摘要
海沟花岗岩体为一个由斜长花岗岩、二长岩及二长花岗岩侵入体构成的复式岩体，是燕山早期花岗岩浆演化不同阶段相继侵入形成。该岩体与金矿是“兄弟”关系、“同源”关系，因此，金矿的同源花岗岩是重要的找矿标志。
The Haigou granitic body is a compound one which was formed by plagiograite, monzoite, adamellite intrusives, which was intruded in succession in different stages of early Yanshan granitic magmatic evolution. The relationships between rock bodies and Au deposits are “brother”or“kindred”, therefore, the cognate granite of Au deposit is an important prospecting criteria.
