Luminescence Dating in Archaeology, Anthropology, and Geoarchaeology : An Overview
From where did they come and what routes did they take? These questions have gripped scientists for decades, but until recently answers have proven difficult to find. New techniques of molecular genetic analysis, and a reinvigorated search for early archaeological sites across the western hemisphere, recently have led to some astounding results. The route taken by the first explorers appears to have been along the recently deglaciated north Pacific coastline. Until recently, it was generally believed that about Today, we realize that the peopling of the Americas was a much more complex process, because of two significant developments that occurred during the past decade.

Dinolungs 29 Oct Brian Switek reports on a study that investigated bony features correlated with lung morphology in birds and crocodiles, to see how much dinosaur lungs resembled birds: The bottom line is that dinosaurs probably had lungs that were similar in morphology and function to those of living birds. Very non-bird like dinosaurs like Triceratops were part of this study, as well as those closely related to the origin of birds.
This is one of those anatomical observations that is very difficult to examine with the kind of evidence left from dinosaurs, and yet to most people it probably seems like it should be obvious. Newark cider was both a point of pride and big business for the region — requested by name, reportedly lauded by George Washington and produced by dozens of Newark-area cideries with acres of orchards.
Luminescence dating (including thermoluminescence and optically stimulated luminescence) is a type of dating methodology that measures the amount of light emitted from energy stored in certain rock types and derived soils to obtain an absolute date for a specific event that occurred in the past.
Brown Department of Anthropology Some of your professors may ask you to complete assignments using reliable or valid sources. Finding and recognizing authoritative sources is one foundation of critical thinking. Peer-review is one technique that scholars use to ensure that publications meet scientific standards. Because archaeology is such a broad field—its coverage ranges from the arts and art history to the humanities to the social sciences to the natural sciences—it is difficult to predict where you will find articles.
Occasionally, archaeological articles are published in specialized non-archaeological scientific journals, such as journals on chemistry, geology, or spectroscopy. There are also many hundreds of archaeology journals published around the world. Because archaeological sites and cultures are localized phenomena, there are local and regional archaeology journals all around the world.

The bays contain trees such as black gum , bald cypress , pond cypress, sweet bay , loblolly bay , red bay , sweet gum , maple , magnolia , pond pine , and shrubs such as fetterbush , clethra, sumac , button bush , zenobia, and gallberry. Plants common in Carolina bays are water lilies , sedges and various grasses.
Several carnivorous plants inhabit Carolina bays, including bladderwort , butterwort , pitcher plant , and sundew. Some of the bays have been greatly modified within human history, under pressure from farming , highway building, housing developments and golf courses. It has been drained and is mostly used for tree farming today.
luminescence dating provides a tool to directly date the time of construction. Luminescence is the light emitted from minerals, such as quartz and feldspar following an exposure to ionizing radiation.
Description Book — xv, pages: Nielsen Book Data A guide to the systematic understanding of the geoarchaeological matrix Reconstructing Archaeological Sites offers an important text that puts the focus on basic theoretical and practical aspects of depositional processes in an archaeological site. It contains an in-depth discussion on the role of stratigraphy that helps determine how deposits are organised in time and space. The authors — two experts in the field — include the information needed to help recognise depositional systems, processes and stratigraphic units that aid in the interpreting the stratigraphy and deposits of a site in the field.
The book is filled with practical tools, numerous illustrative examples, drawings and photos as well as compelling descriptions that help visualise depositional processes and clarify how these build the stratigraphy of a site. Based on the authors’ years of experience, the book offers a holistic approach to the study of archaeological deposits that spans the broad fundamental aspects to the smallest details.

