To characterize the coal measure shale pore structure of Xiashihezi Formation in Sunan Syncline block, a series experiments were conducted. Results show that main components shales are clay minerals and quartz, organic matter, fluid escaping, interlayer, intercrystalline interparticle pores well-developed. The specific surface area (SSA) is concentrated with size <50 nm significantly hig...

The Quetta and surrounding areas are part of the collision zone between Indian Eurasian plates, named as Kirthar Sulaiman Fold-Thrust belts. is accommodated by folding, thrusting Nushki-Chaman Transform Fault System. Detailed high-resolution (scale 1:50,000) mapping structural analyses were carried out using modern remote-sensing techniques ArcGIS to understand mutual relationships patterns geo...

The lowstand extensions of two fluvial systems from the Cascadia subduction margin are investigated using high-resolution seismic reflection data to determine relative controls on paleodrainage morphology. We document distinct differences between systems, located ~40 km apart, attributed underlying structure and lithology, shelf gradient, drainage basin characteristics. A cross-shelf valley exi...

Mammalian fossils from two principal collecting areas in the lower Hanna Formation of the Carbon Basin comprise three faunas, the Grayson Ridge, Halfway Hill, and Sand Creek faunas. The Grayson Ridge and Halfway Hill faunas are diverse, consisting cumulatively of 29 mammalian species, at least two of which are new. The faunas are approximately equivalent in age and are either latest lbrrejonian...

Inherited and syn-compressional salt-controlled structures in orogens are difficult to distinguish from compressional features because classical salt (halokinetic growth strata, welds) can be misinterpreted as shortening-related (syn-kinematic tectonic unconformities). In the Sivas basin Turkey, syn-kinematic diapirism entirely shaped architecture of foreland allowed development primary seconda...
