内蒙红花沟金矿有关岩石中金等微量元素的丰度及其意义

The abundance of trace elements as Au of related rocks in Hong-Hua-Gou Gold Deposit, Inner Mongolia and the significance of its study

本文首次系统地研究了内蒙红花沟金矿变质岩、花岗岩、石英斑岩和多种脉岩的Au、Ag等13种微量元素的丰度,并对其在矿源层研究和化探找矿工作中的意义进行了探讨。红花沟金矿各主要岩类的金丰度均在3.18～4.2ppb之间,斜长角闪岩的金丰度为4.2ppb,是金的矿源层。

In this paper, the abundance of the thirteen types of trace element as Au of related rocks such as metamorphic rock,granite, quartz-orthophyre and various vein rocks in Hong-Hua-Gou Gold Deposit are studied precedently and systematically.In addtion,the significance of its study to the research of source-bed and gold Prospecting by means of chemical exploration are discussed. The gold abundance of main types rock in this gold deposit fluctuates within the range of 3.18-4.2ppb while it is 4.2ppb for issite which is regarded as main source-bed of gold deposit.
