Abstract:The northern Penglai area is located at the northern end of QixiaDaliuxing gold belt in Jiaodong gold concentration area. There are a series of gold bearing quartz vein type gold deposits and alteration rock type gold deposits in fracture zone. Taking typical gold deposits in Xujiaji ore field and Longshandian ore field as research objects, 3d geological modeling has been introduced by using Creatar XModeling software, and orefield scale rock mass, fault structure and alteration zone models have been constructed based on regional geological profile, gravity and magnetic combination profile, CSAMT profile and exploration engineering data. The threedimensional geological model of typical deposit has beem established in order to realize the visualization of orebody and provide basis for deep prospecting of typical deposit.
