摘要
矿体赋存于中元古界昆阳群落雪组第二段(Pt2l2)砂泥质白云岩、细晶白云岩及鹅头厂组(Pt2e)底部的炭质板岩中,矿床受地层、岩性、构造、蚀变多因素控制,其中地层、岩性的控矿尤为明显,属沉积改造型矿床。
The ore body is in Middle Proterozoic Kunyang Group Luoxue Formation Member 2 （Pt2l^2） sandy-muddy dolomitite, fine crystalline dolomitite and Etouchang Formation （Pt2e） bottom carbonaceous slate. The ore deposit is controlled by many factors, such as bed, lithological character, structure and alteration, etc, especially the bed and lithological character, belonging to the ore deposit of sedimentation-reformation type.
