摘要
金河-树河地区位于四川省盐源县,是四川省重要高品位铁矿石产地之一。基于此,根据《四川盐源县金河-树河地区矿产地质调查》的调查成果,对本区玄武岩各段岩性等特征进行总结,结合本区火山口、断层等分布特征,推导玄武岩浆不同阶段的活动特征。通过对本区主要矿床地质及分布等特征进行分析,综合玄武岩浆活动特征,认为华力西期岩浆喷发活动对本区主要类型铁矿成矿具有控制作用。
Jinhe-Shuhe area is located in Yanyuan county, Sichuan province, is one of the important high-grade ironore in Sichuan origin. Based on this, according to the " Mineral geological survey of Jinhe-Shuhe area in Yanyuancounty of Sichuan province" survey results, this area basalt lithology characteristics of each segment were summa-rized, according to the distribution features of volcanic crater and fault in this area, the active characteristics of differ-ent stages of basaltic magma were derived. Based on the analysis of the geological and distribution characteristics ofthe main ore deposits in this area, the characteristics of basaltic magma activity were analyzed. It is believed that theVariscan magmatic eruption had a control effect on the main types of iron ore deposits in this area.
