摘　　要：花山岩体是同源岩浆分异后,分四个亚期侵位而形成的复式岩体.是Ⅰ-型花岗岩出现锡矿化的典型例子。岩浆的强烈分异使各期岩体的岩石成分在时间和空间上出现了一个十分连续的演化系列,并形成了云英岩脉型锡矿化。Huashan composite batholith, composed of four granitic intrusions,is a typical example of composite comagmatic differentiates and tin- mineralization in Ⅰ-type granites. The strong differentiation of the magmacaused the different intrusions to show a progressive time and spatialevoltuionary series of petrographic compositions and the greisen-veinlet-type tin-mineralization. Also in this paper, by analogy, theauthors demonstrate the history of formation of Huashan batholithand analyze the mechanism of magmatic differentiation, magmaticevolution and tin mineralization in Ⅰ-type granites.
