New Planktic Foraminiferal Data Documenting Coniacian Age For Laramide Orogeny Onset and Paleooceanography in Southern Mexico
Autor: Harold R. Lang, William E. Frerichs
Publikováno v: The Journal of Geology. 106:635-640
A Late Cretaceous flysch comprising the 2600‐m‐thick Mexcala Formation records the initial local pulse of the Laramide Orogeny on the southern arm of the Mexican fold‐thrust belt in northeastern Guerrero State. We identified 15 planktic foramin

Distinguishing middle Late Cretaceous tectonic events from regional sea-level change using foraminiferal data from the U.S. Western Interior
Autor: William E. Frerichs, Virginia S. Martinson, Paul L. Heller
Publikováno v: Geological Society of America Bulletin. 110:259-268
Foraminiferal data from seven stratigraphic sections between the Utah-Wyoming thrust belt and western Kansas record 13 correlatable paleoecologic events between Coniacian and early Campanian time, and provide a framework for interpreting tectonic tim

Paleomagnetism of the Niobrara Formation in Wyoming, Colorado, and Kansas
Autor: William E. Frerichs, Peter N. Shive
Publikováno v: Journal of Geophysical Research. 79:3001-3007
None of the approximately 350 samples collected from the Upper Cretaceous Niobrara formation in Wyoming, Colorado, and Kansas are reversely magnetized. Of these, 109 are completely oriented samples from limestone and chalk units; the remainder are sh

Mesozoic Planktic Foraminifera
Autor: William E. Frerichs
Publikováno v: Notes for a Short Course: Studies in Geology. 6:148-162
The evolutionary development of Mesozoic planktic foraminifera is almost exclusively restricted to the Cretaceous Period. Diversity is relatively low until the Late Cretaceous (Turonian to Maastrichtian) when numerous architectural forms are found in

Tectonic implications of variations in sea floor spreading rates
Autor: Peter N. Shive, William E. Frerichs
Publikováno v: Earth and Planetary Science Letters. 12:406-410
Changes in sea floor spreading rates and directions are related in time to periods of worldwide uplift indicating that sea floor spreading episodes and tectonic cycles may be driven by the same basic mechanism.
