%X 本文对辽宁省32个典型的金、铅锌及铜矿床的自然重砂矿物进行统计分析。总结发现，不同矿种对应不同的重砂矿物组合：如自然金、黄铁矿、黄铜矿、方铅矿、辰砂、白钨矿等对金矿床具有较好指示意义；铅族矿物、铜族矿物、黄铁矿、磁铁矿、辉钼矿等对铅锌矿床具有较好指示意义；而铜族矿物、黄铁矿、磁铁矿、方铅矿、辉钼矿等对铜矿床具有较好指示意义。相同矿种中不同成因的矿床其对应的重砂矿物组合也存在一定差异：例如VMS型铜矿床的重砂指示矿物组合为：铜族矿物 + 黄铁矿 + 磁黄铁矿 + 磁铁矿 + 镜铁矿；矽卡岩型铜矿床的为：铜族矿物 + 黄铁矿 + 磁铁矿 + 方铅矿 + 辉钼矿。这些规律对于今后在辽宁地区建立不同成因类型的金、铅锌及铜矿的自然重砂找矿模型具有重要指示意义。<br />
Assemblages of natural heavy mineral from 32 typical gold, lead-zinc and copper deposits in Liaoning province were analyzed. We found that different kinds of ore deposits have different kinds of natural heavy minerals. Variable mineral assemblages of native gold, pyrite, chalcopyrite, galena, cinnabar and scheelite can be used as indicators for gold ore prospecting. The leady minerals, the branze minerals, pyrite, magnetite and molybdenite can be used as indicators for lead-zinc ore prospecting. And the branze minerals, pyrite, magnetite, galena and molybdenite can be used as indicators for copper ore prospecting. Typomorphic mineral assemblages are variable in different genetic style of deposits. For example, the typical heavy mineral assemblages in VMS copper deposit is of the branze minerals + pyrite + pyrrhotite + magnetite + specularite, whereas the branze minerals + pyrite + magnetite + galena + molybdenite are of typical heavy mineral assemblages in Skarn copper deposits. These laws are useful for further different kinds of gold, lead-zinc and copper deposits prospecting in Liaoning province.
