根据铜矿床的成因类型，对全国177个铜矿床的自然重砂矿物进行统计分析。结果显示，自然重砂矿物对于铜矿床成因类型具有较好的指示意义。不同成因类型铜矿床的自然重砂矿物组合不同，尤其是岩浆型、斑岩型、矽卡岩型、火山岩型铜矿床均具有特征自然重砂指示矿物。除了铜矿物、铅锌矿物、黄铁矿、白钨矿等各类型铜矿床共有自然重砂矿物外，铬铁矿、镍黄铁矿、辉石、橄榄石等为岩浆型铜矿床的特征指示矿物，自然金、辉钼矿、磷灰石、磷钇矿等可以指示斑岩型铜矿床；锆石、锡石和石榴子石是矽卡岩型铜矿床的特征指示矿物；火山岩型铜矿床则以雄黄、雌黄作为特征指示矿物。这些研究对于建立不同成因类型铜矿的自然重砂找矿模型具有重要意义。

Statistics of natural heavy minerals form 177 copper deposits distributed widespread in China show that the natural heavy mineral assemblages of various genetic types of copper deposits are varied and distinctive. Natural heavy mineral assemblages can be used as indicators to denote magmatic type, porphyry type, skarn type, and volcanic type copper deposits. Besides such minerals as copper minerals, lead and zinc minerals, pyrite and scheelite which are commonly existent in copper deposits, chromitites, pentland?ite, pyroxene and olivine can also be regarded as indicator minerals for magmatic type copper deposits, and native gold, molybde?nite, apatite and xenotime are typical indicator minerals for porphyry type copper deposits. The indicator minerals for skarn type copper deposits are of the zircon, cassiterite and garnet assemblage, and realgar and orpiment are characteristic of volcanic type cop?per deposits. The results achieved by the authors are useful to building natural placer prospecting models for different genetic types of copper deposits.
