地慢柱与热点的成矿作用

地幔往与热点是当今地质学前沿课题之一，但研究程度较低，国内更是刚刚起步。本文从时空演化的角度探讨了地幔柱一热点的成矿作用。地幔柱与热点既可见于板块内部，也可见于洋中脊和造山带等板块边界，既可见于现代更可见于古代，因此它可能影响到地表各处以及地史上各阶段的成矿作用．而且在其自身演化的各个阶段都有不同类型的矿化特征。已知的矿床类型包括锡、铜、铅锌、铀、稀土及宝石等。我国华南东钨西锡、东老西新的成矿规律、二叠纪峨眉山玄武岩、白云鄂博稀土矿以及阿尔泰与碱性岩有关的锡多金属成矿系列等，都可能与地幔柱－热点作用有关。

Mineralizations Related to Mantle Plume and Hotspot

The mantle plume and hotspot tectonics is a frontier topic for the modern geology,however, it has been researched poorly by now even in China. This paper discusses the mineralizations related to the Inantle plume and hotspot in view of its evolution and distribution. Mantleplume and hotspot may be located whthin a plate or on the boundary of plates, and may occurpresently or anciently, so they can influence mineralizations in different part of the crust and indifferent evolution stages of the earth history. preside this, there are different kinds of mineralization in different stages of the mantle plume. Related mineral deposits Include tin, copper, lead analzinc, rare earth element, gemstone and so on. The characteristics of east wolfram west 'tin and eastold west young for the mineralizations in south China, the Emei basalt of Permian, the llayan oboREd deposit, and the tin--poly--metallogenetic series associated with alkallc igneous rocks in Altayorogeny may be related to mantle plume--hotspol tectonics.
