3-Dimensional Mapping of Hydrous Impurities in a Single Quartz Crystal Sampled at Windgallenhutte, Switzerland
Wipperfurth, Scott A.; Johnson, Aleisha C.; Lindblad, Todd A. (2014-04)The spatial distribution of chemical impurities in gemmy quartz reveals the thermal evolution of their host hydrothermal fluids and documents syn- and post-crystallization chemical diffusion. The purpose of this study was ... -
Characterization of 18th Century French Glass from Saint-Nicolas-des-Biefs, Auvergne-Rhone-Alpes, France : Chemistry and Infrared Spectroscopy
Vang, Duabchi; Anderson, Jackelyn R.; Langfield, Katherine; Ihinger, Phillip D. (2019-05)Glass beads manufactured in Europe were brought to North America and used in trade with native American peoples. The style and composition of glass beads can be used to trace intercontinental connections between the 16th ... -
Characterization of 18th Century French Glass Trade Beads from Fort Mackinac, MI : Chemistry and Infrared Spectroscopy
Vang, Duabchi; Anderson, Jackelyn R.; Langfield, Katherine; Ihinger, Phillip D. (2019-05)Glass trade beads made in Europe were an important commodity in colonial North America. The style and composition of glass beads were unique to each manufacturing site and can be used today to trace trading relationships ... -
Chemical Diffusion in Watermelon Tourmaline : Parallel Versus Perpendicular to C-axis
Tollefson, Kyle; Ihinger, Phillip D. (2018-02-09)The chemical composition of tourmaline can provide unique insights into the thermal evolution of their growth environment, including that of pegmatites (in igneous systems) and hydrothermal veins (in metamorphic systems). ... -
Chemical Effects of Glass Hydration in the Natural Environment
Conde, Giselle (2012-04)The hydration of glass is of great interest to industry, archaeology, and geology. Molecular water species react with silicate bonds to form hydroxyl species that allow for rapid exchange of elements into and out of the ... -
Chemical Fingerprint of Quartz Crystals Sampled Across the Lepontine Zone in the Swiss Alps
Wipperfurth, Scott A.; Johnson, Aleisha C.; Lindblad, Todd A. (2013-05)Quartz crystals record the evolution of hydrothermal fluid systems that accompanied the uplift of the Swiss Alps. Crystals from twenty localities were collected along a geologic traverse across four distinct temperature ... -
Chemical Fingerprint of Quartz Crystals Sampled at Windgallenhutte, Switzerland
Johnson, Aleisha C.; Wipperfurth, Scott A.; Lindblad, Todd A. (2013-05)The spatial distribution of chemical impurities in hydrothermal quartz crystals documents the evolution of their host hydrothermal fluids and offers potential insights into their post-crystallization thermal histories. ... -
Color in Watermelon Tourmaline : The Role of Hydroxyl Diffusion
Ihinger, Phillip D.; Tollefson, Kyle (2018-05)Tourmaline is a semiprecious gemstone known in the geologic community known for its complex chemical formula. This is because the crystal structure of tourmaline can incorporate and contain numerous elements from the ... -
Competing Diffusion Pathways in High-Temperature Metamorphic Quartz
Fitzpatrick, William A.; Brinza, Eric M.; Ihinger, Phillip D. (2018-03-05)We present spectroscopic analyses that characterize the distribution and abundance of hydroxyl-bearing impurities within a single quartz crystal grown in hydrothermal fluid. We focus on a gemmy quartz crystal collected in ... -
Computer Simulations of Magma Chamber Evolution : Testing an Alternative Model for the Development of Layered Mafic Intrusions and the Origin of Granite
Spencer, Christopher B. (2010-04)The association of granite and basalt is observed in every large basaltic magma chamber. Large basaltic rock bodies (termed LMIs, for Layered Mafic Intrusions) provide unique insights into the evolution of the material ... -
Computer Simulations of Magma Chamber Evolution : Testing an Alternative Model for the Development of Layered Mafic Intrusions and the Origin of Granite
Spencer, Christopher B. (2011-05)The association of granite and basalt is observed in every large basaltic magma chamber. Large basaltic rock bodies (termed LMIs, for Layered Mafic Intrusions) provide unique insights into the evolution of the material ... -
Constraining Late Cretaceous Magmatic Evolution in Southwestern Montana.
Guy, Alexandra K. (2009-01-23)The Elkhorn Mountains volcanics (EMV) of southwest Montana comprise Late Cretaceous andesitic to rhyolitic tuffs and flows that are adjacent to and coeval with the Boulder batholith (Bb) and it satellite intrusions (Si). ... -
Controlled Pressure-Temperature Cycling in Rapid-Quench Cold-Seal Experimental Apparatus
Wipperfurth, Scott A.; Stuntz, Gabriel T. (2014-04)Externally heated rapid-quench cold-seal pressure vessels can maintain temperatures up to 1000 Celsius and pressures up to 2.0 kbars. These conditions simulate shallow felsic magma chambers, as well as most metamorphic ... -
Determination of Chemical Composition of Red Lithic Artifacts Using X-Ray Fluorescence
Bender, Shiloh A. (2011-05)This research project analyzed the geochemistry of pre-contact American Indian artifacts from western Wisconsin using Handheld X-Ray Fluorescence (XRF). XRF will determine the distinct chemical composition of the ... -
Detrital Zircon Evidence Requires Revision of Belt Stratigraphy in Southwest Montana.
Balgord, Elizabeth A.; Forgette, Michelle M.; MacLaurin, Catherine I. (2009-07-23)The Belt Supergroup was originally named for widespread exposures of thin-bedded red clastic strata in the Big Belt Mountains in southwestern Montana. Subsequent studies extended the geographic extent and thickness of the ... -
