自从大洋中脊的热水喷口发现以来,人们一直想获得深部喷口的热液的高温压时的pH、H2、H2S含量等化学参数。由高温高压下海底玄武岩的热水喷口向外2米内存在一个大的温度梯度,在海底喷口2200米(或更深)由408℃迅速减低为2℃左右。喷口外迅速堆积铁铜硫化物、铅锌硫化物,然后再外 Since the discovery of the hot water vents in the mid-ocean ridge, people have always wanted to obtain the chemical parameters such as pH, H2, H2S content at the high temperature of hydrothermal fluids in deep vents. There is a large temperature gradient within 2 meters outward from the hot water spout of the seabed basalts at high temperature and pressure and rapidly decreases from 408 ° C to about 2 ° C at the depth of 2200 meters (or deeper) at the seabed. Rapid deposition of iron copper sulfide outside the spout, lead and zinc sulfide, and then outside
