| 摘 要： | 营口地区印支期花岗岩为Ⅰ型（同熔型）花岗岩，燕山期花岗岩为S型（陆壳改造型）花岗岩。印支期花岗岩是造山运动晚期岩浆作用的产物，岩浆来源于深部。燕山期花岗岩是与燕山期造山运动同构造期岩浆作用的产物，岩浆来源于浅部。金矿床的形成主要与印支期次碱性二长花岗岩岩浆作用有关。

| Abstract: | By studying the geology, petrology, petrochemistry and geochemistry of Mesozoic granitoids in Yingkou district, the authors believe the similarities.between Indosuiian granitoids in the studied district and I -type granite defined by Chappell and White,and between the Yanshanian granitoids and S -type granite in petrology .petrochemistry and geochemistry. The forming environment of ihe granitoids and its relationship with gold mineralization are discussed on the basis of the study of petrochemistry,Pb -isotope and gold content. The gold mineralization in this area is believed to be related to Indosinian granitic magmatism. |
