摘要
燕山地区内生金矿床分为 5类 (其中产于侵入岩和变质岩中的金矿床是最重要的类型 ) ,具显著的区域成矿学特征 :明显分为密云—青龙和尚义—平泉南北两个金矿成矿带 ;内生热液成矿期主要分为 4个成矿阶段 ;成矿时代主要为燕山期 (150~ 2 0 0Ma)
Gold deposits in Yanshan district are divided into five types( the gold deposits occurred in intrusive rocks and metamorphic rocks are the dominate ones),and have remakable metallogeny features:they are divided into south gold mineralization belt(the Miyun to Qinglong belt) and north gold mineralization belt(the Shangyi to Pingquan belt); the endogenetic hydrothermal solution mineralization period is mainly divided into four mineralization stages; the major mineralization is Yanshan era(150~200 Ma).
