Deep Water Sediments Adjacent To The Borden Siltstone Mississippian Delta In Southern Illinois Classic Reprint

Excerpt from Deep-Water Sediments Adjacent to the Borden Siltstone (Mississippian) Delta in Southern Illinois Rocks of early Valmeyeran age (mississippian) ex bibit four major, laterally adjacent, noncontemporaneous, nonintergrading lithologic aspects in southern Illinois. The Fern Glen Formation, Burlington Limestone and Keokuk Lime stone represent a crinoidal carbonate bank that stood west of and topographically above a deep-water basin. The Bor den Siltstone, Warsaw Shale, and Springville Shale repre sent parts of a delta that invaded and restricted the deep waterbasin and overrode the crinoidal bank. The Fort Payne Formation is a tongue-shaped body of dark-colored, cherty, impure limestone that partially filled the deep-water basin after the end of deltaic deposition. The Ullin Limestone is a new name proposed for the light-colored bryozoan-rich limestone that overlies the Borden and Fort Payne and filled topographic depressions left after Port Payne deposition ceased. The Salem Limestone is a shallow-water carbonate that overlies the lower Valmeyeran sequence. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
