摘要：Focusing on Xiadian gold deposit in Jiaodong Peninsula, this paper examines the metallogenic information of faults and alteration zone by 3D geological modeling and 3D spatial analysis. Specifically, the geological setting of the gold deposit was reviewed before setting up 3D geomodels on alteration zone field and geologic morphology. Then, the ore-controlling factors were subject to quantitative analysis, including alteration zone field, the fault slope, the fault convexity, the fault concavity, the change from steep to flat and the change from flat to steep. It is concluded that the formation of Xiadian gold deposit involves several ore stages; the gold is more likely to deposit in fault zones of steep-to-flat transformation (4 to 8 rad), with slope between 40° and 50° and undulation between 0m and 20m; the tendency May be attributed to the fluid flow and the physicochemical change of the mineralizing environment. This research highlights the importance of the occurrence exchange of fault zones in future mineral explorations. Copyright ? 2017, AIDIC Servizi S.r.l.
