不久前,在加拉巴哥斯裂谷、东太平洋海隆、加利福尼亚湾、俄勒冈外海区等处均发现了地热带,引起了地球科学、生物学、工程学等学科研究者们的极大关注。 1977年Corliss等人乘“阿尔文”号深潜器在加拉巴哥斯裂谷(西经86°)深约2.5公里的海底,分别从4个地方直接采到17℃的热水溶液(周围的水温约2℃)。对它们进行化学分析表明:水温愈高,Li、K、Rb、Ca、Ba、SiO_2含量就愈高,而Mg、SO_4则愈低。其中,SiO_2浓度与水温有较好的线性关系。据推测,水温高达300℃、压力为1000个大气压时,SiO_2浓度可达饱和状态。
Not long ago, the discovery of the geothermal zone in the Galapagos Rift, the East Pacific Seale, the Gulf of California, the Oregon Outer Sea region caught the great attention of researchers in geosciences, biology and engineering. In 1977, Corliss and others aboard the “Alvin” deep submarine seabed in the Galapagos Rift Valley (86 ° longitude) at a depth of about 2.5 km. From each of the four places, the hot water solution (ambient Water temperature about 2 ℃). The chemical analysis of them shows that the higher the water temperature is, the higher the contents of Li, K, Rb, Ca, Ba and SiO 2 are, while the lower is Mg and SO 4. Among them, the SiO 2 concentration and water temperature have a good linear relationship. It is speculated that the water temperature up to 300 ℃, pressure of 1000 atmospheres, the concentration of SiO_2 up to saturation.
