加拿大西北泰瑞特银—镍—钴—铋—砷—铀矿脉产在火山—沉积岩和大熊湖杂岩岩基侵入岩中。矿脉脉石矿物的流体包裹体资料反映了热液流体宽广的盐度和温度范围。流体的盐度范围大约为15—35wt% NaCl 当量。均一温度范围:第Ⅰ阶段为150—250℃,第Ⅱ阶段为220—480℃,第Ⅲ阶段为250—350℃,第Ⅳ阶段为150—250℃,第Ⅴ阶段为90—250℃。Ⅱ和Ⅲ阶段矿物中富液和富气包裹体共生表明了热液流体曾沸腾或泡腾。Ⅱ和Ⅲ阶段矿物饱和及 The Northwest Terreter silver-nickel-cobalt-bismuth-arsenic-uranium vein in Northwest Canada is intrusive in volcanic-sedimentary rocks and the Big Bear Lake complex intrusive rocks. Fluid inclusions of veins and minerals reflect the broad salinity and temperature range of hydrothermal fluids. The salinity of the fluid is in the range of about 15-35 wt% NaCl equivalents. The homogeneous temperature range is 150-250 ° C for stage I, 220-480 ° C for stage II, 250-350 ° C for stage III, 150-250 ° C for stage IV and 90-250 ° C for stage V. The symbiosis of rich and gas-rich inclusions in stages II and III shows that hydrothermal fluids have boiled or effused. Ⅱ and Ⅲ stage mineral saturation and
