中国胶东地区巨量金矿成因的一种新解释:地幔气柱成矿机制OACHSSCD

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 core-mantle 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.
