摘要
湘南地区印支、燕山期各类岩体呈环形或似环状分布，且燕山期岩体进一步向潜火山口收缩。这些岩浆岩有基性、中性、中酸性、酸性和碱性，它们来自幔源、壳源、或壳幔混源，是地幔柱（热点）控制出现的热岩系。岩浆迁移过程中除自身的成矿元素外，还使围岩中相应的成矿元素活化转移，共同铸成现今的矿床。
The various Indosinian-Yanshanian rock mass in south Huan area are annular,and the Yanshanian rock mass contracted further to subcraters.These magmatic rocks,including basic,intermediate,intermediate-acid,acid and alkaline rocks,came from earth's crust and mantle and these both and were controlled by the mantle plume(hot spot).In the process of magma migration,the metallogenic elements in country rocks were mobilized.These elements together-with the metallogenic elements in the magma result in forming the present deposits.
