云南的壳幔界面主体呈近南北向的复式地幔坳陷，其中发育有8条次级地幔坳陷带、10个地幔波台区，次级幔坳带及波台区控制了云南大型超大型金属矿床的生成、展布．通过把云南1800多个金属矿床（点）投绘在1∶2000000云南壳幔界面深度等值线图上，总结出云南大型超大型金属矿床的壳幔定位规律：矿床对称地展布在幔坳中心两侧的斜坡带上；大型矿床的幔坳距小于16 km、幔坳角小于1．1°；超大型矿床与大型矿床的幔坳距、幔坳角之间的关系符合黄金律0．618；幔坳角≤0．7°的波台是形成和寻找大型、超大型矿床的区域；同一条幔坳中可形成和找到多个超大型矿床；某些大型超大型矿床形成后受超壳断裂错动，其幔坳距、幔坳角均随之变大；云南95％以上的大型、超大型矿床分布在幔坳深度35～60 km 的范围内．
雲南的殼幔界麵主體呈近南北嚮的複式地幔坳陷，其中髮育有8條次級地幔坳陷帶、10箇地幔波檯區，次級幔坳帶及波檯區控製瞭雲南大型超大型金屬礦床的生成、展佈．通過把雲南1800多箇金屬礦床（點）投繪在1∶2000000雲南殼幔界麵深度等值線圖上，總結齣雲南大型超大型金屬礦床的殼幔定位規律：礦床對稱地展佈在幔坳中心兩側的斜坡帶上；大型礦床的幔坳距小于16 km、幔坳角小于1．1°；超大型礦床與大型礦床的幔坳距、幔坳角之間的關繫符閤黃金律0．618；幔坳角≤0．7°的波檯是形成和尋找大型、超大型礦床的區域；同一條幔坳中可形成和找到多箇超大型礦床；某些大型超大型礦床形成後受超殼斷裂錯動，其幔坳距、幔坳角均隨之變大；雲南95％以上的大型、超大型礦床分佈在幔坳深度35～60 km 的範圍內．

The Yunnan crust -mantle boundary is principally presented as a South -North composite mantle de-pression zone,including 8 developed secondary mantle depressions and 10 mantle bench areas,which have con-trolled the formation and distribution of large and super -large mineral deposits.7 crust -mantle positioning rules for Yunnan large and super -large metallic mineral deposits can be concluded through projecting these 1 800 plus deposits (points)onto the 1∶2 000 000 Yunnan crust -mantle boundary depth contour map:the de-posits symmetrically distribute along the slope at the lateral sides of the mantle center;crust -mantle distance and angle of large deposits are below 16 kilometer and 1.1°respectively;the relation between crust -mantle dis-tance and angle of super -large and large deposits comply with the golden rule of 0.618;the benches with a crust -mantle angle ≤0.7°are where large and super -large deposits were formed and can be found;multiple super large deposits can be formed and found within the same mantle depression;crust -mantle distance and an-gle of certain large and super -large deposits tend to increase under the impact of ultra -crustal dislocation after they were formed;over 95% of Yunnan large and super -large deposits distribute within the crust -mantle depth from 35 kilometre to 60 kilometer.
