  • Wilkins Peak Member, Eocene Green River Formation, Wyoming, U.S.A
    Journal of Sedimentary Research, 2006, v. 76, 1197–1214 Research Article DOI: 10.2110/jsr.2006.096 HIGH-RESOLUTION STRATIGRAPHY OF AN UNDERFILLED LAKE BASIN: WILKINS PEAK MEMBER, EOCENE GREEN RIVER FORMATION, WYOMING, U.S.A. JEFFREY T. PIETRAS* AND ALAN R. CARROLL 1University of Wisconsin-Madison, Department of Geology and Geophysics, 1215 West Dayton Street, Madison, Wisconsin 53706, U.S.A. e-mail: [email protected] ABSTRACT: Lakes tend to respond noticeably to minor changes in sediment and water balance driven by climatic, tectonic, or geomorphic processes. This unique behavior of lacustrine basins can provide a high-resolution record of geologic processes within the continental setting, far from the globally averaged record of marine strata. The Wilkins Peak Member of the Eocene Green River Formation, in Wyoming, USA, is dominated by aggradation of repetitive sedimentary facies successions recording distinct lacustrine expansions and contractions. These lacustrine ‘‘cycles’’ consist of up to four successive facies associations: littoral, profundal–sublittoral, palustrine, and salt pan. Because they comprise disparate facies that may never have been simultaneously deposited in the basin, Wilkins Peak Member cycles are non-Waltherian successions that do not readily equate to any established sequence stratigraphic unit. The completeness of the stratigraphic record in the Wilkins Peak Member varies continuously across the basin. At least 126 cycles are present in the ERDA White Mountain #1 core near the basin depocenter, whereas only about one third as many are recognizable 53 km north, nearer to the basin margin. Cycle boundaries terminate northward by gradual amalgamation into palustrine facies, reflecting the interplay between varying lake levels and a south-dipping deposition gradient.

Munroe* Geology Department, Middlebury College, Middlebury, VT, USA Received 7 February 2014; Revised 7 May 2014; Accepted 28 May 2014 *Correspondence to: Jeffrey S. Munroe, Geology Department, Middlebury College, Middlebury, VT 05753, USA. E-mail: [email protected] ABSTRACT: A growing body of work is illuminating the importance of dust as a component of soil development and biogeochem- ical cycling in alpine environments of the Rocky Mountains. Nonetheless, important questions remain about the dust system in this region due to a paucity of focused studies and direct measurements. This project involved deployment of modified marble dust traps in the alpine zone of the Uinta Mountains of Utah to trap modern atmospheric dust over a two year period. Results indicate that dust accumulation rates are similar to values previously reported for the Wind River Range of Wyoming, but less than values for south- western Colorado, suggesting a south-to-north decrease in regional dust flux. The overall mean grain size of Uinta dust is similar to values reported by prior studies in Colorado, indicating a general uniformity in grain size distribution. Uinta dust is dominated by quartz, plagioclase, K-feldspar, and illite with trace amounts of kaolinite, chlorite, and amphibole. In contrast, only quartz and K-feldspar are present in the Uinta bedrock, confirming an exotic origin for the dust arriving in the alpine zone.

  • Stratigraphy of the Green River Formation in the Bridger Basin, Wyoming1
    THE OHIO JOURNAL OF SCIENCE VOL. 63 NOVEMBER, 1963 No. 6 STRATIGRAPHY OF THE GREEN RIVER FORMATION IN THE BRIDGER BASIN, WYOMING1 DANIEL A. TEXTORIS Department of Geology, University of Illinois, Urbana, Illinois INTRODUCTION This paper presents the results of a subsurface-surface stratigraphic study of the lacustrine Green River Formation and related strata in the Bridger Basin of southwestern Wyoming. Although the Green River Formation has been mapped in some detail, and several geologists have worked on the shore and near-shore facies in areas bordering the basin, no detailed subsurface study of the formation has so far appeared. The Diamond Alkali Co. No. 3 well was chosen as a type well since it displayed all the surface stratigraphic units in core or cuttings, and electric log. Surface sections and other wells were then correlated with it. PREVIOUS STUDIES Reconnaissance studies of the Green River Formation in the Bridger Basin began with the Territorial Surveys of Powell, Hayden, and King from 1868 to 1878. No detailed stratigraphic work was attempted until Schultz (1920) mapped the Rock Springs Uplift and adjacent areas. Green River nomenclature was ex- panded or revised by Sears and Bradley (1924), Bradley (1926, 1959, 1961), Donavan (1950), Deardorff (1959), and Culbertson (1962). Several geologists have studied the shore and near-shore phases of the Green River Formation. Donavan (1950) and Oriel (1961) worked on the northwest outcrop, McGrew and Berman (1955) in the north, and Bradley (1926) in the northeast. Sears and Bradley (1924), Anderman (1955), Deardorff (1959), Millice (1959), and Culbertson (1961) studied the relationships in the southeastern part of the basin.
