摘要
Abstract
The Bagu Phosphate Mine is located in the southwestern part of Leibo County,Sichuan Province,and is a shallow marine layered carbonate phosphate rock deposit.The phosphate ore is hosted in the middle section of the Maidiping Formation.The ore bodies include No.I and No.II,with the grade of No.II ore body(average grade of 24.62%)being higher than that of No.I ore body(average grade of 21.33%).The ore types are mainly dense massive phosphate rock,striped and banded phosphate rock,and porous phosphate rock.The structures are mainly sandy clastic,followed by gravelly sandy clastic,oolitic,and micritic structures.The ore minerals are mainly colloidal apatite and minor crystalline apatite.Based on a comprehensive analysis of previous research results,it is concluded that the source of the mineralizing material of the Bagu Phosphate Mine is mainly seawater and is closely related to biological activity.The synsedimentary basin formed at the depression site is a favorable structure for mineralization.The sedimentary environment directly affects the physical enrichment of phosphate ore.The high-energy subtidal facies during the regression-transgression transition period is a favorable facies belt for phosphate deposition and is a key area for future exploration and development.关键词
