栖霞地区史家金矿地质特征及找矿浅析
|
摘要
山东栖霞史家金矿大地构造处于位于华北板块(Ⅰ)胶辽隆起区(Ⅱ)胶北隆起(Ⅲ)胶北断隆(Ⅳ)胶北凸起(Ⅴ)东部,南部与栖霞马连庄凸起(Ⅴ)接邻。区内沿新太古代栖霞序列与古元古界粉子山群接触带分布近EW向韧-脆性剪切带,糜棱岩在区内广泛发育,石英细脉充填其中,具有非常明显的挤压片理化特征,该矿与该韧性剪切带存在非常紧密的联系,是受韧-脆剪切构造控制的碎裂蚀变岩型金矿。下文结合实践对该矿地质特征进行系统研究分析,希望能为该区同类型矿床的寻找提供一定的指导意见。
The Qixia Shijia gold deposit in Shandong Province is situated in the east of Jiaobei uplift(IV), Jiaobei uplift(II) Jiaobei uplift(III) Jiaobei fault uplift(V) and adjacent to Qixia Malianzhuang uplift(V) in the south. Nearly EWtrending ductile-brittle shear zone is distributed along the contact zone between the Neoarchean Qixia sequence and the Paleoproterozoic Fanzishan Group. Mylonite is widely developed in the area and quartz veins are filled in it. It has very obvious physical and chemical characteristics of compression sheets. The ore is closely related to the ductile shear zone and is a cataclastic altered rock type gold deposit controlled by ductile-brittle shear structure. In this paper, the geological characteristics of the deposit are systematically studied and analyzed in combination with practice, hoping to provide some guidance for the exploration of the same type of deposits in this area.
