摘要
萨尔布拉克金矿为破碎蚀变岩型金矿，矿体严格受“菱形构造”和岩屑晶屑凝灰岩的控制．在平面上是透镜状近多间距出现，剖面上呈膝状拐折．以矿石中含有较多毒砂为特征．围岩蚀变强烈．具有明显的烛变分带性，从中心向两侧，蚀变具对称性．矿石中金含量与毒砂、黄铁矿的含量成正相关，五角十二面体黄铁矿与金矿化更为密切．
Salbulak gold deposit is that of altered rock tyoe in fracture belt, ore bodies are controlled byrhomthe fault structure, lithoclase-ctystultuffs and middle-coarse grain sandstones and occurred inlense Shape through the same distances. Ore is characterized by abundant arsenopyrite. (The wallrocks were altered Strongly, and zoned altered rocks distributed in both sides of ore fories Symmetri-cally, three zones of altered rocks are distingulshed from centte of ore thehe tO the sides, that wasquartz -arsenoPyrite - pyrite zone, Sericite - carbonate - quarts - pyrite zone and epidote - chlorite-carbonate zone' The grfor of gold ore increases with increasins of arsenopyrite and pyrite in ore,and Pen tegon al - dodecahed ron pyrite is related mo re closely with gold mineralization.
