乌日尼图钨钼矿矿床特征与早白垩世花岗岩的关系
|
摘要
通过对内蒙古苏尼特左旗乌日尼图铜铅锌钨钼矿地质背景、矿床地质特征、矿床成因类型、岩石化学特征的研究,总结归纳了乌日尼图钨钼矿与小型中酸性岩体的成矿关系、围岩对成矿的控制作用、围岩蚀变类型与成矿的关系、钨钼等多金属矿的地球物理、地球化学特征,以及矿床的区域展布和时间演化规律.指出中生代早白垩世中酸性岩体为本矿区的矿源体,且该岩石类型亦为二连-东乌旗-梨子山成矿带上钼矿的重要矿质来源,是内蒙古草原覆盖区寻找钨钼多金属矿应重点关注的岩石类型.
The geological settings,geological characteristics,petrochemical features of tungsten and molybdenum ore deposits in Wurinitu of Sunitezuoqi,Inner Mongolia,are studied in detail,metallogenic relationship between the characteristics of tungsten and molybdenum ore deposit in Wurinitu and that of small neutral and acid rock bodies is explored and the controlling effect of its wall rocks on the mineralization is discussed,and the relationship between the alteration types of the wall rocks is also probed.In addition,geophysical and geochemical features of tungsten and molybdenum deposits,the distribution and evolution laws of the deposits are presented in this paper.It is found that neutral and acid rock bodies in Early Cretaceous granite are source rocks for the metallogenic belt in Erenhot-Dongwuqi-Lizishang and is promising for future tungsten and molybdenum mineral exploration in the grassland of Inner Mongolia.
