Geoarchaeology is the archaeological subfield that focuses on archaeological information retrieval and problem solving utilizing the methods of geological investigation. Archaeological recovery and analysis are already geoarchaeological in the most fundamental sense because buried remains are contained within and removed from an essentially geological context. Yet geoarchaeological research goes beyond this simple relationship and attempts to build collaborative links between specialists in archaeology and the earth sciences to produce new knowledge about past human behavior using the technical information and methods of the geosciences. The principal goals of geoarchaeology lie in understanding the relationships between humans and their environment. These goals include (1) how cultures adjust to their ecosystem through time, (2) what earth science factors were related to the evolutionary emergence of humankind, and (3) which methodological tools involving analysis of sediments and landforms, documentation and explanation of change in buried materials, and measurement of time will allow access to new aspects of the past. This encyclopedia defines terms, introduces problems, describes techniques, and discusses theory and strategy, all in a format designed to make specialized details accessible to the public as well as practitioners. It covers subjects in environmental archaeology, dating, materials analysis, and paleoecology, all of which represent different sources of specialist knowledge that must be shared in order to reconstruct, analyze, and explain the record of the human past. It will not specifically cover sites, civilizations, and ancient cultures, etc., that are better described in other encyclopedias of world archaeology. The Editor Allan S. Gilbert is Professor of Anthropology at Fordham University in the Bronx, New York. He holds a B.A. from Rutgers University, and his M.A., M.Phil., and Ph.D. were earned at Columbia University. His areas of research interest include the Near East (late prehistory and early historic periods) as well as the Middle Atlantic region of the U.S. (historical archaeology). His specializations are in archaeozoology of the Near East and geoarchaeology, especially mineralogy and compositional analysis of pottery and building materials. Publications have covered a range of subjects, including ancient pastoralism, faunal quantification, skeletal microanatomy, brick geochemistry, and two co-edited volumes on the marine geology and geoarchaeology of the Black Sea basin.

Optical Dating of Quartz from Young Deposits available in PDF, EPUB and Kindle. Optically Stimulated Luminescence (OSL) dating is a tool used in Quaternary Geology for assessing ages of depositional mineral grains such as quartz, feldspars and zircons. In particular, OSL showed to be exceptionally robust and reliable for dating quartz samples. OSL dating relies on the assumption that the luminescence signal of grains is fully reset to zero by sunlight exposure before deposition. If this requirement is not fulfilled (i.e. grains were 'poorly-bleached'), ages may be grossly overestimated. In particular, poor-bleaching can significantly affect age estimations of young sediments. Standard procedures for estimating the burial dose of a sediment make use of a large number of grains (aliquot) that is measured simultaneously. This approach has been shown to work well, but only on homogeneously bleached sediments. An alternative way to investigate poor-bleaching within a sample is to measure the OSL signal from individual grains rather than from aliquots made up of several thousands of grains. The advantage is that individual grains with large doses (possibly due to poor-bleaching) can be identified and dealt with. detectable signals and luminescence responses are weak. The aim of this publication is to determine the feasibility of applying dating techniques to individual grains of quartz from deposits formed within the last 300 years.

Optically Stimulated Luminescence (OSL) Dating in the Amazonian Wetlands available in PDF, EPUB and Kindle. Optically stimulated luminescence (OSL) dating has proven to be extremely useful for establishing the Late Quaternary chronological framework in many areas of the Brazilian territory. In this region dominated by tropical climate, OSL dating can be more extensively applied than radiocarbon dating due to the generally low potential for the preservation of organic matter in sedimentary samples. This problem is especially critical in areas of the Amazonian lowlands, because of the hot climate and high precipitation rates. The abundance of quartz grains deposited in fluvial and aeolian environments over this region favours OSL dating. More than 20 years of continuous and collaborative work has resulted in the creation of an extensive OSL age database for Late Quaternary sedimentary deposits in the Amazonian lowlands. This effort has contributed to improving the paleoenvironmental and paleoclimatic reconstructions of this region within this period. This book discusses the state of art of OSL dating of Late Quaternary deposits in the Amazonian lowlands, focusing on providing an introduction to dating principles using OSL, and defining the application of OSL techniques as a dating method. It also offers a statistical study and calculation of equivalent dose and annual dose rates, details the sampling and experimental apparatus, and considers the difficulties and adaptation techniques in dating Late Quaternary strata in the Amazonian lowlands.

Impact of the Environment on Human Migration in Eurasia available in PDF, EPUB and Kindle. This book is a collection of the articles presented at the NATO Advanced Research Workshop (ARW 979859) held in St. Petersburg, from the 15-18 November 2003 in the Hermitage Museum. The title of the workshop was “The impact of the environment on Human Migration in Eurasia”. More than 40 scientists from Russia, Ukraine, Kazakhstan, Poland, Germany, Switzerland, The Netherlands, United Kingdom, Belgium, Finland, Lithuania and Latvia took part. The themes of the workshop focused on the origin, development, interactions, and migrations of prehistoric and ancient populations, specifically the Scythians, in Eurasia and their relationships with the environment of the time. The discussion of these questions necessitated the participation of specialists from a wide range of academic fields. Beyond any doubt, the environment played an important role in the life of ancient nomadic populations, forming the basis of their economies and influencing various aspects of their mode of life. In this respect, the collaboration of specialists in the Humanities and Science is essential for the solution of scientific questions concerning these peoples. Over the past few years, a large amount of new proxy data related to environmental changes during the Pleistocene and the Holocene and their impact on human life has become available. Our discussion was predominantly limited to environmental changes related to the Holocene. In st this period of about 10000 years, the main focus was on the 1 millennium BC.
