One of the original 13 states of the USA. A state with diverse geology ranging from Precambrian regions in the easternmost areas, vast beds of dolomitic limestones, Pennsylvanian period formations containing both anthracite coal (eastern) and bituminous coal (western). Triassic diabase intrudes older rocks along the eastern border and into the center of the state.
