| 摘 要： | 云南省镇雄县银厂湾磷矿为隐伏矿,矿体呈层状赋存于下寒武统梅树村组( 1ms),现已控制三个矿体,矿体产状与岩层产状一致,均较为平缓。矿体矿石矿物为胶磷矿、微晶碳磷灰石和氟磷灰石。通过研究,该矿床形成于海湾潮下低能带的古地理环境,主要由富磷生物碎屑沉积聚集而成,属沉积的碳酸盐-硅质层状磷块岩矿床。

| Abstract: | Yinchangwan P deposit is a buried deposit,the orebody is bedded in Lower Cambrian Metshucun Formation(∈1ms).There are 3 orebodies controlled,which are consistent with rock bed in occurrence,rather gentle.The oremineral are cellophane,microcrystalline podolite and fluor apatite.Acording to the study,the ore deposit is formed in the paleogeographic environment of gulf subtidal low energy zone,formed mainly by the aggregation of P-rich bioclastic sediment,belonging to the sedimentary carbonate-siliceous bedded phosphorite deposit. |
