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。  

关键词: 基性超基性岩体, 地质特征, 地球化学, 找矿远景

Abstract: 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 geochemical exploration work,twoⅠ level comprehensive abnormality areas and two Ⅱ 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.

Key words: Basic-ultra basic rock, Geological characteristics, Geochemistry, Ore-searching prospects
