Abstract: Through 5 years deep exploration in Jiaojia metallogenic belt of Shandong province,a super large-scale altered rock type gold deposit,which is located in the depth of Sizhuang mining area in north of Jiaojia metallogenic belt,is founded by No.6 Exploration Institutes of Geology and Mineral Resources of Shandong.There is 100～250m vertical in terval no ore space between newly founded deep ore and shallow ores of Sizhuang mine. Three ore-bearing rock zones have been classified and three gold ore body groups with 163 ore bodies have been circled1 Among them,large scale Ⅰ-1 in sidious ore body has been found in beresitized cataclastic rock belts,the proportion of gold resou rcesis 39.39%,and great break through in ore probing has been gained as well. The paper deals with geological features of Sizhuang mining a rea and geological features of Sizhuang gold depositetc. It is of great theoretical and practical significance.
