“…Compared with the Lower Member, the distribution area of delta front and shallow lake subfacies next to the Jimusaer region in the Upper Member is relatively large, while that of deep lake subfacies in the study area is relatively small. Generally, oil shale was mainly formed in deep lake subfacies [3,4]. The distribution area of the sedimentary facies fit for the formation of oil shale in the Lower Member is larger than that in the Upper Member.…”

“…Sedimentary environmental parameters, such as paleoclimate, redox conditions and organic matter input, can control the formation of oil shale [12,13]. Geochemical indices are used to characterize ancient sedimentary environments [3,4,14]. Different geochemical indicators were used in this study to reconstruct the sedimentary environments of the Lower and the Upper Member of the Lucaogou Formation in the study area.…”

“…Earlier studies suggest that lake facies are the main sedimentary facies of the Lucaogou Formation. Previously the formation model of the Lucaogou Formation oil shale has been reconstructed [3][4][5]. The formation's oil shale measures can be divided into two: the Lower Member and the Upper Member [5].…”

In this study, the sedimentary and geochemical characteristics of oil shale in the Lower and the Upper Member of the Permian Lucaogou Formation in the southeastern Junggar Basin, Northwest China, were investigated. Mineral and bulk chemical compositions, sedimentary facies and distribution of oil shale show that in the Lower Member it is rich in organic matter, but in the Upper Member, organic-poor. The distribution area of deep lake subfacies and oil shale in the Lower Member is larger than that in the Upper Member. The sedimentary modes of these two members were estimated using geochemical parameters, such as Sr/Cu, the chemical index of alteration (CIA), Ni/Co, V/Sc and (C 27 + C 28)/C 29 regular steranes. The organic-rich oil shale in the Lower Member of the Lucaogou Formation formed in the more humid climate and under oxidative conditions, its organic matter derived mainly from algae. On the other hand, the organic-poor oil shale in the formation's Upper Member formed in the humid climate and under more oxidative conditions, while the input of land plants to its organic matter was high and that of algae low.

“…Depositional environments and petroleum geology of the Turpan-Hami Basin, NW China Recent studies have identified Permian strata within the Turpan-Hami Basin as exploration targets (Zhang et al, 2014). However, the depositional environment during the Permian in the basin is unclear, which has hindered petroleum exploration (Xu et al, 2013).…”
