摘要
新近发现华北地台金伯利岩中存在自然铁、自然铜、自然锡、硅铁石、二硅铁矿、未命名的Si、Fe、Ti互化物及含铬黑镁铁钛矿等前人未曾报导过的矿物。据初步研究,它们与处于强还原环境的地幔深层流体有关。这些矿物的发现,首次为软流层中的流体交代作用提供了实物证据。
Some minerals which were not reported in kimberlites have recently beenfound in kimberlites of the North China platform. Tbey are native iron, native copper, native tin, fersilicite, ferdisilicite, unnamed mineral consisting of Si, Feand Ti, and chromian kennedyite. A preliminary study shows that they arerelated to deep fluids of the mantle in a strong reduction environment. Thedisoovery of these minerals provides evidence for fluid metasomatism in asthe-nosphere.
