Pyrite is one of the important components of shale and plays a crucial role in shale gas enrichment.However,currently there are just a few studies on this subject matter.Therefore,the characteristics of pyrite in orga...
Organochlorine pesticides (OCPs) found in rivers from the Sichuan Basin to Aba Prefectttre profile were analyzed to assess possible health risks to adults and children who use the river as a source of drinking water...
The Lower Triassic Feixianguan Formation at the well-known Puguang gasfield in the northeastern Sichuan Basin of southwest China produces a representa- tive oolitic reservoir, which has been the biggest marinesourced ...
