In the Cambrian or even the early Paleozoic, whether the nearly WE-striking Anyue trough or the NEE-trending Leshan-Longnüsi paleo-uplift implied that the Sichuan Basin suffered from a maximum nearly NS compressional stress and a nearly WE extensional stress which forced the superimposition of t...
Soil sampling According to the geology of Sichuan Province25, the purple rock strata of the Triassic to Cretaceous system mainly consist of the Cretaceous Jiaguan Formation (K2j) and Chengqiangyan Group (K1c) and the Jurassic Penglaizhen Formation (J3p), Suining Formation (J3s), Shaximiao For...
Influenced by Caledonian and Hercynian movements, some shale layers were denuded in local areas including the basin margin and Leshan-Longnüsi palaeohigh. Moreover, the uplifting in Sichuan Basin-northern Guizhou during Devonian and Carboniferous led to the absence of deposits of this period in a...

Intrabasinal southwestern Leshan is the development area of flat-tide marginal beach; with the development area of intraplatform shoal along the Mabian – Kaijiang in the southwest to northeast, Gongxian – Nanchuan in the southeastern basin, eastern Shizhu, eastern Zhongxian, northern Jianshi, ...
Mabian Yi Autonomous County is located in the southeast of Leshan City, Sichuan Province, in the mountainous area of southeastern Sichuan on the southern edge of the Sichuan Basin, as shown in Figure 2. As of now, Mabian Yi Autonomous County governs 12 towns and 3 townships. It borders ...
During the study period, the continuous uplift of Leshan–Longnvsi and Qianzhong–Xuefeng contributed to the effective supply of terrigenous materials. The enrichment of OM weakened under the conditions of a large supply of terrigenous clastic materials. Therefore, the injection of terrigenous debris ...
