Pottsville series of upper carboniferous age
WebThere are: Cracow Sandstone Series (Westphalian B-D), Upper Silesian Sandstone Series (Namurian B-C), Siltstone Series (Westphalian A, lower Westphalian B) and Paralic Series (Namurian A). Carboniferous aquifers represented by sandstones, partly siltstones, have a thickness ranging from 0.5 to more than several dozen meters. Web3 Jul 2006 · A projected age of 312 Ma is here suggested for the age of this coal bed based on stratigraphic thickness and assuming a near-constant rate of deposition. Thus, the Middle Pennsylvanian in the central Appalachian basin as well as the period of explosive volcanic activity lasted 4 ± 2 Ma.
