... and Meadow Creek oil fields. Partridge (1957 , p. 884) considered the Parkman sandstone as the upper member of the Mesaverde and included the Sussex and Shannon sandstones, generally considered sandstone beds in the Steele shale, in the basal part of his Mesaverde formation. In the southeastern part...

... highly fertile basaltic soils between volcanic eruptions that were closely spaced in time or space. A corollary, that relative abundance criteria will be of limited biostratigraphic value in this region, is supported by marked differences in the composition of the Black Duck Creek diatomite microflora...

In the Black Hills, the Fox Hills sandstone overlies and is transitional with Pierre shale; the Fox Hills is overlain by the non-marine Hell Creek formation. Correlations and facies changes across...

...%. These figures represent an important increase over 1952, when 527 development wells resulted in 382 oil wells and 10 gas wells, making a success ratio of 74%. The most active spot was the Clareton-Cheyenne River-Black Thunder Creek trend where a minor boom was under way by the end of the year. Grass Creek...

... Christo Formations ( Dirks and Berger, 2013 ). At Sterkfontein Cave the fossils are generally encased in calcified breccia containing clasts of dolomite, chert, mixed with surface-derived soil particles embedded in a sandy matrix ( Wilkinson, 1973 , 1983, 1985 ; Partridge, 1978 , 2000...

Other undated granitoid units in the Salmon River canyon include the Spring Creek gneiss, Partridge Creek gneiss, and the Keating Ridge gneiss, which form narrow (∼1 km wide) belts oriented subparallel to the arc–craton boundary ( Fig. 3 a ).

... ( Emmett and others, 2000 ). Much of the research on macroinvertebrates has been done in order to assess the impacts of anthropogenic influences on the Salish Sea, particularly Puget Sound ( Long and others, 2006 , 2008 ; Partridge and others, 2010 ). Until now, however, this has been the only...

...JOHN F. PARTRIDGE, JR ABSTRACT The Powder River basin of Wyoming offers potentialities for oil and gas accumulations in stratigraphic traps in Upper Cretaceous sands. These potentialities are discussed on a broad basis, at an early stage in development; detailed studies may be undertaken...

... in rhyolites. Rhyolites of the Partridge Lake and Jones Creek formations contain sanadine, while dacites of the Cleft Mountain formation contain sparse quartz. Mafic minerals are rarely observed as phenocrysts in the BLVC, with amphibole being the most common phase, but with sparse anhedral augite occurring...

All but one of the major pools discovered to date—Big Sand Draw (No. 25), Beaver Creek (No. 20), Winkleman Dome (No. 10), Pilot Butte (No. 9), Steamboat Butte (No. 8), and Circle Ridge (No. 4)—are in the western part of the basin; the exception is Grieve...

Data recorded by the Wyoming Geological Association (1957b) and Biggs and Espach (1960 , p. 62), however, show that these two fields are unique in the Wind River basin in possessing vertical...
