| 摘 要： | 泰莱幔枝构造包括幔枝核部(岩浆-变质杂岩)、外围沉积盖层中的拆离滑脱构造和上部幔枝上叠构造三部分构成。认为泰安—莱芜地区铁金铜矿找矿突破很大可能在泰莱幔枝滑脱层构造中,也可能是寒武系、奥陶系中的隐爆角砾岩型金矿或夕卡岩型金矿;崅峪岩体近EW向与近SN向交汇处为含矿流体活动主通道,EW向构造成铁矿,崅峪岩体深部可能有大规模铁矿;NNW向构造成金矿,崅峪岩体中部深处可能有富金矿。

| Abstract: | Mantle plume branch structure in Taian-Laiwu area includes its core (magamatic-metamorphic complex),detachment fault in the surrounding and sedimentary cover and overprinted structure at the upper of the mantle plume. Breakthrough in the ore prospecting in the area will made in the detachment layer. Cryptoblast breccias type gold deposit or skarn type gold deposit may occur in Cambrian, Ordovician strata of the layer. Intersection of EW and NS structure at Jiayu intrusive body may be the main passage of ore fluid. Iron ore deposit may occur in the EW structure and big iron deposit at depth of the intrusive body. In NNW structure may occur gold deposit and rich gold ore deposit at middle-deep part of body. |
