细脉浸染型金矿属含金石英脉型金矿的一个亚类,其特征:①矿体由密集的成群、成组平行排列的石英细脉带所组成,脉带的长度几十米至几百米,宽数至数十米,延深达数百米,单脉一般小于一厘米,少数5—10厘米;②围岩具有一定的含金性,它与脉体可构成一定品位的工业矿体,若以1—2克/吨为边界品位,可圈出数米乃至数十米宽的矿化带;③含金品位的高低与含脉率的高低有密切关系;④自然金与围岩及脉体中的毒砂、黄铁矿有关。 Fine vein disseminated gold is a sub-group of gold-bearing quartz vein type gold deposits, characterized by: â ’¢ ore body consists of dense clusters, consisting of a group of quartz veinlets arranged in parallel, the length of the pulse tens of meters To a few hundred meters wide to tens of meters, the extension of several hundred meters, a single pulse is generally less than one centimeter, a few 5-10 cm; rock has a certain gold content, Of the industrial ore body, if 1-2 g / t as the boundary grade, can circle a few meters or even tens of meters wide mineralized belt; ③ the level of gold content and pulse rate is closely related to the level; ④ natural Gold and the surrounding rock and veins of arsenopyrite, pyrite related.
