1961年至1962年冬,美国加利福尼亚州索尔顿湖(Salton Sea)附近勘探地热的钻井,在五千多英尺深处打到了富含重金属的高温浓卤水。随后,在1962年夏季试井的三个月里,沉积了大量井垢,经检查其中富含铜、银及其他金属。D.E.怀特等人(1963)首先注意到这种卤水可能是人类第一次得到的正在“活动”的成矿热水溶液。一热卤水两口钻井热卤水的物理化学性质见表1。卤水的温度在井口为220°±30℃,在井下推算达300～350℃。溶解物质总量在258‰以上,属于Na—K—Ca氯化物型卤水。以硫酸离子和硫化物离子形式存在的硫都很少。索尔顿湖热卤水的化学成分见表1。
From 1961 to the winter of 1962, geothermal drilling near Salton Sea, California, hit a heavy metal-rich, high-temperature brine at more than 5,000 feet. Subsequently, during the three months of the summer well testing in 1962, a large amount of scale was deposited and examined for copper, silver and other metals. D.E. White et al. (1963) first noticed that this brine might be the first “hot” solution to mineralization that was obtained by humans. A hot brine two hot brine physical and chemical properties shown in Table 1. The temperature of the brine is 220 ° ± 30 ° C at the wellhead and 300 ~ 350 ° C in the well. The total amount of dissolved substances in more than 258 ‰, belonging to Na-K-Ca chloride brine. There is very little sulfur present in the form of sulfate ions and sulfide ions. Salton Lake hot brine chemical composition shown in Table 1.
