摘　　要：通过综合分析金川南延地区的岩石学、地球化学和地球物理特征,对其成岩环境、构造背景及基性超基性岩浆活动规律进行了调查研究,并与矿区含矿超基性岩体进行了对比,进一步深化了对金川地区成矿地质特征的认识。结合物化探工作,在研究区内圈出2个Ⅰ级综合异常区及2个Ⅱ级综合异常区,认为该区找矿前景良好,是进一步找矿的重要靶区。Such information as digenetic environment, tectonic setting and basic-ultra basic magma activity rules were investigated through comprehensive analysis of the petrology, geochemistry and geophysics features in Nanyan of Jinchuan area, and then comparative study were carried out with the basic-ultra basic rocks in Jinchuan deposit. All works above make the ore-forming geological characteristics further understood in Jinchuan area. Combined with geophysical and geo- chemical exploration work, two I level comprehensive abnormality areas and two 1I level comprehensive abnormality areas were circled into the research area. It is considered that these areas have good the ore-prospecting vision, and are the important ore-prospecting directional and target areas.
