广西冶金地质勘探公司273队,在桂东南地区找到了一个以银为主的多金属矿床,目前获得的银储量构成了大型银矿床.同时还获得了一定数量的铜、金、铋储量.外围找矿仍在继续扩大远景. 该矿床被认为是裂隙充填成因.它位于广西“山”字型构造前弧左翼的龙山鼻状背斜倾没端之南.矿区地层呈北东向的单斜状展布.断裂构造比较发育.矿床按矿体成因及其赋存的地质条件及分布特征,可分为南北二个矿带:北矿带位于大天平山岩体南缘的凹陷部位,分布有那高岭组钙质岩石,常有钠长斑岩脉穿插;南矿带矿体产于郁江组砂岩、页岩中,明显受北东东和南北向两组断裂构造控制. 从1956～1972年,该区先后有七个单位以找铁为主,进行了普查、钻探、磁法、化探普查、详查
Guangxi Metallurgical Geological Prospecting Company 273 team found a silver-dominated polymetallic deposit in southeastern Guangxi, and the silver reserves currently obtained constitute a large silver deposit and a certain amount of reserves of copper, gold and bismuth are also obtained. The prospecting is still continuing to broaden its prospect, which is believed to be the cause of fissure filling. It is located south of the dumping site of the Longshan nose anticline on the left-hand front arc of the “Shan” -shape in Guangxi. The distribution of fractures is relatively developed.The deposit can be divided into two northern and southern ore belts according to the genesis of the ore body and its geological conditions and distribution: the northern ore belt is located in the depression of the southern margin of the Dapingping Mountain rock mass, There are calcareous rocks in the Gaoling Formation, often interbedded with albite rocks, and the ore bodies of the southern orebodies are produced in the sandstone and shale of the Yujiang Formation and obviously controlled by two sets of fault structures in the NE and NS directions. From 1956 ~ In 1972, there were seven units in the district that mainly looked for iron and conducted census, drilling, magnetic method, geochemical survey, detailed investigation
