Geochemistry of Mariano Lake-Lake Valley Cores, McKinley County, New Mexico

Geochemistry of Mariano Lake-Lake Valley Cores, McKinley County, New Mexico

Date: 1990
Creator: Leventhal, Joel S.
Description: From abstract: The primary goal of the U.S. Geological Survey-Bureau of Indian Affairs drilling project in the Upper Jurassic Morrison Formation in McKinley County, New Mexico, was to better understand the relationship between host-rock stratigraphy and uranium mineralization. As part of this project, geochemical studies of approximately 280 samples from 8 cores and 1 outcrop were undertaken; samples from 4 of the cores show uranium enrichment. Geochemical relationships between samples of weathered outcrop, oxidized core, reduced (unmineralized) core, and ore-bearing core were contrasted by comparison of element abundances.

Geologic History and Hydrocarbon Potential of Late Cretaceous-Age, Low-Permeability Reservoirs, Piceance Basin, Western Colorado

Geologic History and Hydrocarbon Potential of Late Cretaceous-Age, Low-Permeability Reservoirs, Piceance Basin, Western Colorado

Date: 1989
Creator: Johnson, Ronald Carl
Description: From abstract: The Piceance basin of western Colorado contains large reserves of natural gas in low-permeability reservoirs of the Late Cretaceous-age Mesaverde Formation or Mesaverde Group. The gas accumulation can be divided into three general zones: a zone of surface-water invasion that extends inward a few miles from present outcrops, a gas-and-waterbearing zone that extends 10-20 miles inward from the water-bearing zone, and a central, predominantly gasbearing zone.

Fluvial Architecture of the Lower Cretaceous Lakota Formation, Southwestern Flank of the Black Hills Uplift, South Dakota

Fluvial Architecture of the Lower Cretaceous Lakota Formation, Southwestern Flank of the Black Hills Uplift, South Dakota

Date: 1995
Creator: Dahlstrom, David J. & Fox, J. E.
Description: From introduction This report describes large-scale depositional units referred to as architectural elements, interpreted from outcrops of three distinct fluvial sandstone units of the Lakota Formation in the southwestern Black Hills area of Custer and Fall River Counties, South Dakota. These fluvial deposits formed near the end of an episode of continental deposition that began when the Jurassic Sundance sea regressed from the region and ended when the Early Cretaceous Skull Creek sea encroached from the north in Albian time.

Date: 1992
Creator: Karachewski, John A.
Description: From abstract: Siliciclastic and minor carbonate rocks of the lower part of the Middle Pennsylvanian Minturn Formation of north-central Colorado were deposited in alluvial-fan, braidplain, Gilbert-delta, shoreline, and paralic, and offshore-marine environments. These strata can be divided into twelve genetic sequences that are generally bounded by transgressive surfaces of erosion or paralic flooding surfaces, and are characterized by thin and thick transgressive units. This report examines the paleogeography of this area.

[Evolution of Sedimentary Basins--Uinta and Piceance Basins: Chapters H and I]

Date: 1989
Creator: Nuccio, Vito F.; Johnson, Ronald Carl & Johnson, Samuel Y.
Description: From abstract: Analysis of vitrinite reflectance profiles and surfaces of equal vitrinite reflectance in the southeastern part of the Piceance basin, northwestern Colorado, indicates that burial histories for the Divide Creek anticline and the Grand Hogback are different from those for adjacent synclines. These two positive structures probably reached their present-day thermal maturity before late Eocene folding and before the end of the Laramide orogeny. In contrast, adjacent synclines did not reach their present-day thermal maturity until the end of the Laramide orogeny, or possibly later.
