摘要
桓仁夕卡岩型多金属矿床受控于寒武纪灰岩与燕山期闪长杂岩体接触带之间的夕卡岩.矿物成分多样,结构构造复杂,围岩蚀变强烈,矿化分带明显.对桓仁矿床的空间分带特征进行了的探讨,并选取了不同深度的穿透岩体及矿体的典型穿脉作为研究对象.通过岩石类型的划分和金属元素的测试,并结合其他地质特征,分析讨论了矿体、岩体在水平及垂直方向上的分带规律.详细讨论了不同金属元素的空间赋存性,并在此基础上总结了该矿床的成矿规律,为今后在其的深部、边部找矿提供理论依据.
The Huanren skarn-type polymetallic deposit is controlled by the skarn in the contact zone between Cambrian limestone and diorite complex body. It is characterized by complicated mineral compositions and ore fabrics, intensive wall-rock alteration and distinct mineralization zoning. With classification of rock types, test of metal elements and other geologic characteristics, the regularity of the horizontal and vertical zonation of the ore bodies and rocks is analyzed. The spatial occurrence of different metal elements is particularly studied in detail. On this basis, the metallogenic law of the deposit is summed up, which makes a theoretical preparation for the prospecting in deep and outer areas.
