元古宙金属矿床的主要类型除少数著名矿床外,元古宙金属矿床都产在层状沉积岩或火山岩内,或产在它们的变质产物中,这些矿床与它们容矿岩石是明显一致的。元古宙金属矿床的这种一致特征与晚显生宙矿床的主要特征明显相反,并且由此而得出成矿系统的特征随着地质时代不同而发生重要变化的意见。我丢弃了这种概念。晚显生宙的科迪勒拉型矿床(例如斑岩铜矿、矽卡岩型和脉型矿床)是在陆上会聚弧形环境的浅部就位的,它们在发展中的较古老地体内逐渐稀少,在逻辑上可认为是这些弧形系统浅部位置被剥蚀的结果。
The main types of Proterozoic metal deposits Except for a few well-known deposits, the Proterozoic metallogenic deposits are produced in stratiform sedimentary rocks or volcanic rocks or in their metamorphic products, which are in clear agreement with their hosted rocks. This consistent feature of the Proterozoic metallogeny contrasts with the main features of the Late Phanerozoic deposit, and from this it is concluded that the characteristics of the metallogenic system change significantly with the geological age. I dropped this concept. Late Pleistocene Cordillera deposits (such as porphyry copper deposits, skarn-type and vein-type deposits) are located in the shallow parts of onshore converging arcuate environments, and they are undergoing development in the more ancient Gradually scarce in the body, logically can be considered as the shallow system of these arcuate system erosion results.
