广西武宣—象州地区铅锌成矿带深部找矿前景及找矿思路探讨——以盘龙矿区为例

Prospecting potential and prospecting idea of deep parts of Pb-Zn metallogenic belt in Wuxuan-Xiangzhou area of Guangxi——a case study of Panlong mining area

广西武宣―象州地区铅锌成矿带处在广西三级构造单元来宾凹陷和大瑶山隆起的结合部位,大瑶山背斜西翼。盘龙铅锌矿随着开采的深入,人们对矿床的地质特征、成矿规律、控矿因素的认识有了提高,展开就矿找矿,加强深部找矿,于2011年提交了-150m标高以下铅锌金属量120万吨,矿床规模为大型矿床。盘龙铅锌矿床深部找矿的重大突破对在武宣―象州铅锌成矿带内的老矿山及外围继续寻找铅锌矿床具有重要的推动作用。本文介绍了武宣―象州地区铅锌成矿带地质概况,结合盘龙矿区深部找矿实例,讨论了本区进行深部的找矿前景及找矿思路。

Pb-Zn metallogenic belt in Wuxuan-Xiangzhou area of Guangxi is located at the binding site of Laib-in topographic depression and Dayaoshan uplift which both are grade 3 tectonic units of Guangxi,and it is al-so situated at the west-wing of Dayaoshan anticline.As the exploration works are carried out in Panlong Pb-Zn deposit,more knowledge of geological characteristics,metallogenic regularity,ore-controlling factors is accumulated.Through making ore search nearby and conducting prospecting works in deep part,below the-150m elevation the amount of metal Pb and Zn is filed as 1.2 million tons in 201 1,and the deposit is de-fined as a large-scale deposit.The breakthrough in the prospecting works at deep parts of Panlong Pb-Zn de-posit greatly pushes forward the prospecting work in old mines in Wuxuan-Xiangzhou Pb-Zn metallogenic belt and its periphery area.This paper made a brief introduction on the geology of Wuxuan-Xiangzhou Pb-Zn metallogenic belt,and it discussed the potential and ideas of prospecting at deep parts of this area based on the deep ore prospecting project in Panlong mining area.
