| Abstract: | The Shengzhou diatomite deposit, located in the Shengzhou-Xinchang basin, is recognized as one of the largest diatomite deposits in China. The scanning electron microscopy (SEM-EDS), mineral compositions and elemental geochemistry of the samples were analysed to identify the nutrient sources, depositional environments, and mineralization process. Through scanning electron microscopy, the predominant diatom species observed are Aulacoseira granulata (Ehrenberg) Simonsen and Cyclotella shengxianensis Huang and Cai. The results of X-ray diffraction (XRD) analysis results indicate that the mineral composition of diatomite mainly consists of opal-A, quartz, clay minerals, feldspar, carbonate minerals, and pyrite. The results of XRF and ICP-MS analysis show that the content of SiO2 ranges from 59.11% to 69.44%, and the trace nutrient elements such as Mo, U, V, Co, Ni, Cu, and Zn are enriched. The correlation of geochemical composition between diatomite and Cretaceous volcanic rocks in the study area indicates that the weathering of volcanic rocks provides nutrients for diatom growth. Multiple geochemical indicators (Sr/Ba, V/Cr, Ni/Co, U/Th, V/(V+Ni), C-value, CIA, and Sr/Cu) and palaeontological evidence indicate that the diatomite was formed in a freshwater, oxic, and hot-humid environment. As the diatomite is susceptible to denudation, the overlying basalt may protect the deposit. [ABSTRACT FROM AUTHOR] |
