Middle and Upper Cambrian rocks and locally up to 90 feet of Lower Ordovician rocks in Central Texas, are here named the Moore Hollow Group. In ascending order, the Moore Hollow Group is composed of the Riley Formation (Hickory Sandstone, Cap Mountain Limestone, and Lion Mountain Sandstone Members) and the Wilberns Formation (Welge Sandstone, Morgan Creek Limestone, Point Peak, and San Saba Members).

Annual report for the Bureau of Economic Geology 1977

The objectives of this symposium [were] (1) to bring together individuals from universities and industry who have conducted research on Cretaceous carbonates, in order to accelerate communication, exchange ideas, and discuss differences of opinion; (2) to emphasize subsurface carbonate studies but to include outcrop investigations which provide insight into interpreting the subsurface; (3) to cover all aspects of carbonate studies--regional geological setting, facies and depositional environments, paleontology, and diagenesis.
