【 摘 要 】

This paper reviews previous work conducted on Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) sourcing 33 Clovis period projectile points from the Gault Site (41BL323) in Central Texas. This paper includes new geochemical data from four new primary geologic sources to increase an Edwards Plateau region chert database to 302 primary geologic samples from 204 samples with which to test against the geochemistry of the 33 Clovis artifacts. These artifacts are then assessed with regards to their form, breakage patterns, and distance to source to suggest a blended model of mobility for Clovis period hunter-gatherers in Central Texas. This data suggests that the pattern of movement across the landscape of the Edwards Plateau for these hunter-gatherers may have been a blended pattern alternating between collector and forager based on changing distribution of resources seasonally. This patterning may have been influenced for the Gault Clovis hunter-gatherers reliant on availability of chert resources as well as ecotonal density and diversity of plants and animals; especially, as gauged by Clovis site types and distribution spread throughout much of the Southern Great Plains.
