Achievement summary

Ÿ   Genetic study of Carboniferous and Permian bauxite deposits in Guizhou and Guangxi provinces. Based on traditional and new methods such as thin sections, SEM, XRD, XRF, ICP-MS, biomarker and LA-ICP-MS, I analyzed the metallogenic environment and ore-forming conditions of these bauxite deposits, and constructed metallogenic models. The key metallogenic factors were appropriate climatic and tectonic background, paleogeographic controls on the distribution and thickness of the bauxite deposit, and a leaching process that influenced ore quality.

Ÿ   Geochronological study of Ordovician-Silurian clastic strata in Guizhou-Hunan-Chongqing area, South China. My results indicated that the Cathaysia Block, which was located on the northern margin of the Gondwana supercontinent, provided clastics to the Yangtze Craton during the Guangxi Movement. Meanwhile, the Jiangnan Tectonic Belt was reactived during the Silurian Period and also provided clastics to the Yangtze Craton.

Ÿ   Sr and Nd isotopic and geochemical studies of Cryogenian manganese deposits of the Datangpo Formation (~660 Ma) in northeastern Guizhou. My results verified a hydrothermal source for the manganese. Combined with sedimentary and petrographic evidences, I proposed the episodic post-glacial ventilation model for the Datangpo manganese deposit.

Ÿ   I reported the first discovery of cap carbonate deposits in South China following the Sturtian glaciation (720-660 Ma). My analysis indicates that this cap carbonate at the bottom of the Datangpo Formation and the manganese deposit were contemporaneous heterotopic facies, and that their distribution was controlled by water depth and water-column stratification in the Nanhua Basin in the post-glacial period.


Research prospects

Ÿ   The bauxite deposits of central Guizhou formed in the Early Carboniferous, representing terrestrial weathering products prior to the Late Paleozoic Ice Age. I believe that this bauxite deposit records regional paleoclimatic changes, and that it is necessary to place this deposit in a context of global paleoclimatic change in order to clarify its metallogenic mechanism.

Ÿ   Researchers still do not know much about the post-Sturtian glaciation cap carbonate in South China. The newly discovered post-Sturtian cap carbonate is important as a globally correlative stratigraphic marker and for the insights it provides regarding environmental changes following a major Snowball Earth event. In future work, I will use geochemical methods to analyze cap carbonate samples in order to acquire more paleoenvironmental information.

Ÿ   Under the guidance of Prof. Algeo, I am now compiling my own and published global inorganic and organic carbon isotope data through geological time. We will examine whether there is a correlation between the inorganic and organic carbon isotope data, and if a change in slope was linked to bioevolutionary events. This work will help us to better understand the global carbon cycle and its relationship to the evolution of life on Earth.
