Rocks of Carboniferous age are exposed in the northwestern one-third of Arkansas; more than two-thirds of the exposed rocks are of Pennsylvanian age. The contact between Devonian and Carboniferous rocks in most of Arkansas must be paleontologically determined. The area that is now Arkansas received shallow- to deep-water marine deposits until the start of the Ouachita orogeny (middle Pennsylvanian). Most of the middle and all of the upper Pennsylvanian rocks have been removed by erosion. Sill-like lenses of soapstone-serpentine of possible late Pennsylvanian age are found in middle Ordovician rocks. Beds of volcanic tuff are present in upper Mississippian rocks. Hydrothermal quartz veins of late Pennsylvanian age are abundant in the Ouachita Mt. Commercial quantities of coal, natural gas, antimony, barium, manganese, mercury, zinc, lead, dimension stone, limestone, slate, and tripoli are present in Carboniferous rocks.
