徐州西南部班井侵入杂岩体位于徐州—宿州弧形构造带的中部,侵位于造山后的拉伸构造环境,侵位时代为早侏罗世,通过对岩体与围岩接触关系及其含矿性的分析表明,研究区岩体(脉)地表出露较好,与围岩接触关系较清楚,矿化蚀变现象较明显,其与山东平邑归来庄地区地质构造背景极其相似,是寻找“归来庄式”金矿的有望地区。 The intrusion intrusive complex in the southwestern part of Xuzhou is located in the central part of the Xuzhou-Suzhou arc-shaped structural belt and intruded in the extensional tectonic setting after orogenic activities. The emplacement age was Early Jurassic. Through the contact relationship between the rock mass and the surrounding rock and its The ore-bearing analysis shows that the surface of the rock mass (vein) is well exposed in the study area, the contact with the surrounding rock is relatively clear, and the mineralization and alteration phenomenon is obvious. The geomorphic structure is very similar to the Gulaizhuang area in Pingyi, Is looking for “return to Zhuang style gold” promising area.
