当解决一系列含磷岩层中金的工业矿化产出问题时,必需要综合研究矿物以及矿物的结晶条件。对于所研究区域的同类矿床的不同成矿阶段,其特征是均有铁镁质碳酸盐,而这些铁镁质碳酸盐是成矿过程的一种指示矿物。 南维尔霍扬的一个金矿床,产在维尔霍扬杂岩的含有较高有机质的陆源沉积物中,并且生成于一个深层区域断裂带中。矿床分几个阶段形成:石英-绢云母交代岩阶段;石英-白钨矿-碳酸盐阶段;石英-金硫化物阶段和石英-金-硫辉锑矿阶段。自然金主要与石英-金硫化物阶段的金属矿物组合相联系,这一阶段以强烈的碳酸盐生成过程为其
When addressing the problem of industrial mineralization of gold in a series of phosphorus-bearing formations, it is necessary to comprehensively study the crystallization conditions of minerals and minerals. For the different mineralization stages of the same deposit in the studied area, all of them are characterized by ferri-magnesian carbonate, and these maficarbonates are an indicative mineral of the ore-forming process. A gold deposit in Southwell Hoyan is produced in the terrigenous sediments of the Willow Young Complex containing higher organic matter and formed in a deep regional fault zone. The deposit is formed in several stages: quartz-sericite metasomatic stage, quartz-scheelite-carbonate stage, quartz-gold sulphide stage and quartz-gold-sulphide antimony ore stage. Natural gold is mainly associated with the metal-mineral assemblage of the quartz-gold sulphide phase, which was characterized by a strong carbonate formation
