The PIs will investigate the relationships between Late Paleozoic remagnetization deformation, and diagenesis, by studying the rock magnetic properties and deformation microstructures in Paleozoic carbonates from a number of localities in eastern North America. The principal goals will be to: 1) more completely characterize the magnetic mineralogy and remanence carriers in remagnetized carbonate strata; 2) investigate possible quantitative correlations between diagenetic illite and diagenetic/authigenic magnetite content; 3) compare the orientations and magnitudes of magnetic and calcite twinning strain fabrics; and 4) evaluate the connections between Late Paleozoic fluid migration, calcite twinning, and magnetite authigenesis, and the evolution of the Appalachian-Ouachita fold- and-thrust belt.
