摘要
本文从岩浆演化、岩浆岩矿物成分、化学成分、微量元素、稀土元素等方面论述了三家子金矿区的侵入岩是由基性、中性、酸性岩构成的钙碱性岩石系列，这一岩石系列与其东部火山岩为同源产物，其原生岩浆来源于上地幔。岩浆演化机制是以分离结晶为主导，在岩浆演化到晚期花岗质岩浆结晶的末期时形成岩浆热液型金矿床。
This paper discusses characteristics and genesis on the basis of evolusion, mineralogy, chemical composition, micro-elements, REE distribution patterns of magmatic rocks in shan jiazi gold Mine.A conclusion is made that the intrussive rock is composed of basic,intermediate and acid rocks (calcalkalic rock series) which are cognate with volcanic rocks to the east deriving from the upper mantle. The evolution mechanism is dominated by separating crystallization. Gold ore was formed at the late evolution of granitic magma crystallization
