15 صفحه اول40Ar/39Ar geochronology of the Eocene Green River Formation, Wyoming
The deposits of Eocene Lake Gosiute that constitute the Green River Formation of Wyoming contain numerous tuff beds that represent isochronous, correlatable stratigraphic markers. Tuff beds selected for 40Ar/39Ar analysis occur within laminated mudstone, are matrix supported, and lack evidence of reworking. These tuffs contain 2%–15% euhedral phenocrysts of quartz, plagioclase, sanidine, biotit...

متن کاملSalamander Tracks (ambystomichnus?) from the Cathedral Bluffs Tongue of the Wasatch Formation (eocene), Northeastern Green River Basin, Wyoming
VERTEBRATE TRACKS are comparatively rare in Tertiary deposits of the western United States. Unlike the deposits of the Mesozoic in this region, in which each formation often has several dozen known tracksites, there are only a few known sites in Paleocene units of the region (Lockley and Hunt, 1995), and though the Eocene Green River Formation contains relatively numerous tracks, especially tho...
متن کاملDiscussion and reply: 40Ar/39Ar geochronology of the Eocene Green River Formation, Wyoming Discussion
Smith et al. (2003, hereafter referred to as Smith et al.) present seven new isotopic ages from the Green River Formation in the greater Green River Basin. These data provide welcome new information in the ongoing effort to develop a coherent and reliable geochronological framework for this large and stratigraphically complex basin. Several of their main conclusions are based on a revised age e...