These footprints were within a soft, damp volcanic ash along a lakeshore shortly after a volcanic eruption. This type of volcanic tuff is known as the Xalnene. Samples of the Xalnene tuff were sent off to the Berkeley Geochronology Center for argon-argon and paleomagnetic dating.
The team that initially found the prints have revisited the dating of the Xalnene tuff at Toloquilla.
With improvements in methodology and instrumentation, luminescence dating is becoming a much more useful chronometric tool in archaeology. Procedures for dating ceramics are relatively routine and their accuracy has been demonstrated in a number of studies.
This article contributes to this debate by presenting new d 13 C and d 15 N data from the human populations that occupied the Marac a region of the mouth of the Amazon river, around BP years before present. It directly compares these newly generated results to previously published human isotope data from neighbouring Maraj o Island Marajoara phase, to BP , as well as other areas in the lowland Neotropics, in an attempt to build a bigger picture of the dietary habits of the Lower Amazon pre-colonial populations.
The overall results suggest that the populations that occupied the mouth of the Amazon after BP had diets based on the exploitation of fish and a wide range of C 3 plant resources, as well as possibly having a minor C 4 or CAM component. The data presented are also consistent with an emerging consensus that there was no single adaptive pattern for ancient Amazonian populations and proposes that diversified economic strategies based on wild and cultivated plants combined with the exploitation of faunal resources could have developed over time and sustained long-term successful patterns of human occupations.
These included the reduction of the body by means of mutilation, defleshing, tooth removal, exposure to fire and possibly cannibalism, followed by the secondary burial of the remains according to strict rules. In a later period, pits were filled with disarticulated bones of a single individual without signs of body manipulation, demonstrating that the region was inhabited by dynamic groups in constant transformation over a period of centuries.

Archaeology and Anthropology Archaeology and Anthropology Earth and Ecosystem scientists conduct a wide variety of archaeological research in regions ranging from the arid Southwestern U. The research ranges from studies of earlier civilizations to studies focused on the preservation of historic legacies from recent events such as nuclear testing at the Nevada National Security Site formerly, the Nevada Test Site.
Our archaeologists are conducting historic artifact inventories with federal agencies to facilitate stewardship decisions as they appropriate lands for specific uses. These land uses include military training, construction of power lines and prospecting and development for renewable energy projects including solar, wind and geothermal. Archaeologists at DRI make use of modern techniques including ground penetrating radar GPR and light detection and ranging LiDAR , often in combination with geographic information systems GIS and specialized laboratories equipped with traditional light and electron microscopes.

Jay’s arrival in Australia in June to begin the archaeology programme in the Department of Anthropology and Sociology at the University of Queensland marked two important events in the history of archaeology in this country. Firstly it provided a local focus for archaeology north of the Tweed River, thus continuing to expand the discipline beyond the dominant Sydney Canberra axis. Secondly Jay was an important addition to the tiny number of American-trained archaeologists practising in Australia at that time.
Indeed, because of Jay’s fundamental role in developing the archaeology teaching at UQ, that school became and has remained the most ‘American’ among Australian archaeology departments in its philosophy and methodology. This, and the four fi eld approach used in UQ, in turn produced several generations of scholars who continue to influence archaeological thinking in this country and beyond.
Celebrated as a gifted teacher and a pioneer of Queensland archaeology, Jay leaves a rich legacy of scholarship and achievement across a wide range of archaeological endeavours. This volume brings together past and present students, colleagues and friends to celebrate Jay’s contributions, influences and interests. The theses included in the Bibliography embody a considerable amount of original research which is not available elsewhere.
The Bibliography is the result of a long-term project undertaken by the Aboriginal and Torres Strait Islander Studies Unit at the University of Queensland to collect, abstract and index theses with Indigenous Australian content, which were accepted for a degree at the University of Queensland. The project was initiated in response to a perceived need to make the results of postgraduate research available not only to internal and external researchers but also to Aboriginal and Torres Strait Islander communities.
University of Queensland theses with Aboriginal and Torres Strait Islander content have been included in several other thesis bibliographies and lists e. Coppell ; Hall ; White , However, these listings are either dated or discipline-specific and do not cover the full range of theses completed at the University of Queensland. More comprehensive searches were therefore carried out using the University of Queensland Library catalogue, supplemented by manual searches of departmental thesis collections and checked against entries in the Australian Institute of Aboriginal and Torres Strait Islander Studies Library catalogue.

Share 1 Stone tool assemblage recovered from the Gault Site. For decades, researchers believed the Western Hemisphere was settled by humans roughly 13, years ago, a theory based largely upon the widespread distribution of Clovis artefacts dated to that time. Clovis artefacts are distinctive prehistoric stone tools so named because they were initially found near Clovis, New Mexico, in the s but have since been identified throughout North and South America.
Significantly, this research identifies a previously unknown, early projectile point technology unrelated to Clovis, which suggests that Clovis technology spread across an already well-established, indigenous population. The presence of Clovis technology at the site is well-documented, but excavations below the deposits containing Clovis artifacts revealed well-stratified sediments containing artefacts distinctly different from Clovis.
To determine the ages of these artefacts, Rodrigues, Keen-Zebert, and colleagues used a process called optically simulated luminescence OSL dating to the ages of the surrounding sedimentary material.

