Shale oil stored in the shale system occurs mainly adsorbed and free states, ascertaining amount of crude is a method its content, which determines accuracy resource evaluation. Both inorganic minerals kerogen have ability to adsorb oil, but there controversy surrounding plays greatest part doing so; clarifying this would be great significance Therefore, study, evolution states were changed usi...

the nayband formation was measured and sampled in parvadeh area, southern tabas city. in this area, this formation has a thickness of 1410 m, dividing into four members, namely gelkan, bidestan, howz-e-sheikh and howz-e-khan. a total 573 samples were treated for palynological analysis, and only 120 samples were productive. a total of 57 miospore taxa and 11 plant macrofossil were encountered. b...

Lower Paleozoic source rock (SR) characteristics and paleo-depositional environments are not well understood in the Barents Sea region. Organic inorganic geochemical analyses of 17 carbonaceous samples from Cambrian Tokammane Formation, to Middle Ordovician Kirtonryggen Valhallfonna formations Ny Friesland, north-east Spitsbergen, show that there is a striking difference petroleum generation po...

The Lower Paleozoic marine shale in southern China has undergone several strong tectonic transformations an extensive region outside the Sichuan Basin. Although some strata underwent deformation, they still contain a significant amount of gas. gas preservation mechanism strongly deformed become focus attention. In this paper, Cambrian gas-bearing samples with deformation taken from exploration ...

The Permian-Triassic Mass Extinction (PTME) is the greatest biodiversity crisis in Earth history and while marine increasingly well constrained, timing cause(s) of terrestrial losses remain poorly understood. There have been suggestions that End-Permian Terrestrial Collapse (EPTC) pre-dated, was synchronous with or post-dated crisis, even occurred asynchronously different regions. We address th...
