摘要：

对马泉金矿载金矿物金含量和金矿物种类、大小及金的存在形式等进行了系统总结。通过对褐铁矿中Fe2O3 与Au 含量的对比研究,毒砂中Au 与As 含量的论证,黄铁矿特征及与Au 矿化的关系的论述,Au、Ag、Sb、Pb 与铅(锑) 矿物类(含方铅矿、辉锑铅矿、硫锑铅矿等) 的相互关系的论证后认为马泉金矿床主要载金矿物为褐铁矿、毒砂和黄铁矿,次要载金矿物为石英等。矿石中的银来自锑铅矿物类。在地表找矿中,褐铁矿(赤铁矿) 化可作为找矿标志;深部找矿中,毒砂、黄铁矿可作为找矿标志。

关键词: 褐铁矿, 毒砂, 黄铁矿, 锑铅矿物类

Abstract:

Make a systematic summarize of the kind and size of the Au mineral, content of the Au mineral and the exist form of Au. Thought the study of comparing the content of Fe2O3 and Au in the limonite, demonst rating the content of Au and As in the arsenopyrite, discussing the relation between characteristic of pyrite and mineralization of Au, relation of Au,et al,draw a conclusion that Maquan gold deposit main mineral are limonite, arsenopyrite, pyrite ,minor mineral are quartz,et al. Ag in the mineral is from the mineral of Sb and Pb. Seeking on the earth’s surface, mineralization of limonite can be looked as the symbol,into the deepth , arsenopyrite, pyrite can be looked as the symbol.

Key words: limonite, arsenopyrite, pyrite, mineral of Sb and Pb
