Oil shales are developed in the Shale Member of Middle Jurassic Shimengou Formation Qaidam Basin, China. The oil can be classified into three quality groups (low-, medium-, and high-quality shales) through a comprehensive analysis protocol that includes Rock-Eval pyrolysis, total organic carbon (TOC) content, proximate analysis, gas chromatography-mass spectrometry (GC-MS), X-ray diffraction (X...

Organic matter in sediments is dominated by kerogen, a high molecular weight geomacromolecule. Kerogen can be subdivided into Types I to IV that provide paleoenvironmental and petroleum potential information. typing performed several chemical methods including elemental analysis (H/C O/C), FTIR pyrolysis-gas chromatography techniques. However, kerogens occur naturally within mineral matrices th...

The stratifi ed red beds of the Catskill Formation are conspicuous in road cut exposures on the Allegheny Plateau of north-central Pennsylvania. During this fi eld trip we will visit and explore several fossil localities within the Catskill Formation. These sites have been central to recent investigations into the nature of Late Devonian continental ecosystems. By the Late Devonian, forests wer...

The eastern escarpment breaks of the Southern High Plains Texas are both a geomorphic and ecotonal transition zone from high plains surface to Rolling below. geoarchaeological record on is well documented, but few studies have investigated sediments, soils, geochronology escarpment. current investigation has targeted discontinuous remnants Late Quaternary deposits within Spring Creek, tributary...

The purpose of this research was to examine paleoenvironments, hydrothermal activity, and seawater restriction the lower Cambrian Niutitang Formation shale gas reservoir in eastern Xuefeng uplift determine factors affecting organic matter (OM) enrichment. In studied borehole Xiangan 1 well western Hunan Province, can be subdivided into Niu1, Niu2, Niu3 Members based on geological geochemical fe...

Marine Isotope Stage (MIS) 5 and 4 are periods of major cultural innovations in the Middle Stone Age (MSA) southern Africa. While extensive data is available for coast, far less known about interior, particular its central plateau. This likely due to large geographic extent this area a general paucity caves rock shelters that can provide long stratigraphic sequences environmental records. The l...

detailed log facies studies of miocene succession in the well rashidpur-04, rashidpur structure, surma basin were carried out by integrating wireline log and limited core sample data in order to reconstruct the paleoenvironments of deposition. based on the analysis of the log motifs, grain size, sand/shale ratio and major change in gamma ray log motifs, two major depositional sequences were ide...
