Sedimentary facies and depositional environments of early Mesozoic Newark Supergroup basins, eastern North America
J. P. Smoot
1991, Palaeogeography, Palaeoclimatology, Palaeoecology (84) 369-423
The early Mesozoic Newark Supergroup consists of continental sedimentary rocks and basalt flows that occupy a NE-trending belt of elongate basins exposed in eastern North America. The basins were filled over a period of 30–40 m.y. spanning the Late Triassic to Early Jurassic, prior to the opening of the north...

Lynn J. Torak, G. S. Davis, George A. Strain, Jennifer G. Herndon
1991, Open-File Report 91-52
In the Albany area of southwestern Georgia, the Upper Floridan aquifer lies entirely within the Dougherty Plain district of the Coastal Plain physiographic province, and consists of the Ocala Limestone of late Eocene age. The aquifer is divided throughout most of the study area into an upper and a lower...
Hydrogeology and simulation of ground-water flow in the Rochester area, southeastern Minnesota, 1987-88
G. N. Delin
1991, Water-Resources Investigations Report 90-4081
Ground-water flow in the St. Peter-Prairie du Chien-Jordan aquifer was studied in a 700 square-mile area surrounding Rochester, Minnesota. The aquifer consisting of sandstone, limestone, and dolomite is locally confined by the Decorah-Platteville-Glenwood sequence of shales and limestones. Regional flow in the aquifer is from a ground-water divide on the...
