摘要
为了解辽西兰家沟地区含钼花岗岩岩石化学的基本特征,在采用C IPW标准矿物计算法获得标准矿物重量和体积百分数的基础上,对该区岩石的命名、碱度的确定、系列的划分、分异作用、板块构造环境以及花岗岩的成因分析等几方面进行了分析判别,认为该地区的花岗岩为岩浆成因的、高度分异的钙碱性系列酸性—超酸性铝过饱和型二长花岗岩。
To understand the West Ravine area of liaoning province molybdenum basic characteristics of granite rocks,minerals in the calculation used to obtain the standard CIPW standard weight and volume percentage of minerals,based on the naming of rocks in the area,the determination of alkalinity,the series division,differentiation,plate tectonics and granites of the environment,such as several aspects of the analysis determine that the area for the magmatic origin of granite,highly differentiation of calc-alkaline to acid,aluminum acid-super-saturated type II long granite.
