The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

A combined visual-geochemical approach to establishing provenance for pegmatite quartz artifacts and application within the Churchill River basin of Manitoba and Saskatchewanten Bruggencate, Rachel E. 16 September 2013 (has links)
This dissertation aims to provide insight into the relationships between environmental
factors and the organization of quartz technology in northern Manitoba by evaluating the
contribution of large pegmatite quarries to quartz economies around Granville and
Southern Indian Lakes. Secondary ion mass spectrometry (SIMS) quantification of trace
element (Ti, Ge, U, Th) concentrations and Pb isotope ratios was used to characterize
large sources of pegmatite quartz exploited by toolmakers in the Granville Lake and Lac
La Ronge regions of northern Manitoba and Saskatchewan, respectively. The same
technique was applied to a sample of formal quartz tools from the Churchill River
Diversion Archaeological Project (CRDAP) study area in northern Manitoba. Quarry and
artifact results were compared. The results of this analysis indicate: 1) characterized
pegmatite quartz sources in the Granville Lake district likely played a significant role in quartz economies in the Churchill River basin of northern Manitoba, 2) toolmakers in the study area had large lithic procurement ranges, and 3) lithic resource stress contributed to the selection of technological strategies in the Churchill River basin.
