Large-Scale Formation of Manganese, Phosphorus, and Aluminum Deposits in Guizhou, China and Global Deep-Time Changes

Guizhou Province in South China contains relatively completed Neoproterozoic—Late Paleozoic strata, providing valuable records for some important geological events, such as the “Snowball Earth” Event, the Ediacaran biota, the far-field effect of Late Paleozoic Ice Age (LPIA) and the Emeishan Large Ingenious Province (ELIP). Interestingly, these geological events not only had critical effects in the evolution of surface environment of Earth, but also had oblivious metallogenic effects. A series of sedimentary deposits are found in the contemporaneous strata of these geological events, The “Datangpo-type” manganese deposit within the interglacial strata of Cryogenian, the phosphorite deposit coexists with the Ediacaran biota (Weng’an Biota), the Carboniferous bauxite deposit indicating the regression of the LPIA, the Permian manganese deposit linked with the ELIP. In this fieldtrip, we will travel through the most representative sections of all these sedimentary deposits, including the orebodies and depositional deformations in the basal Datangpo Formation in Songtao, the cap carbonate, phosphorite deposit and the Weng’an Biota in the Doushantuo Formation in Weng’an, and the Carboniferous bauxite deposit and the Permian manganese deposit in Zunyi.
