This book was released on 2014 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Knox unconformity represents a major break in Paleozoic carbonate deposition in the Appalachian Basin. The development of the angular unconformity has been attributed to both regional tectonism and eustasy. Better understanding the timing of the Knox unconformity allows for correlation to study areas outside of the Appalachian Basin, which may be used to elucidate the relative impact of these processes. Current biostratigraphic constraint on the timing and duration of the unconformity in the Virginia and West Virginia study area is based on a sparse fossil record and places the duration of the unconformity at around 10 mya. This study uses [delta]13C and 87Dr/86Sr chemostratigraphy to refine this timing through correlation to a more complete section farther north near the axis of the basin in Maryland. 87Dr/86Sr chemostratigraphy demonstrates that deposition resumed no later than 462 mya, in the Cahabagnathus. friendsvillensis conodont Zone, and refinement by [delta]13C correlation indicates that deposition likely ensued in the early part of this zone. 87Dr/86Sr chemostratigraphy in this study also establishes the maximum age for the uppermost preserved Knox Group strata (in this study area) at 473 mya, indicating a maximum possible duration of the Knox Unconformity in Virginia and West Virginia at 11 mya.