The tropical karstic region of Lagoa Santa, in central Brazil state of Minas Gerais is one of the richest bioanthropological records available to study the behaviors and funerary practices of early Holocene South Americans, with more than skeletons found so far. One of the key locations to examine the history of human settlement in Lagoa Santa is the site of Lapa do Santo, a rockshelter known to contain the oldest rock art and the earliest evidence of funerary complexity in the continent.
In this geoarchaeological investigation we focus on the early Holocene settlement at Lapa do Santo 7. This is the first time that a micro-contextual approach integrated with experimental geoarchaeology has been applied to study the formation of rockshelter deposits in a tropical setting. Our results show that the stratigraphic sequence formed under the dual influence of anthropogenic sedimentationdthrough continuous combustion activitiesdand geogenic sedimentation in the form of oxisol aggregates which fell from above the limestone cliff into the rockshelter.

Sedimentology, palynology and geochronology have been integrated within ongoing archaeological investigations to reconstruct the Holocene palaeoenvironmental history of the Seille Valley and to elucidate the human-environment relationship of salt production. A sedimentary model of the valley has been constructed from a borehole survey of the floodplain and pollen analyses have been undertaken to reconstruct the vegetation history.
Alluvial records have been successfully dated using optically stimulated luminescence and radiocarbon techniques, thereby providing a robust chronological framework. The results have provided an insight into the development of favourable conditions for salt production and there is evidence in the sedimentary record to suggest that salt production may have taken place during the Mid-to-Late Bronze Age. The latter has yet to be identified in the archaeological record and targeted excavation is therefore underway to test this finding.
The development of the Iron Age industry had a major impact on the hydrological regime of the valley and its sedimentological history, with evidence for accelerated alluviation arising from floodplain erosion at salt production sites and modification of the local fluvial regime due to briquetage accumulation on the floodplain. This research provides an important insight into the environmental implications of early industrial activities, in addition to advancing knowledge about the Holocene palaeoenvironmental and social history of this previously poorly studied region of France.
These have been challenged by recently discovered archaeological sites in north Southwark. Reinvestigation of this area is therefore required. There is also a pressing need for an effective predictive model capable of locating prehistoric archaeological sites in Central London. These issues are addressed here. Surface topography, peat development, vegetation and archaeology are considered. This is supplemented by detailed pollen and lithostratigraphic investigation of Tabard Square in north Southwark.
Use of luminescence dating in archaeology
Stratigraphic unit numbers are shown on the left, and the cultural horizons are highlighted in gray. Clovis ages have been reported elsewhere see text. No HF etching was applied. An initial equivalent dose De estimate was made by comparing the natural OSL signal of four aliquots to their OSL signal after a given dose.
Luminescence dating has a proud history of association with archaeology, beginning almost half a century ago. The subsequent decades of research have seen a range of archaeometric applications of luminescence dating: from fired pottery and burnt flints to sediments incorporated into occupation deposits and earthen constructions.
Paul manages our GIS and Cartography group, providing insight and adding value to the vast amounts of information necessary for project success. Monitoring Cultural Resources Monitoring Far Western provides two types of monitoring—construction and site assessment. Construction monitoring consists of an archaeologist—often together with a Native American representative—observing the construction phase of a project to ensure that cultural resources are not inadvertently damaged or destroyed.
We have monitored everything from small local building projects to major power and gas line installations, usually in consultation with Native tribes and government agencies. Big or small, these projects can have tight schedules, and Far Western works closely with construction personnel to keep things on track. For site assessment monitoring, our archaeologists visit known cultural sites, often over a period of several years, to assess their physical condition and document any new or ongoing impacts that need to be addressed.
Such monitoring is often a requirement for federal permits or funding. Public Outreach and Interpretation Public Outreach and Interpretation One of our particular talents is the design and production of broadcast-quality films, interpretive signs, brochures, training manuals, and other educational and outreach products. These often serve as mitigation for projects where adverse effects to significant archaeological or historical resources are unavoidable. Our highly skilled team will research and write content; supply original paintings, illustrations, photographs, and maps; and track down archival images, to make our educational and outreach products truly compelling.
