Abstract

Pre-Quaternary hillslope records provide a physical link between the source of sediment on hillslopes and the sedimentary sink of depositional basins. This guide complements a field excursion to localities in the Panaca and Table Mesa basins of southeast Nevada that are related to study of this unusual type of sedimentary deposit. Study of the sedimentology and stratigraphic context of this “ancient colluvium” provides new information on climate controls on sedimentation and landscape dynamics in this dry setting. Topics addressed herein include the stratigraphy, age, depositional environment, provenance, and paleontology of late-stage basin fill of the Muddy Creek and Panaca Formations; rock-type versus climate controls on sediment yield; and the landscape evolution of the region. Below we provide a background to the research problems addressed along with the general geologic setting and history, then follow with descriptions and research results associated with each of the two days of the field trip.
