Relatively high-resolution clay mineralogical and chemical index of alteration (CIA) analyses were conducted on the terrestrial Lubei section in southwestern China, to gain a better understanding of the paleoclimatic/paleoenvironmental evolution on land during the Permian-Triassic transition (P-Tr transition). Clay-mineral species include illite-sm...

There are Upper Devonian (Frasnian to Famennian) limestone outcrops in the Maoying area, north of Ziyun County, South China and they represent carbonate platform deposition with some patch reefs, as part of a shallow-water carbonate sedimentary formation in the Late Devonian nearshore environment. The Late Devonian carbonate deposition is, to the e...

Facies and carbon isotope analysis of a series of four drill cores from Cincinnati, Ohio provide an opportunity to assess Late Ordovician paleoenvironmental variability along the margin of the Sebree Trough, an intracratonic basin associated with Taconian far-field tectonics. The cores provide stratigraphic data for an approximately 50km long NE-SW...

In order to understand redox variations and organic matter accumulation on the Yangtze carbonate platform during the late Ediacaran-early Cambrian, petrological and geochemical studies of several wells were carried out in this work. Our data suggest that depositional environments were dominated by oxidizing bottom water conditions during the late E...

The “Utica Formation” and “Point Pleasant" (mixed shale and thin limestones) of driller’s terminology is a major target for unconventional oil and gas development in eastern Ohio, and is the largest producing unit in the state of Ohio. Despite major production yields from this unit, the paleoenvironmental interpretations, stratigraphic nomenclature...

Diploporites, like most pelmatozoan echinoderms, are characterized by complex multi-element skeletons prone to complete disarticulation if left exposed for extended periods of time. Consequently, preservation of abundant articulated diploporite thecae is rare and generally restricted to environments where rapid burial events could catastrophically...

The Upper Ordovician (Katian: Mohawkian; ~451-453 million year-old) Lexington Formation of northern Kentucky was deposited in a shallow platform sea in the southern subtropics (~25ºS). A general lack of corals and sponges and enrichment in granular phosphates has suggested that these carbonates accumulated under cool conditions and upwelling of nut...
