一、按分布广度分类1.常见标志矿物:这类矿物有石英、黄铁矿、褐铁矿等。它们在金矿床中与金矿物密切伴生或共生,且大量出现,多与金矿有成因联系。2.多见标志矿物:这类矿物是方铅矿、黄铜矿、闪锌矿、辉铜矿、辉锑矿、毒砂、磁黄铁矿等。它们常见于矿化蚀变带、矿化带或氧化带中,多呈金属硫化物出现3.少见标志矿物:如蔷微辉石、辉铋矿、黑钨矿、白钨矿等。它们虽然在矿化蚀变带或矿化带中出现较少,但在金矿区内可能与金矿床有成因联系或具指示意义。
First, according to the breadth of the classification 1 common logo minerals: These minerals are quartz, pyrite, limonite and so on. They are closely associated with or symbiotic with gold minerals in the gold deposits, and occur in large quantities, and are more genetically linked to gold deposits. 2. More visible signs of minerals: These minerals are galena, chalcopyrite, sphalerite, chalcocite, stibnite, arsenopyrite, pyrrhotic and so on. They are common in the mineralized alteration zone, mineralization zone or oxidation zone, mostly metal sulfides appear 3. rare mark minerals: such as Qiangpianite, bismuthinite, wolframite, scheelite and so on. Although they appear less in mineralized alteration zone or mineralized zone, they may be related to or indicate the origin of gold deposits in the gold mining area.
