Abstract
On the basis of salinity and organic geochemical analyses of mudstones, this paper analyzed the relationship between salinity and sedimentary facies of different strata; studied influences of salinity on organic matter richness, types, and thermal maturities of source rocks; and built the organic enrichment accumulation model for the Paleogene and Neogene saline lakes of the western Qaidam Basin. In the western Qaidam Basin, saline lake depocenters and high salinity areas migrated eastward, and chloride ion (Cl–) concentration of source rocks showed an increasing trend from the Paleocene to Pliocene. The relationship between organic matter content and salinity of the Paleocene and Pliocene source rocks shows a three-interval model: both TOC (total organic carbon) content and chloroform bitumen content have low values at the low salinity stage, first increase to the peak and then decrease to the lowest values at the medium salinity stage, and sustain the lowest values at the super saline stage because of t...
