金矿产出于多种地质环境。原生金矿从斑岩型、矽卡岩型、侵入岩、火山岩中的浸染型,到变质岩、沉积岩裂隙、断裂带中的脉型、网脉型、砾岩胶结型等不下七、八类国外在寻找金矿中,采用了各种化探方法。其中,普查火山成因的金矿,以能够精确鉴定岩石类型的定量地球化学详查收效最好。在加拿大提敏斯、克克兰湖和诺兰达地区约25个不同的矿区,岩石地球化学测量表明,在金—银矿体周围由主要元素和微量元素形成了明显的蚀变晕,最常见的规模为数百米。在这个范围内,Au、As、Hg等微量元素富集,Na、Ca或Mg等主要元素富集或贫化,Si、Fe和K等元素富集。其中金作为隐伏 Gold production in a variety of geological environment. Primary gold from the porphyry type, skarn type, intrusive rock, diagenetic type of volcanic rocks to metamorphic rocks, sedimentary rock fissures, fault-type veins, reticular veins, conglomerate conglomerate no less than seven, eight In looking for gold in foreign countries, using a variety of geochemical exploration methods. Among them, the coking volcano genetic gold mine, to be able to accurately identify the type of rock quantitative geochemical detailed investigation of the best results. In about 25 different mines in the regions of Timmins, Lake Clewland and Noland, Canada, lithogeochemical measurements show that significant alteration haloes are formed around the Au-Ag orebodies by the major elements and trace elements The common size is hundreds of meters. Within this range, trace elements such as Au, As and Hg are enriched, and major elements such as Na, Ca or Mg are enriched or depleted, and elements such as Si, Fe and K are enriched. Which gold as a hidden
