一、概述在一般金矿床中,金在矿石中的含量极少(0.n～ng/t),因而金的存在,不能使含金岩体呈现出明显的地球物理特征。但是与金伴生,共生或相关的某些元素如Ag、As、Bi、Pb、Zn、Cu、Sb、Te、Mo、Hg、Fe、W、Ba、U、Th、K等往往具有较高的含量,因而金的勘查可通过寻找与金矿有关元素的原生晕、次生晕、分散流的分布规律、富集程度、间接寻找金矿。我国目前已找到与Cu、Ag、Mo,Ni、Pb、Zn、Fe、 I. General In general gold deposits, the content of gold in the ore is extremely small (0.n ~ ng / t), so the presence of gold can not make the gold-bearing rock show obvious geophysical characteristics. However, some elements such as Ag, As, Bi, Pb, Zn, Cu, Sb, Te, Mo, Hg, Fe, W, Ba, U, Th, K and so on that are symbiotic with or associated with gold tend to have higher Therefore, gold exploration can find the gold mine directly by looking for the primary halo, secondary halo and the distribution of scattered flow and enrichment of gold-related elements. China has now found and Cu, Ag, Mo, Ni, Pb, Zn, Fe,
