A Comparative Rockmagnetic and Calcite Strain Study of Deformation, Diagenesis, and Remagnetization of Paleozoic Cratonic Carbonates

PI将调查Late与 古生代再磁化变形和成岩作用， 研究岩石的磁性和变形 一些古生代碳酸盐岩的显微结构 北美东部的一些地方。 主要目标将是 为了：1）更全面地表征磁性矿物学， 重磁化碳酸盐岩地层中的剩磁载体; 2） 研究成岩作用之间可能的定量关系 伊利石和成岩/自生磁铁矿含量; 3）比较 磁性和方解石孪晶的方向和大小 应变组构;和4）评估晚 古生代流体运移、方解石孪生和磁铁矿 阿巴拉契亚-沃希塔褶皱的演化 逆冲断层带

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.
