摘要
本文重点介绍金刚石受大陆裂谷裂前岩石圈成穹阶段控矿的新认识,并对一些传统的成矿理论进行探讨,阐述了受大陆裂谷控制的金伯利岩的产生条件和时空分布规律。
It is proved that Kimberlites are formed at the stage of prerift doming of the crust by the connection between Kimberlites and continental riftings over parts in the world. Kimberlites are distributed in the uplifts and massifs beside the paleo continental rifts, which is in Keeping with the pattern of magmatic evolution in the rift zones. Kimberlites are normally found at the sholder of the rifts where carbonatites and alkaline complexes are abundent. The alkaline complex zones are commonly composed of them together. It is favourable to formation of Kimberlites that the rifting was of multiple generations on the same massifs. We have discussed some viewpoints of the conventional mineralogenetic theory for diamond.
