| 摘 要： | 目前,对辽东营口虎皮峪地区早元古宙条痕状花岗质岩石成因有两种认识,一是认为属混合交代成因;二是认为属幔源岩浆型花岗岩。作者通过对虎皮峪条痕状花岗质岩体地质特征,岩石学及岩石地球化学研究,认为虎皮峪条痕状花岗质岩石为重熔型花岗岩。形成于辽河旋回,是辽河群下部火山—沉积岩在热动力作用下发生重熔形成再生岩浆,然后就地固结或沿着地壳薄弱部位上侵形成岩浆型花岗岩,具有S型花岗岩特征

| Abstract: | At present,there are two kinds of understanding to origin of Early Proterozoic streaky granitic-rocks from Hupiyu in Yingkou of Liaoning:one is of migmatic- metasomatic type;the other is of mantle-derived magma type.Through the study on its features of geology,petrology and geochemistry,the authors hold that it belongs to remelting type,which volcano-sedimentary rocks in Lower Liaohe Group occured remelting into regeneration magma under the effect of thermodynamices,then consolidated on the spot or intruded along weak position of.crust,forming magma-type granite rocks,having features of S-type ones. |
