桂西北是著名的滇黔桂金三角区之一部分，分布有金牙、高龙、明山等中－大型微细浸染型金矿床。近年来，该区又发现了一类新的微细浸染型金矿床——即产于辉绿岩与地层内外接触带中的金矿床。通过对该类矿床的典型代表世加金矿进行地质地球化学的初步研究，认为该类矿床为典型的浅成低温热液矿床，与区内产于中三叠统地层中典型的微细浸染型金矿床在成因上有内在的联系。
Northwestern Guangxi is a well-known part of the Yunnan, Guizhou and Guangxi Golden Triangle areas. There are medium-large fine disseminated gold deposits such as Jinya, Gaolong and Mingshan. In recent years, a new class of finely disseminated gold deposits have been discovered in the area - the gold deposits that originated in the diabase and the internal and external contact zones of the strata. Based on the preliminary study of geo-geochemistry of this type of deposit, the typical representative of the Shiga gold deposit, this kind of deposit is considered to be a typical epithermal deposit, which is similar to the typical fine disseminated in the Middle Triassic strata Gold deposits are intrinsically linked in genesis.
