摘　　要：对宁夏中宁县土窑铜矿床进行研究,分析了该矿床地质特征和围岩蚀变,认为褐铁矿化、黄铁矿化、硅化蚀变与矿化关系密切,并将矿石划分为氧化铜矿石、硫化铜矿石及混合铜矿石3种;通过对包裹体温度和盐度的测试分析,并结合硫化矿石中矿物的共生组合特征等研究,提出土窑铜矿属于低温热液型矿床;归纳该矿床的4种找矿标志,对进一步的勘探具有参考价值.A detailed study has been carried out on the geological characteristics and wallrock alteration of the copper deposit atTuyao in Zhongning Ningxia. Limonitization, pyritization and silicification are hand in glove with mineralization. Ores of the deposit may be classified based on their composition into three types, including cupricoxided, cupric sulfide and mixed ores. Combined test analysis of inclusion temperatrue and salinity and mineral symbiosis in cupric sulfide ore, the viewpoint is brought forward that the Tuyao copper deposit is low temperature hydrothermal deposit.Four prospecting marks are concluded and benefit to further exploration with a reference value.
