通过对南秦岭印支期胭脂坝、东江口和柞水花岗岩岩石学、地球化学特征及多金属成矿地质特征；的分析研究表明，三个岩体均属于高钾钙碱性岩石系列，胭脂坝黑云母花岗岩具过铝质A型花岗岩类特征，与钼成矿作用关系密切；东江口岩体和柞水岩体具准铝质-弱过铝质I型花岗岩类特征，与金及铅锌成矿关系密切。成矿类型以热液蚀变岩型和接触交代型为主。
通過對南秦嶺印支期胭脂壩、東江口和柞水花崗巖巖石學、地毬化學特徵及多金屬成礦地質特徵；的分析研究錶明，三箇巖體均屬于高鉀鈣堿性巖石繫列，胭脂壩黑雲母花崗巖具過鋁質A型花崗巖類特徵，與鉬成礦作用關繫密切；東江口巖體和柞水巖體具準鋁質-弱過鋁質I型花崗巖類特徵，與金及鉛鋅成礦關繫密切。成礦類型以熱液蝕變巖型和接觸交代型為主。

Based on analysis and researches on granite petrology, geochemistry and polymetallic mineralization features, three Indosinian granite bodies occurring in the south Qinling are attributed into K eale-alkaline rock series, including the Yanzhiba biotite granite with characteristics of peralu-minous A-type granitoids, which are closely associated to molybdenum mineralization, the Dongjiangkou and Zhashui granite bodies with features of metaluminous - weakly peraluminous I-type granitoids, closely assoeiated with gold-lead-zinc mineralization. The metallogenic types in this area are dominant in hydrothermal altered rock and contact metasomatie types.
