在中国胶东地区,焦家、玲珑、三山岛等3条主要成矿控矿断裂构造,分别控制着千t以上的黄金储量;2025年在莱州市三山岛北部海域新发现国内唯一、亚洲最大的海底巨型金矿。然而,金属于稀有贵金属(地壳中丰度值仅为3×10^-9),又是惰性元素,如何能够形成如此之大的超巨量堆积(且其最高品位可达百分比级别)?可能的解释是源自核-幔界带D″层的地幔(超临界态)气柱,类似于地球大气层中形成的龙卷风——其巨大的中心负压甚至能将海水与鱼虾一起卷上天空,地幔气柱则可将D″层中高浓度含金流体卷入其中,穿越下-上地幔,直达地壳,形成超大规模金矿。由此推断,地球上某些超巨量金属矿床的成因均可能与此有关,这是个很值得探索的命题,论文将其命名为“地幔气柱”成矿机制,以与传统“地幔热柱”成矿机制相区别。

In the Jiaodong region of China, three major ore-controlling fault structures—Jiaojia, Linglong and Sanshandao—respectively control gold reserves exceeding one thousand tons.In 2025, the northern offshore area of Sanshandao in Laizhou City had discovered the country's only, and Asia's largest, submarine giant gold deposit.However, gold is a rare precious metal(with a crustal abundance of only 3×10^-9) and is an inert element.How could such a massive supergiant accumulation form, with peak grades reaching percentage levels? One possible explanation is that it originates from a mantle gas-plume in the D " layer at the coremantle boundary, similar to a tornado formed in Earth's atmosphere which has enormous central negative pressure could even lift seawater along with fish and shrimp into the sky, while the mantle gas-plume could entrain high-concentration gold-bearing fluids from the D" layer, transporting them through the lower to upper mantle, directly into the crust, forming ultra-large gold deposits.It is thus inferred that the formation of certain supergiant metal deposits on Earth may be related to this mechanism.This is a highly intriguing topic worthy of exploration.The paper terms this as the " mantle gas-plume" mineralization mechanism to differentiate it from the traditional " Mantle Plume" mineralization mechanism.
