Driese, S.G., Mora, C.I., and Cotter, Edward, 1993, Nesopeck Creek paleosol, Mauch Chunk Formation near Nescopeck Creek, Pennsylvania, IN Driese, S.G., ed., Paleosols, paleoclimate and paleoatmospheric CO2; Paleozoic paleosols of central Pennsylvania: University of Tennessee, Department of Geological Sciences Studies in Geology, no. 22, p. 91-102.


Summary:

Mauch Chunk stratigraphy at this locality is characterized by repetitively stacked, 2- to 5-m-thick fining upward sequences characterized by alternation of non-red sandstones and red siltstones and mudstones containing paleosols and pedogenic carbonate. Sandstones have been interpreted as meandering stream deposits and the mudstones and siltstones as floodplain deposits. The Nescopeck paleosol occurs in the basal 3 m of the measured section and includes three distinct horizons: calcrete, slickensided silty claystone, and root-mottled siltstone. Soil is erosively truncated by non-red, cross-bedded channel sandstone. Age of the Mauch Chunk and its Nescopeck paleosol is Late Mississippian. [Though soil is referred to as Nescopeck Creek paleosol in the title, it is called simply Nescopeck throughout the text.]
