广西北香银多金属矿床成矿地质条件与找矿潜力分析

文章从区域成矿背景、地层、构造等几方面探讨了矿床的地质特征和成矿地质条件，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。通过与丹池矿带中的类似典型矿床的对比，指出北香矿床具有与大厂长坡矿床和大福楼矿床相似的成矿条件，泥盆系地层与NW向同沉积断裂共同控矿，矿体空间产出模式应都具有“上脉下层”的特点；结合已完成的地、物、化、遥等工作成果，认为在矿床的中深部有寻找似层状矿体的巨大潜力。

Metallogenic geological conditions and prospecting potential evaluation of Ag polymetallic deposit in Beixiang,Guangxi

It has discussed the geological characteristics and ore-forming geological conditions of the deposit from regional metallogenic background, strata, structure and other aspects, and pointed out that the spacial distribution and occurrence of deposits are mainly controlled by the NW trending codepositing fracture, while the secondary NW trending fracture is the major hosting structure, and the formation of deposit is double controlled by strata, lithology and structure. Comparing with typical deposits in the Danchi mineralization belt, it has concluded that the Beixiang deposit is similar to the Changpo deposit and Dafulou deposit in Dachang because of the similar metallogenic conditions, and the Devonian strata with NW trending codepositing fracture controlled ore forming together, and the spacial occurring modes of orebodies all present the feature of upper veins and lower strata. Considering the work fruit we have gained in geology, geophysical prospecting, geochemical prospecing and remote sensing, a great potential of prospecting for stratiform-like orebodies in middle and deep part of the deposit has been indicated.
