摘要
云南寻甸县金源磷矿,矿体呈层状产于下寒武统渔户村组第二段,矿体层位稳定,矿层产状与地层产状一致,矿层顶、底板为渔户村组白云岩。矿石以Ⅲ级品为主,厚6.30m～21.80m。该磷矿属海相沉积磷块岩、生物碎屑化学沉积型矿床。在矿区东部沿倾斜方向,深部还有进一步找矿的空间。
The orebody of Jinyuan P deposit in Xundian,Yunnan is bedded in Lower Cambrian Yuhucun Formation Member 2.The horizon of orebody is stable,the ore bed and strata are consistent each other in occurrence.The top and bottom of ore bed are Yuhucun Formation dolomitite.The ore is mainly in grade Ⅲ,thickness 6.30m-21.80m.It belongs to the marine sedimentary phosphorite,bioclastic chemical sedimentary deposit.In the E of orefield,the prospecting further will be in the deep along the dipping direction.
