The U.S. Geological Survey (USGS) recently completed an assessment of the technically recoverable undiscovered hydrocarbon resources Appalachian Basin Province. province includes parts New York, Pennsylvania, Ohio, Maryland, West Virginia, Kentucky, Tennessee, Georgia and Alabama. was based on six major petroleum systems, which include strata that range in age from Cambrian to Pennsylvanian. Devonian Shale-Middle Upper Paleozoic Total Petroleum System (TPS) extends generally York Tennessee....

Four millennial-scale latest Pleistocene to Holocene climatic cycles are recorded by aeolian-lacus trine strata along the southern margin of Chott Rharsa, a playa situated within an active tectonic basin northern Sahara Desert in Tunisia. Cycles characterized (1) humid phase dunefield stabilization and high lake levels, (2) arid desiccation deflation with construction. The overall define progressive drying trend correlate well detailed chronology from Morocco region general for early...

Much of the oil and gas in Illinois, Michigan, Appalachian basins eastern North America is thought to be derived from Devonian shale that within these (for example, Milici others, 2003; Swezey, 2002, 2008, 2009; Swezey 2005, 2007). As strata were buried by younger sediments, was subjected great temperature pressure, some areas crossed a thermal maturity threshold began generate oil. With increasing burial (increasing pressure), this oil-generating another natural gas. Knowledge therefore...

Abstract The Carolina Sandhills is a physiographic region of the Atlantic Coastal Plain province in southeastern United States. In Chesterfield County (South Carolina), surficial sand this Pinehurst Formation, which interpreted as eolian derived from underlying Cretaceous Middendorf Formation. This has yielded three clusters optically stimulated luminescence ages: (1) 75 to 37 thousand years ago (ka), coincident with growth Laurentide Ice Sheet; (2) 28 18 ka, last glacial maximum (LGM); and...

Using a geology-based assessment methodology, the U.S. Geological Survey estimated mean of 70.2 trillion cubic feet undiscovered natural gas, 54 million barrels oil, and 872 gas liquids in Appalachian Basin Province.

Geologic cross section D-D' is the second in a series of sections constructed by U.S. Geological Survey to document and improve understanding geologic framework petroleum systems Appalachian basin. Cross provides regional view structural stratigraphic basin from Findlay arch northwestern Ohio Valley Ridge province eastern West Virginia, distance approximately 290 miles. The information shown on based geological geophysical data 13 deep drill holes, several which penetrate Paleozoic...

Although more than 100 years of research have gone into deciphering the stratigraphy Michigan basin North America, it remains a challenge to visualize on regional scale and describe stratigraphic relations within basin. Similar difficulties exist for visualizing describing distribution petroleum source rocks reservoir rocks. This publication addresses these by combining data Paleozoic Mesozoic geology The areal extent this structural is presented along with in eight schematic...

Sand hills in the Savannah River valley Jasper County (South Carolina, USA) are interpreted as remnants of parabolic eolian dunes composed sand derived from and stabilized by vegetation under prevailing climate conditions. Optically stimulated luminescence ages reveal that most were active ca. 40 to 19 ka ago, coincident with last glacial maximum (LGM) through early deglaciation. Modern surface winds not sufficient for sustained transport. When active, blew at velocities least 4 m/s west...

Geologic cross section E-E' is the first in a series of sections planned by U.S. Geological Survey (USGS) to document and improve understanding geologic framework petroleum systems Appalachian basin. Cross provides regional view structural stratigraphic basin from Findlay arch northwestern Ohio Valley Ridge province eastern West Virginia, distance approximately 380 miles (mi) (fig. 1, on sheet 1). updates earlier through central Renfro Feray (1970), Bennison (1978), Bally Snelson (1980)...

Using a geology-based assessment methodology, the U.S. Geological Survey estimated following quantities of undiscovered, technically recoverable oil and gas resources in Illinois Basin, USA: (1) mean 214 million barrels oil; (2) 4.65 trillion cubic feet natural gas; (3) 24 liquids.

Geologic cross section C-C' is the third in a series of sections constructed by U.S. Geological Survey (USGS) to document and improve understanding geologic framework petroleum systems Appalachian basin. Cross provides regional view structural stratigraphic basin from north-central Ohio Valley Ridge province south-central Pennsylvania, distance approximately 260 miles (mi). This companion E-E' D-D' that are located about 50 125 mi 25 mi, respectively, southwest. contains much information...

This report presents the results of a U.S. Geological Survey (USGS) assessment technically recoverable undiscovered natural gas resources in Devonian shale Appalachian Basin Petroleum Province eastern United States. These are part USGS 2002 oil and province. does not use 2011 Marcellus Shale because area considered is much greater than described this report. The was based on identification six total petroleum systems, which include strata that range age from Cambrian to Pennsylvanian. shales...

The publication combines data on Paleozoic and Mesozoic stratigraphy petroleum geology of the Illinois basin, U.S.A., in order to facilitate visualizing a regional scale stratigraphic relations within basin. Data are presented eight schematic chronostratigraphic sections arranged approximately from north south, with time denoted equal increments along sections, addition areal extent this structural modified Hass (1956), Conant Swanson (1961), Wilman others (1975), American Association...

This paper presents a brief review of criteria used for identifying eolian sands and sandstones. Many features sand grains are not unique to environments, therefore one must be very careful in making environmental interpretations based only upon grain characteristics. The identification stratification types provides another potential means In particular, ripple laminae different subaqueous systems, the proper wind-ripple is an excellent method Cette note présente brièvement les critères...
