摘要
何家坪铅锌矿产于震旦系上统灯影组上部白云岩中,明显受层位限定,矿体穿层现象明显,受节理、裂隙等小构造控制,矿石自然类型有含黄铁矿方铅矿闪锌矿型、含闪锌矿方铅矿(黄铁矿)型、闪锌矿型、方铅矿型,围岩蚀变主要有重晶石化、白云石化、黄铁矿化、硅化及碳酸盐化,矿床成因类型为碳酸盐岩中原地矿质渗流水淀积矿床。
Hejiaping lead-zinc deposit is hosted in the Sinian system of Denying Formation in the upper dolomite,obviously limited by the horizon.The phenomenon of significant ore body wear layer is controlled by joints,cracks and other small structure.Natural types of ore contain pyrite galena sphalerite-type,sphalerite crystallites galena(pyrite) type,sphalerite type and galena type.Type of wall-rock alteration are mainly barite,dolomitization,pyritization,silicification and carbonation.Type of ore genesis is carbonate deposition of the central plains to the mineral deposits in water seepage.
