaneously with the measurements in the field. The measurements were completed in six days. In addition, multiple recordings were obtained concurrently at the reference bedrock site and a sediment site. Based on these measurements the Fourier spectra were calculated for each of the site. Ground motion amplification is determined in terms of spectral ratio of horizontal spectral amplitudes at a sediment site and the reference bedrock site. Mean spectral ratio contours were evaluated for different period bands. The results show that for period band 3 to 5 seconds the spectral ratio contours agree well with the ground failure susceptiblity map of Anchorage.     

Probabilistic Seismic Hazard Model of West Bengal,India

We deliver a next-generation Probabilistic Seismic Hazard model of West Bengal based on improved seismogenic source characterization considering both the Layered Polygonal sources & Tectonic sources in the hypocentral depth range of 0–25 km & 25–70 km, seismic local-specific site condition, and adaption of appropriate region specific ground motion prediction equations in a logic tree framework. The surface consistent Probabilistic seismic hazard distribution in terms of Peak Ground Acceleration (PGA) & 5% damped Pseudo Spectral Acceleration (PSA) at different time periods for 10% probability of exceedance in 50 years have been generated and the design response spectra computed.     

Seeds/fruits,pollen and parasite remains as evidence of site function: piazza Garibaldi – Parma (N Italy) in Roman and Mediaeval times

Archaeobotanical analyses were carried out on layers from the site of Piazza Garibaldi in Parma, a town located in the plain of Emilia Romagna, in northern Italy. The layers dated to the 3rd–2nd centuries BC, around the time of the foundation of the Roman town, and to the 10th–11th centuries AD. According to archaeological data, the site was a sacred area in Roman times, while it was a market square in Mediaeval times. Data from pollen and seeds/fruits were useful for both palaeoenvironmental and palaeoethnobotanical reconstructions, and together with NPPs including parasite remains contributed to add details on the function of the site in the different chronological phases.     

河南灵宝市北阳平遗址考古勘探报告

为深入认识豫西灵宝盆地仰韶文化时期大型遗址的聚落内部情况,2018年3~5月,河南省文物考古研究院等单位对河南灵宝北阳平遗址进行了系统性考古勘探。本次工作明确这是一处以仰韶文化为主体的大型聚落遗址,发现的遗迹主要有房址、壕沟等,基本搞清了聚落范围、面积、重要遗迹分布、聚落布局和功能分区等,取得了重要成果。     

河北省石家庄市石邑城遗址出土动物遗存的初步研究

文章以石邑城遗址2017年出土的动物骨骼遗存为研究对象,应用种属鉴定、量化统计、年龄结构分析等方法讨论了石邑城遗址先民对动物资源的利用模式;并结合发掘区是手工业区的性质探讨了石邑城遗址先民制骨手工业的生产方式及其特征。     

大遗址历史文化内涵的展示与阐释

大遗址历史文化内涵非常丰富,但如何将其生动地呈现给观众并非易事,展示和阐释是最基本的两种方式。展示旨在呈现大遗址的本体及相关信息,阐释是展示的延伸和补充,是运用更丰富的手段多方位诠释大遗址的历史文化内涵,给观众以更全面的认知。由于大遗址有诸多未知因素．因此对其展示和阐释也不可能是一次性或完结式的,需要随着考古学及相关科学研究的深入不断充实、调整和完善。     

毕节青场瓦窑商周遗址发掘主要收获

青场瓦窑遗址是贵州商周时期非常重要的一处古文化遗址。2008年10月至12月对其进行了第二次发掘,清理出更加丰富的遗迹,出土大量陶石器等遗物,对其文化特征和发展演变有了突破性认识。出土资料表明,它与分布在乌蒙山西缘的鸡公山文化遗存有一定联系但是独立发展的两个文化系统,原因与地理阻隔有关,瓦窑遗址在发展中更多地受到来自其北部四川盆地商周时期古文化的影响。     

关于建设国家考古遗址公园的一些意见——在“2009大遗址保护·良渚论坛”上的发言

国家考古遗址公园的提出及相关法规文件的颁布是实践大遗址保护的新形式,为城市建设和大遗址保护找到了一个结合点,为城市的文化建设找到了新内容。国家考古遗址公园的建设,要有长期性、探索性的战略思路,要以保护为前提,以持续的、与时俱进的考古工作及不断进步的文物保护技术为支撑,并制订一定阶段的遗址保护规划和建设蓝图。要准确定性、定位国家考古遗址公园,并筹建遗址博物馆,立足文物的文化建设,探寻考古学文化的文化特质和考古学文化的文化演进规律。
