广西北香铅锌锡矿区成矿地质及地球化学找矿前景评价

文章从区域成矿背景、地层、构造等几方面探讨了矿床的成矿地质条件，指出NW向同沉积断裂对矿床的空间分布、产状等起主要控制作用，其次一级NW向断裂则是矿床的主要赋存构造，矿床的形成受地层岩性和构造双重控制。通过化探次生晕异常评价，圈定出北香一下大莫和莫四一南华两个呈NW-SE走向的综合矿化异常带。认为北香一下大莫异常带的走向延伸部位以及莫四一南华异常带的深部应具有一定的找矿潜力。

Metallogenic geology and geochemical prospecting perspective evaluation of Pb, Zn, Sn polymetallic ore area in Beixiang,Guangxi

It has discussed the metallogenic geological conditions of the ore area from regional metallogenic background, strata, structure and other aspects, and pointed out that the spacial distribution and occurrence of the deposit are mainly controlled by the NW trending codepositing fracture, while the secondary NW trending fracture is the major hosting structure, and the formation of the deposit is double controlled by stra- ta, lithology and structure. Through evaluating geochemical prospecting secondary haloes＇ anomalies, it has delimitated two NW-SE trending comprehensive geochemical prospecting anomalies belts Beixiang-Xiadamo Belt and Mosi-Nanhua Belt. It has believed that there is potential for prospecting in extending part a- long trend of the Beixiang-Xiadamo anomalies belt and the deep part of Mosi-Nanhua anomalies belt.
