摘要
广西海洋山花岗岩基侵位于海洋山复式背斜核部， 形成于晚志留世。岩基划分为４ 个单元， 归并为１个超单元， 建立了海洋山花岗岩岩石谱系单位。岩石学、岩石化学、微量元素及稀土元素地球化学特征表明，海洋山超单元各单元为壳源重熔型花岗岩浆不断分异演化的产物。花岗岩基为一大型复式含矿岩体， 与Ｗ、Ｓｎ、Ｓｂ、Ｐｂ、Ｚｎ
The Haiyangshan granitic mass was intruded in the core of anticlinoria and formed in the late Silurian.The granitic mass was divided into 4 units,which were grouped into a superunit,and the lithodemic units of granitoids in Haiyangshan is established. The characteristics of petrology,petrochemistry and trace element and rare earth element geochemistry reflected that every unit in the Haiyangshan superunit are the products of continuous differentiation and evolution of granitic magma of crustal remelting type .The granitic mass is a ore-bearing rock mass, which is close relation with W, Sn, Sb, Pb, Zn etc.mineralization.
