Geological conditions for ore-forming process and prospecting direction of the U-Mo polymetallic deposits in Guyuan volcanic basin

Guyuan volcanic basin is an important base for exploring U-Mo polymetallic deposits and mining development in northern China.Based on the geological characteristics of the deposits,the study has analyzed ore-forming geological conditions,mineralization characteristics,and the relationship between metallogenic epoch with mineralization and Mesozoic sub-volcanic rocks with fracture structure.The study believed that a great prospecting perspective should be there if we prospected for strata-bound Pb-Zn-Ag-Au deposits that were overlapped and altered by magmatic hydrotherm in basement metamorphic rocks of the basin,and prospected for volcanic rocks-host hydrothermal U-Mo deposits in caprocks of the volcanics in the basin.
