Abstract:Jinxingtou deposit belongs to a skarn type Au-Fe polymetallic deposit, and associated with Ag, Cu and S. The main ore-forming body in Jinxingtou area is the late Yanshan Yinan series diorite complex. For a long time, the exploration work in this area is mainly in shallow part of Jinxingtou rock mass in the north, and its deep and peripheral prospecting work is relatively low. On the basis of summarizing metallogenic geological conditions in Jinxingtou area, geological characteristics and source of ore deposits, such as ore-forming rock body, ore body, ore controlling structure and alteration mineralization have been analyzed. Combining with analysis and analogy of regional metallogenic geological background of some gold deposits in western Shandong province, metallogenic potential and ore-bearing location in this area have been discussed. The north of Jinxingtou fault is key prospecting area. Based on the theory of metallogenic system, the deep and peripheral exploration work is carried out in the northwest, east and northeast areas of Jinxingtou rock mass for prospecting favorable ore controlling structures, and looking for various types of mineralization comprehensively, including explosive breccia type, magmatic hydrothermal type, contact metasomatic type and carbonate micro disseminated type. At the same time, the spatial distribution between the rocks and Jinxingtou fault in the area should be identified furthurly in order to guide the deep prospecting work in the peripheral and adjacent areas.
