摘要
Abstract
The Dongyi mining area of Kaiyang phosphate mine in Guizhou province is a newly discovered super-large phosphate-rich deposit, and Yangshui formation is the main occurrence horizon of phosphate deposits. Based on the characteristics of phosphate ores in the study area, the ore types were divided, and the results showed that: Sand-gravel phosphate rock is the most common type of phosphate rock, followed by stromatolite phosphate rock, and other types are relatively rare. Different types of phosphorites correspond to different special sedimentary environments. On the whole, the study area is located in the intertidal zone-subtidal high-energy zone, which leads to the formation of high-grade phosphorus blocks after multiple stages of depositional, crushing, wave separation, flushing and redeposition of the micritic phosphorus blocks.关键词
