摘要
河南毛堂金矿产于爆破角砾岩构造中,详查储量为小型矿床。爆破角砾岩构造是一种重要的储矿构造,产于其中的矿床通常是大型的。该文在介绍岩石化学特征、矿床地质特征的基础上,根据二号矿体载金矿物黄铁矿的形态分析,探讨了矿体的延伸,为深部找矿提供了矿物学依据。
The Maotang gold ore is a typical explosive breccia deposit. Its parent rock isgranite porphyry or Yanshan period. Tt belongs to cale-alkalic series. The struetural setting isof continental margin. The most important auriferous mineral is pyrite. in which the avcrage content is156.35g/t. Then in limonite the avcrage content is 24.77g/t. The pyrite mophlogical analysis shows that the ore body No.2 extends about 203m indepth. And this is the important mincral information for the deep prospecting work.
