76-100 (187 Records)
This is an abstract from the "Novel Statistical Techniques in Archaeology II (QUANTARCH II)" session, at the 84th annual meeting of the Society for American Archaeology. Archaeological surveys using GNSS receivers (Global Navigation Satellite System) to register artefact location generally state the accuracy of used devices, but rarely discuss the precision of resulting data. In other words, we have an idea of how "true" individual points are, but not as much regarding the statistical...
Identifying Archaeological Dacite and Andesite Sources in Southeastern Colorado (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. Widely utilized raw stone material common in archaeological sites in southeastern Colorado has been determined to be a combination of dacite and andesite.

Archaeological dacite and its sources...
Identifying Source Deposits in Monticello’s South Pavilion (2018)
During the winter of 2016, archaeologists excavated the interior of Monticello’s South Pavilion in advance of restoration. The South Pavilion’s basement served as the original kitchen until 1808, when it was connected to the main house via the South Dependency Wing and repurposed into a wash house. In order to level the floors between the South Pavilion basement and the new, immediately adjacent wing, Thomas Jefferson’s enslaved laborers used three feet of sediment to raise the basement floor....

Late Pleistocene and Early Holocene Lake-Level Fluctuations in the Lahontan Basin, Nevada: An Expanded Approach (2018)
In the Great Basin, most substantial Paleoindian sites are found on landforms associated with extinct lakes and wetlands, suggesting that early groups had a special affinity for lacustrine settings. The Lahontan Basin of western Nevada contains a rich record of Terminal Pleistocene and Early Holocene (TP/EH) lake-level fluctuation and an extensive record of Paleoindian occupation. In 2008, Ken Adams and colleagues compared the relationship between site location and lakeshores of known ages using...
Lead Isotope Analysis of Bronze Bells from Spanish Colonization Era (2018)
This study focuses on using analytical techniques, such as Multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) and X-ray Florescence (XRF), to determine lead isotope levels of bronze bells from the Spanish colonization era within South Carolina and New Mexico. These values are compared both against one another geographically and against ore isotopic data within regional and possible imported geographic regions. The goal is to both discern whether these bells are locally...
