Electronic Theses, Projects, and Dissertations
This research evaluates the extent of ceramic shrinkage using a natural clay source that was locally available and known to be used by native populations in the American Southwest. The experiment took into account variables of temper mixture and firing temperature to assess the extent and potential need for shrinkage calibration in archaeological biometric research (specifically fingerprints). An experimental design was employed to test shrinkage rates while accounting for natural temper materials found frequently in the archaeological record including sand, grog, and quartz. The experiment evaluated whether shrinkage rates may have skewed data collected in previous studies regarding sex and …

Graduate Research Theses & Dissertations
Magmatic-hydrothermal ore deposits contain metals sourced from a melt and transported to shallower levels by a magmatic volatile phase (MVP) where they can be deposited as native elements or structurally bound in sulfide or oxide minerals. Porphyry ore deposits are a major subclass of such and contain plentiful concentrations of societally significant metals including copper and gold. These deposits include the Grasberg porphyry Cu-Au-(Mo) deposit in Indonesia, the Bingham Canyon porphyry Cu-Mo-Au deposit in Utah, USA, and the Far Southeast porphyry Cu-Au deposit in the Philippines. In these systems gold is often found associated with bornite, intermediate solid solution (ISS, …
