CHANGES IN OBSIDIAN SUPPLY DURING THE CLASSIC TO POSTCLASSIC TRANSITION IN PREHISPANIC PUEBLA-TLAXCALA (2016)
DOCUMENT Citation Only Aurelio Lopez Corral. Mari Carmen Serra Puche. Gabriel Vicencio Castellanos.

The Puebla-Tlaxcala region witnessed several shifts in political and economic power during the Classic to Postclassic transition. This area played a pivotal role in the development of cultural complexity following the demographic rearrangements that followed the fall of Teotihuacan as a pan-regional state power. However, little research has been carried on understanding shifts in exchange networks, especially on the trade of obsidian materials. Using XRF-p analysis, this paper seeks to provide...

ITRAX XRF analysis of shell midden sediments from sites on the central coast of British Columbia (2017)
DOCUMENT Citation Only Kari Carter. Aubrey Cannon. Eduard Reinhardt.

We present the results of using an ITRAX XRF core scanner on fine-fraction shell midden sediments. High-resolution multi-element analyses of central coast sites confirm patterned intra- and inter-site variability in the relative abundance of phosphorus and calcium determined on the basis of earlier low-resolution studies. Analysis of Namu site deposits dating from 11,000-2000 cal BP show the relative absence of residual calcium in early shell-free deposits (ca. 11,000-7000 cal BP) but overall...

ORGANIC RESIDUE (FTIR) AND ELEMENTAL COMPOSITION (pXRF) ANALYSIS OF ROCK ART PIGMENT FROM SENTINEL BLUFF ROCKSHELTER, TEHAMA COUNTY, CALIFORNIA (2014)
DOCUMENT Full-Text Jennifer L.B. Milligan. Linda Scott Cummings.

Sentinel Bluff Rockshelter is situated along the western edge of Turtle Creek in Tehama County, California. On an interior wall of the rockshelter are two negative hand pictographs created with a maroon-colored pigment that appears to have been “sprayed” around the hands. A small sample of the pigment was collected for elemental composition (pXRF) and organic residue (FTIR) analysis to determine whether the paint was made using organic compounds, mineral compounds, or a combination of the two....

DOCUMENT Full-Text Linda Scott Cummings. Jennifer L.B. Milligan. Cody Dalpra.

The Ferguson site (3HE63) is a two acre multi-component Caddo mound site in Hempstead County, southwestern Arkansas. It is adjacent to Caruse Creek within the Little Missouri River drainage. The Ferguson site was first recorded by the Arkansas Archaeological Survey in 1971 and was excavated between 1972 and 1974. These excavations revealed two Caddo mounds, a Fourche Maline midden, a small Caddo and Fourche Maline cemetery area, and an underlying Dalton and early Archaic component (Chowdhury...


Over the mountains and through the desert: obsidian use, procurement, and transportation in Northwest Colorado (2017)
DOCUMENT Citation Only Sarah MacDonald. Brian Yaquinto.

Obsidian is a rare raw material in northwest Colorado. As no naturally occurring sources have been identified in the region, obsidian artifacts recovered at archaeological sites were likely brought in through exchange or direct procurement during seasonal foraging routes. Using X-ray fluorescence (XRF) analysis to identify obsidian sources, this poster addresses three questions related to obsidian artifacts found in the Colorado Bureau of Land Management, White River Field Office (WRFO): what...

Six lithics from the artifact assemblage were submitted for protein residue, and elemental composition (X-ray...


The Role of Bronze Age People in the Post-Bronze Age Landscape: An Integrated Geoarchaeological Approach to Site Formation at Mycenae, Greece (2016)
DOCUMENT Citation Only Daniel Fallu. Justin Holcomb.

While human-landscape interaction has been a key question in the archaeology of early complex societies, little research has focused on the effect of occupation on the landscape post-abandonment. At Mycenae, a Late Bronze Age citadel in southern Greece, two distinct deposits, one anthropogenic and one natural, were identified as covering archaeological remains dating to the 12th century, B.C. Here, we present an integrated method combining micromorphology, Fourier Transform Infrared (FTIR), and...

DOCUMENT Full-Text Angela McArdle.

This paper examines an obsidian cache offering excavated near the corner of a Postclassic Maya platform structure in Nojpeten, on the island of Flores, Guatemala. The cache consists of approximately 190 obsidian prismatic blade cores and core fragments, but the original number of cores placed in the cache likely fell between 173 and 182, with a best estimate of 177, 178, or 180. The cores were found about 20 cm southwest of the structure in a circular concentration measuring approximately 35 cm...
