Sevier orogeny timing
Webin a complex lake system in present-day Wyoming, Colorado and Utah during the Laramide Orogeny (Dickinson et al., 1988; Smith et al., 2008). Lacustrine deposits of the Piceance Creek and Uinta basins accumulated in a large and long-lived lake, called Lake Uinta (e.g. Johnson et al., 2010; Tänavsuu-Milkeviciene & Sarg, 2012). WebThe earliest events associated with the Sevier orogeny are as early as 160 Ma (even before the Nevadan) and the latest deformation was 50 million years ago. However, the majority …

The Elko orogeny (Thorman et al., 1990, 1992) is so named because much of the evidence for the age of deformation is in Elko County.
WebThe Sevier orogeny lasted from about 119 Ma [Heller and Paola, 1989] to 50 Ma [DeCelles and Mitra, 1995] and resulted in displacement of thick plates of sedimentary rock eastward for tens of kilometers on bedding-plane thrusts with west dipping ramps. The Laramide orogeny lasted from about Web2 Oct 2024 · The timing of the Laramide orogeny, and its impacts on the east-flowing drainage systems from the Sevier hinterland, has been the subject of research and argument for more than a century. This talk will address new age data obtained from zircons preserved in outcrop samples collected from Wyoming’s Great Divide and Hanna basins.
