摘要
“焦家式”金矿(即破碎带蚀变岩型金矿)是山东胶西北地区重要的矿床类型。莱州寺庄金矿床位于焦家成矿带的南段,矿化特征表现出与该成矿带上诸金矿的共同特征。矿区内划分了3个赋矿岩性带(黄铁绢英岩化碎裂岩带、黄铁绢英岩化花岗质碎裂岩带、黄铁绢英岩化花岗岩带),圈出3个矿体群(共180余个矿体)。其中在黄铁绢英岩化花岗岩带内发现了规模较大的矿体,取得了重大的找矿突破。
＂Jiaojia＂ type gold deposit （i. e. cataclastic- altered rock type gold deposit） is an important gold deposit type in Jiaoxibei area （northwest part of Shandong province）. Sizhuang gold deposit locates in the south section of Jiaojia gold- forming belt and has the same mineralization characteristics with Shangzhu gold deposit. Three ore--bearing rock zones have been classified（ they are beresitized cataclasite belt, beresitized granitic cataclasite belt and beresitized granite belt） and three gold orebody groups with more than 180 orebodies have been circled. Among them, large scale orebodies have been found in beresitized granite belts and great break through in ore probing has been gained as well.
