content: Schoharie/Esopus Chert is also known as Bowmanstown, Carbon County Black, or Esopus. It is a gray, gray-black, or black cherty siltstone or silicified shale. It sometimes has waving banding. There is insignificant color chan when heat-treated. When weathered it becomes almost white. It has drusy quartz inclusions and a smooth, opaque texture. Deposits occur predominantly in deeply weathered fossiliferous, partly cherty siltstone and fine-grained sandstone. Deposits also include residuum as angular, tabular pieces 8"-10" in talus slope.
