Final Report: "The GIAR funds were used to partially support a new collaborative project between UW-Green Bay (myself and student Alex Edler), Alyssa Shiel (University of Illinois), and Jared Freiburg (Illinois State Geological Survey). The purpose of the project was to determine whether or not crystals of the mineral calcite (CaCO3), found throughout parts of Wisconsin, northern Illinois, and northeastern Iowa, are related to the same ancient groundwater flow system. The research involved three major types of chemical analyses of several calcite crystals: 1) the trace element chemistry, 2) the 87Sr/86Sr isotopic composition, and 3) the ∂18O and ∂13C isotopic composition of specific growth zones in these calcite crystals. The trace element and isotopic composition of these crystals is a product of the chemistry of the fluids responsible for precipitation of the minerals. The results of our project have been successful in demonstrating that indeed some of the calcites in the region appear related to the same ancient groundwater source. Others show distinctly different chemical and isotopic compositions, suggesting the possibility of a second source of fluids. A new collaborator, Troy Rasbury (Stony Brook University), has agreed to attempt uranium-lead isotopic age dating techniques on these samples to further aid in assessing whether the crystals are of the same or different ages. Our samples are currently in the queue and we hope to receive those results during Spring 2014. We believe that the results of our work will be publishable. Data analysis is ongoing as we wait to see the results of age dating analysis. Our plan is to submit a manuscript to a peer-reviewed journal during summer 2014."
