【摘要】 本文通过对燕山地区中生代花岗岩的物质成分和地质环境的研究，确认其构造环境是处于大陆板块内部，岩浆主要来源于下地壳，并将其划分为四个系列：即黑云母花岗岩系列、二长花岗岩系列、闪长岩－花岗岩系列，碱性花岗岩系列，其中二长花岗岩系列与金矿关系密切，闪长岩-花岗岩系列与铅锌矿关系密切。更多还原

【Abstract】 Researches on the composition and the geologic setting of the Mesozoic granite in Yanshan Area shows that granite in this area was formed in the tectonic setting of the inner Continental plate. The granite can be classified into four series, biotite-granite series (Ⅰ). Adamellite granite series(Ⅱ) .diorit-granite series(Ⅲ) and alkali granite series(Ⅳ). Series (Ⅱ) is closely related to An mineralization while serie (Ⅲ) is closely related to Ph and Zn mineralization.更多还原
