Cross-strike structural discontinuities: tear faults and transfer zones in the central Appalachians of West Virginia
The structural characteristics of two cross-strike structural discontinuities (CSD's) in the central sedimentary Appalachians of West Virginia and Virginia were examined using limited field studies, structural cross sections, and gravity modelling. Detailed mapping and joint intensity studies were confined to the Valley and Ridge Middle Mountain syncline and adjacent Elkhorn Mountain anticline in Pendleton County, West Virginia where these structures are intersected by an extension of the Parsons CSD. A gravity profile across these structures was also surveyed and modelled. Two structural cross sections were constructed across the sedimentary Appalachians to compare structural features north and south along the length of the Parsons CSD. Additional cross sections north of both the Parsons and Petersburg CSD's were constructed to provide additional details on subsurface Valley and Ridge structure in West Virginia. Comparisons of the theoretical gravity with already existing observed gravity data were made along these and other previously published structural sections through the area. 48 figures, 16 tables.
