A CONTRAST RESEARCH BETWEEN THE BAIDENG SHALLOW-SEA FACIES AND QINGLONGSHAO CONTINENTAL FACIES PHOSPHORITE IN YUNNAN PROVINCEE

The Baideng phosphorite deposit is of shallow-sea facies; while the Qinglongshao phosphorite belongs to continental facies. Both of them are important phosphate ore mining bases in Anning, Yunnan Province, with high grade and big reserves. The goyazite ore bed and kaolin claystone unconformably overlap the Qinglongshao breccia phosphate, which is characterized by continental facies phosphorite, without the shallow-sea characters of primary sedimentary structure. The Baideng deposit contains two layers of commercial ore; while the Qilongshao deposit includes only one layer.
