所有的前寒武系分布区都明显的缺少浅成囊状贵金属矿脉和硅质泉华型矿床。这虽然是一个消极的因素,但都很重要。尽管世界上的浅成热液矿床分布十分普遍,但最重要的矿床都产在太平洋盆地四周;与板块边缘的消减及火山作用有关。这些各种各样的浅成热液矿床包括西太平洋火山岛弧的科希尔岛、博格拉和瓦图科乌拉;加利福尼亚海岸山脉带蛇缘岩套中麦克劳林硅质泉华金矿;内华达州的金矿床;以及美国西部陆相火山岩分布区的许多囊状金矿脉。
All of the Precambrian distribution areas are obviously lack of superficial cystic precious metal veins and Siliceous Quanhua deposits. Although this is a negative factor, both are important. Despite the widespread distribution of epithermal deposits in the world, the most important deposits are all around the Pacific Basin; they are related to the reduction of plate margins and volcanism. These various epithermal deposits include the islands of Kosher, Bogra, and Watucola in the western Pacific volcanic arc; the Maclaurin Siliceous Quanhua gold mine in the coastal zone of the California coast; The Nevada gold deposits; and many cystic volcanic veins in the continental United States volcanic rock distribution.
