根据流体包裹体研究,获得了大西洋北纬26°区现代海底热液系统中矿物结晶条件的第一手资料。结晶温度270～340℃,溶液盐度5.7～7.0eq.mass% NaCl,CO_2浓度9.0～53.5g/kgH_2O,烃浓度7.3～18.2g/kg H_2O。未发现溶液沸腾标志。将最近获得的关于现代海洋成矿系统和大陆黄铁矿矿床(二者均发现有CO_2水溶液即液态CO_2的流体包裹体)的研究结果进行对比,并未获得将该矿床归入古海底热液矿床的足够证据。
According to the study of fluid inclusions, the first-hand information on the mineral crystallization conditions of the modern seafloor hydrothermal system in the 26 ° North Atlantic is obtained. The crystallization temperature is 270 ~ 340 ℃, the salinity of solution is 5.7 ~ 7.0eq.mass% NaCl, the concentration of CO_2 is 9.0 ~ 53.5g / kgH_2O and the hydrocarbon concentration is 7.3 ~ 18.2g / kg H_2O. No solution boiling mark found. Comparisons of the results of recent studies on modern marine mineralization systems and continental pyrite deposits (both fluid inclusions found to be CO 2 aqueous solutions, ie, liquid CO 2) have not been classified as ancient hydrothermal fluids Sufficient evidence of the deposit.
