B03-T: A Microanalytical and Petrochemical Approach to Investigating Megacrystic Feldspar Crystallization, CA

Crystal-rich, chemically evolved, coarse-grained igneous rocks provide opportunities to investigate the differentiation and solidification of magmas within Earth’s crust. Specifically, by investigating the micro-scale textural, chemical, and chronological record of these crystal populations insights into the processes which operated during magmatic crystallization and intrusion of large magma bodies within Earth’s crust can be evaluated. This […]

B02-T: Utilization of Remote Sensing to Identify Brownfields

Recognizing brownfield prevalence in the United States and globally, researchers strive to better understand brownfields and their climate implications. A brownfield is defined as a property that has a complicated redevelopment or reuse process because of potential hazardous substances, pollutants, or contamination present at the site (EPA 2012). There is a need for brownfield identification […]

B01-T: Assessment of the Radiocarbon Reservoir Effect in Modern Aquatic Gastropod and Bivalve Shells of Four Mile Creek, Ohio

Radiocarbon reservoir effects occur when organisms incorporate carbon that is not in equilibrium with the modern atmosphere. These reservoir effects often result in 14C ages of fossils shells that are too old, often by thousands of years. Dissolution of limestone bedrock in southwestern Ohio may lead stream water to be enriched in old, dissolved carbon […]

B05-T: Mineralogy of Hicks Dome Breccias, Southern Illinois

The Illinois-Kentucky Fluorspar District (IKFD) represents a fluoritic subclass of Mississippi Valley-Type deposits (MVT), which are low-temperature lead-zinc ore deposits formed by hydrothermal fluids. Typically MVTs lack contribution from and do not occur near igneous activity. However, due to a cryptoexplosive feature, surrounding Hicks Dome are numerous mafic and ultramafic igneous intrusions, most of which […]
