摘要
分析总结区内地层、构造、岩浆岩与矿床的关系,矿区有利赋矿层位为中泥盆统棋梓桥组底部不纯灰岩,NE向成矿构造发育,燕山期花岗质岩浆活动强烈,成矿地质条件非常有利。将荷花坪锡多金属矿床类型分为矽卡岩—锡石硫化物型、破碎带蚀变岩型、蚀变花岗斑岩型三种,其中泥盆统棋梓桥组底部不纯灰岩中的似层状矽卡岩—锡石硫化物型矿床规模巨大,找矿前景非常可观。
The relationship of ore deposit with strata, structure and magmatie rocks in the region was analyzed in the paper, which shows that the favorable ore bearing stratum in ore field is impurity limestone on the bottom of Middle Devonian Qizhiqiao group when NE trending ore forming structure developed with strong Yanshanian granite magma activities and the geology was favorable for ore forming. The Hehua tin Polymetallic ore deposit types were divided into three types of ore deposit, namely skarn-cassiterite sulphide type, crush zone altered rock type and altered granitic porphyry type, in which the stratiform skarncassiterite sulphide type of deposit in impurity limestone on bottom of middle Devonian epoch is promising for further ore prospecting.
