各种类型的金矿床，在世界总储量中所占的比例，依次为：变质砾岩型56.2%，变质热液型12.4%，伴生金9.5%，沙金8.9%，岩浆热液型及火山热液型7.0%，热水溶滤型0.9%。 从全球范围来看，按金矿产出的大地构造单元来分，又可分为四类：地盾成矿区、地台及边缘成矿区、地槽褶皱带成矿区和环太平洋成矿带。其中，产于地盾的金储量，占世界总储量的25.6--27.8%；古地台盖层局部中生代活化区，占1.1--1.3%，优地槽区，占12.9--15.6%；冒地槽区，占1.1--1.2%；而古地台盖构造区，则占47.1--47.7%。历史最悠久埋藏最深的金矿海水中也可淘金矿
Various types of gold deposits, which accounted for the proportion of total reserves in the world, is as follows: metamorphic conglomerate type 56.2%, metamorphic hydrothermal type 12.4%, associated gold 9.5%, gold 8.9%, magmatic hydrothermal type and volcano hydrothermal type 7%, hot water leaching type 0.9%. From a global perspective, the tectonic units of gold deposits to points, can be divided into four categories: shield metallogenic zone, platform and marginal mineralization area, geosyncline fold belt metallogenic region and the circum Pacific metallogenic belt. Among them, produced in the shield of gold reserves, representing the world's total reserves of 25.6--27.8%; the platform cover local Mesozoic activation area, accounting for 1.1--1.3%, accounting for 12.9--15.6%; eugeosyncline area, geosyncline area, accounting for 1.1--1.2%; and the ancient platform cover tectonic zone, accounted for 47.1--47.7%. The longest buried gold deposits in the deepest gold mine can also be gold mine
