Ore types are limonite fractured silicic sandstone, quartz veinlet and bedded flysch rhythm ore.

矿石类型为褐铁矿化破碎硅化砂岩、石英细脉和层状复理石韵律矿石。

There was a typical "two-layer structure" in Dapingzhang Cu-polymetal deposit, which was composed of the upper massive sulfide orebody and lower veinlet-disseminated sulfide orebody.

前言： 大平掌矿床由上部层状块状硫化物矿体和下部细脉浸染状矿体组成， 双层结构清楚。

The mineralization stages include: quartz, pyrite-quartz, pyrite veinlet, multi-metal sulfide and calcite-quartz. The multi-metal sulfide stage is the main mineralization stage among them.

成矿阶段包括石英脉、黄铁矿石英、黄铁矿细脉、多金属硫化物、方解石石英阶段，多金属硫化物阶段为主要成矿阶段。
