| Abstract: | During the 1:50 000 mineral resource prospect investigation in the Mahonondor area of East Ujimqin Qi,Inner Mongolia,the authors firstly divided the Baoligaomiao Formation into two rock unite members: the lower member is made of the andesites,andesitic volcaniclastices and sandstone-conglomerates,and the upper member consists of the rhyolites,dacitic tuff,carbonaceous slate and the fluvial deposit sandstone-conglomerates.In this study,zircons were chosen from the andesite,rhyolites and dacitic tuff to analy... |
