Palynology of the upper Pennsylvanian Dalton coal, Palo Pinto county, texas, U.S.A

Autor: Judith A. Gennett, Robert L. Ravn

Publikováno v: Palynology. 17:115-122

The Dalton Coal of north‐central Texas yields a palynomorph assemblage characteristic of basal Late Pennsylvanian (Stephanian) coals from the Midcontinent U.S.A., and also indicative of an allochthonous origin for the greater part of the seam. The

A late quaternary pollen sequence from blacktail pond, Yellowstone national park, Wyoming, U.S.A

Autor: Richard G. Baker, Judith A. Gennett

Publikováno v: Palynology. 10:61-71

The pollen record at Blacktail Pond provides evidence for the vegetational development of the lowest and driest site yet reported in Yellowstone National Park (elev. 2,018 m). The record begins shortly after deglaciation, over 14,000 yr B.P. (before

Oxygen and Carbon Isotope Trends in a Late Glacial-Holocene Pollen Site in Wyoming, U.S.A

Autor: Judith A. Gennett, Ethan L. Grossman

Stable isotope studies of North American Late Glacial and Holocene lake sediments are few. Previous studies of pollen sites in Indiana, South Dakota, and the Great Lakes area show low δ18O values during deglaciation, rising to a Hypsithermal peak, a
