最主要的金矿床类型概述及其普查找矿方法介绍

本文提出的九种类型金矿床,是目前我国最主要的普查-勘探对象,其中特别详细介绍了卡林式金矿床、团结构式金矿床、焦家式金矿床和东风山式金矿床。对于分布广、数量多,与有色金属伴生的金(银)矿床,着重指出了其利用的前景。这样,可使一矿变多矿、小矿变大矿,甚至遍布全国的有色金属矿山开采的废石、废渣也有可能采出金(银)。对全国各省(区)金的主要来源的砂金矿床和脉金矿床,也给予很高评价与重视。本文还就找金的方法,提出了地质-物探-化探-遥感综合方法,还介绍了国外对低品位金矿常用的氰化物溶液堆浸处理法,提取金和在水中鉴定金痕量的超灵敏度找矿法。

SUMMARY OF THE MAJOR TYPES OF GOLD DEPOSITS AND ITS PROSPECTING METHOD

This paper introduces nine types of gold deposits which are the main objects of gold-prospecting in our country at present among. Among the gold deposits specially introduced are carlin type, solidarity Tunnel type, jaojia type and east wind mountain type.All those are widely spread, grent in number and associated with non-ferrous metals are given the emphasis on their available prospects. Thus one deposit can be turned into more, smaller deposits can be changed into bigger ones and gold (silver) even from barren rocks and barren slags which are mined from the non-ferrons mines thronghout our country are probably extracted. High valuation and great attention are also given to placer gold deposits and vein gold deposits, which are the main sources of gold in the different parts of our country. Varions gold-prospecting methods are also introduced in this paper.
