自70年代以来,人们越来越认识到,南美安底斯山地区许多矿床产于火山喷发中心,这是根据残留的层状火山、破火山口、复式火山穹丘、火山爆发口及古地热系统确定的.现在在南部秘鲁,西部波利维亚和北部智利的中安底斯地区的晚第三纪-第四纪火山杂岩中开采贵金属的许多采矿公司认为,中安底斯浅成热液金-银矿床与剥蚀的火山中心在空间上和成因上的关系是重要的.这个年青的火山杂岩覆盖了中安底斯成矿省大约三分之一的面积,该区大部分已知矿床是中新世或更 Since the 1970s, it has been increasingly recognized that many deposits in the Andes Mountains of South America are produced at volcanic eruption centers based on residual stratiform volcanoes, caldera, volcanic domes, volcanic eruptions, and paleolages System.Now many mining companies that exploit precious metals in the Late Tertiary-Quaternary volcanic complexes in the southern Andes of southern Peru, western Bolivia, and northern Chilean Chile believe that the Middle Andean epithermal It is important that the gold-silver deposit is geographically and genetically related to the denudated volcanic center, which covers about one-third of the area in the Central Andes mineralization and contains most of the known deposits Miocene or more
