Foraminifers Of The Clarita Formation (Wenlock, Silurian), From The Arbuckle Mountains, Oklahoma
(Geology, 2014-12)The study, identification, and classification of Silurian foraminifers from the Arbuckle Mountains in Oklahoma have attracted little attention since the work of Moreman and Ireland in late 1930's. These authors described ... -
The Formation And Obduction Of Ophiolites Since The Late Precambrian
(Geology, 2007-08-23)Ophiolite formation and emplacement has been episodic since the Late Precambrian. This research study examines ophiolites that formed during the Cenozoic, Mesozoic, Paleozoic and Late Precambrian. The ophiolites were ... -
FRACTURE DENSITY AND BRITTLENESS OF THE MESOZOIC FORMATIONS EXPOSED ON THE CANADIAN ESCARPMENT OF EASTERN NEW MEXICO
(2018-07-02)Production of hydrocarbons from tight and unconventional reservoirs has become so prevalent, the need to understand rock fracture mechanics has become increasingly important. A specific research goal is the need to understand ... -
Fracture Density Of Units In The Brushy Canyon Formation, Whitehorse Group And Winchell Formation Of The Permian Basin.
(Geology, 2013-10-22)This study tests the theoretical equation(Fd Ua)/μ=A v/(1-2v)+B, where Fd equals the fracture density present in a geologic unit under constant strain conditions. The material properties in the equation were measured using ... -
Fusulinid and conodont biostratigraphy of the Upper Pennsylvanian–Cisuralian Riepe Spring Limestone, Spruce Mountain Ridge, Elko County, Nevada, U.S.A.
(2018-12-06)The Upper Pennsylvanian-Cisuralian (lower Permian) mixed carbonate-siliciclastic strata exposed at Spruce Mountain Ridge, Elko County, Nevada, record the shallow-marine microfauna and oscillating depositional history of ... -
Geochemical Analysis Of The Woodford Shale, Anadarko Basin, Oklahoma
(Geology, 2014-07-14)The Woodford Shale is a dark, siliceous mudstone that was deposited in a rift basin during late Devonian to early Mississippian times. Three drill cores containing the Woodford Shale from the Anadarko Basin, Oklahoma, have ... -
GEOCHEMICAL AND PETROPHYSICAL CHARACTERISTICS OF THE HORN RIVER FORMATION: BRITISH COLUMBIA, CA
(2017-05-23)The Devonian Horn River basin of northeastern British Columbia is the largest producing shale gas field in Canada. It has an estimated 500-600 TCF of light hydrocarbons in place stacked in multiple formations in an ... -
