Implications Of Thermal Events On Thrust Emplacement Sequence In The Appalachian Fold And Thrust Belt: Some New Vitrinite Reflectance Data, Sharon E. Lewis, James C. Hower

Center for Applied Energy Research Faculty and Staff Publications

Interpretation of existing geothermometry data combined with new vitrinite reflectance data, within the framework of a detailed composite tectonic setting, elucidates the evolution of structural sequencing of thrust sheets during the Alleghanian event in the Valley and Ridge Province in Virginia. That the Pulaski thrust sheet preceded the Saltville thrust sheet in the emplacement sequence, and that both reached thermal maxima prior to, or during, respective emplacement may be inferred from vitrinite and other geothermometry data. In contrast, the Narrows and St. Clair thrust sheets probably each attained their thermal maximum after emplacement. New vitrinite reflectance data are consistent with …
