卡林型金矿最早于上世纪六十年代美国内华达州发现,到目前为止,其历史储量、资源量、产量总和占所有金矿的4%,年产金量占全球总产量的9%(Frimmel,2008)。与其他类型金矿床相比,其特点主要为:金颗粒呈显微-次显微级,不可见,矿石成浸染状,主要赋存与碳酸盐岩建造中。卡林型金矿理论于上世纪70年代中后期传入我国后,相继在陕西、贵州和湖南等地均有发现(刘东升,1985)。目前,我国卡林型金矿主要分布在陕甘
The Carlin-type gold mine was first discovered in Nevada in the 1960s in the United States. So far, its historical reserves, resources and output account for 4% of all gold mines and its annual gold output accounts for 9% of the global output Frimmel, 2008). Compared with other types of gold deposits, the main features are as follows: the gold particles are microscopic-submicroscopic and invisible, and the ores are disseminated and mainly occur in carbonate rock construction. Carlin-type gold mine theory was introduced into China in the late 1970s and successively discovered in Shaanxi, Guizhou and Hunan (Liu, 2005). At present, Carlin-type gold deposits in China are mainly distributed in Shaanxi and Gansu
