Abstract This paper continues a series of our earlier publications summarizing literature data on the physicochemical parameters and chemical composition of fluids at endogenic gold deposits and presents estimated average values of the temperature, pressure, and salinity of fluids, and variations in these parameters, at Mesozoic gold deposits. Parameters of mineralizing fluids at the Mesozoic deposits are discussed in comparison with the analogous parameters of fluids at Archean, Proterozoic, and Paleozoic gold deposits. The Mesozoic deposits are determined to generally differ from the older deposits in having fluids of higher temperature and lower pressure, with carbon dioxide in these fluids dominating over other gases.

中生代金矿床流体物化参数及地球化学特征

摘要 本文延续了我们之前发表的一系列文章,总结了有关内生金矿床流体物理化学参数和化学成分的文献数据,并介绍了中生代流体温度、压力和盐度的估计平均值以及这些参数的变化。金矿床。中生代矿床的矿化流体参数与太古宙、元古代和古生代金矿床的流体类似参数进行了比较。确定中生代沉积物通常与较旧的沉积物不同,因为它们具有较高温度和较低压力的流体,这些流体中的二氧化碳比其他气体占主导地位。
