Three-dimensional Modeling of Deep Metallogenic Structure in Northwestern Jiaodong Peninsula and Its Gold Prospecting Significance
      The northwest area of Jiaodong (east Shandong) is the biggest gold ore concentration area in China. In recent years, great achievements have been made in the exploration of deep resources. Deep exploration shows that the production regularity of deep gold orebodies in northwestern Jiaodong is consistent with that in the shallow part, i.e., they are strictly controlled by regional strike-slip faults. Therefore, the reserve increase of deep resources largely depends on the understanding of the form, distribution and structure of deep metallogenic structure. This paper proposes a three-dimensional modeling method for deep metallogenic structures. Rudimentary models of Sanshandao, Jiaojia, and Zhaoping faults, as a basic deep structural frame, were firstly constructed by combining shallow modeling with deep inference through utilizing geological, geophysical and geochemical exploration data. Based on the models, deep models for these faults (with depth up to 3000 m) were further refined via the multi-source data coupling processing approach to decrease uncertainty and bias sourced from individual structure inferring. Based on the three-dimensional models of deep metallogenic structure, the 12 prospecting targets of deep gold deposits in the study area were delineated, which is of great significance in guiding deep prospecting.
