摘要
四川冕宁太洋沟铅锌矿床位于康滇地轴北段,笔者通过矿区系统采集的典型矿石样品进行分析,并从矿石类型、组构、矿石矿物成分、化学成分等四个方面对矿石特征进行了系统研究。发现在矿床形成过程中交代作用显著,说明成矿过程中热液作用占主要优势,进而通过形成的具有指示温度范围的矿物及矿石组构的特点,为矿床成因及成矿期次的划分提供一定的理论依据,根据矿石的组构,蚀变情况,矿石矿物成分等特征可初步推断此矿床为中低温热液矿床。
Taiyanggou Lead and Zinc Deposit in Sichuan Mianning is located in northern section of Xikang Yunnan axis. This paper analyzes the typical ore of mining system and makes a systematic study to ore characteristic from four aspects： ore types, petrofabric, mineral composition of ore and chemical composition.According the four aspects, found in the process of deposit, formation metasomatism is remarkable, which indicates hydrothermal process had played a major advantages in the process of deposit. Then by the forming has instructed the characteristics of the temperature range of minerals and ore fabric,which provides a theoretical base for the genesis of ore deposit and partition of metallogenetic period and stage. Through the characteristic of petrofabric, alteration, and mineral composition of the ore, we can preliminaryly infer this deposit is a mesothermal-low temperature deposit.
