In this paper, the geological features of Shaolahazi alkaline rock bodies and alteration and mineralization in the southern part of Jiaohe region were studied through detailed geological survey, and found that the rock has a good niobium. By scanning electron microscopy to determine that the ore mineral with niobium tantalum is brown yttrium niobium, it provides the basis for the dressing;combined analysis of the regional geological conditions, it is considered that the alkaline complex in the Dunmi fault zone of central part of Jilin Province is an important target for prospecting rare element minerals.
