这类矿床主要形成于中新元古代的裂谷系和裂谷系边缘的不同地质构造单元,其分布受构造控制,集中分布于华北陆块北缘东、中、西段元古宙裂谷系和扬子陆块西侧康滇地轴震旦系裂谷带东侧的边缘活动带,并以华北陆块北缘为主;成矿作用总体受火山-沉积-变质作用控制,具层控性;成矿时代有从北向南变新的趋势。

Most of the large gold and polymetal deposits distributed in the north margin of the Yangtze platform located in the nuclei of old rift system.
扬子地台北缘大多数金矿床集中在裂谷系古陆隆起内外接触处，经历了复杂的地壳构造演化，形成新的金矿类型和矿化组合，具多源性，以深源为主，浅源次之，再次是陆源，控矿构造包含同生构造与封闭聚矿盆地等多种成矿作用的叠加。

自19世纪70年代板块构造理论引入中国后,一些学者把拗拉槽(Aulacogen)一词赋予了鄂尔多斯盆地西缘贺兰山地区,并认为贺兰山、秦岭、北祁连中新元古代至早中寒武世为裂谷发育阶段,秦岭、北祁连、贺兰山构成了三叉裂谷系。
