含金硫化物建造矿床一例说明,为了查清一个矿床范围内的含金石英-硫化物矿脉和矿脉范围内的矿柱基本富集规律以及预测隐伏矿体,需综合运用构造-地球化学准则。矿床由下列岩石构成:1,早古生代变质辉长岩类岩石;2,中古生代-旱中生代脉岩-花岗岩、花岗正长岩;3,中-晚侏罗世浅成和次火山小侵入体和岩墙-斜长斑岩和霏细玢岩;4,晚侏罗-早白垩世霏细岩次火山
A case study of gold-bearing sulphide-bearing ore deposits shows that in order to find out the basic enrichment regularity of ore pillars within the gold-bearing quartz-sulfide veins and veins in a deposit area and to predict the concealed orebodies, the tectono-geochemical criteria should be synthetically applied. The deposit is composed of the following rocks: 1. Early Paleozoic metamorphic gabbro; 2. Middle Paleozoic-drab Mesozoic dykes-granite and granodiorite; 3. Little to medium Jurassic minor and subvolcanic intrusions Body and rock wall - plagioclase porphyry and fissile rock; 4, Late Jurassic - Early Cretaceous Fei fine rock sub-volcano
