在墨西哥西南海底的东太平洋隆起,存在着十分活跃的水下温泉。由于热液的流出,伴随有硫化物的急剧形成,进行铁锰的堆积。东太平洋隆起上,分布有许多条彼此张开的裂缝,它们平行隆起的脊部,每条裂缝的宽度从几十厘米到四米。东太平洋隆起的海底拉伸速度也很大,可达12厘米/年。大约30万年以来,平均速度是6厘 Uplift in the eastern Pacific Ocean southwest of Mexico, there is a very active underwater hot springs. Due to the outflow of hydrothermal fluids, the accumulation of iron-manganese proceeds as a result of rapid formation of sulfides. On the eastern Pacific uplift, there are many cracks spreading over each other, with parallel raised ridges, each with a width ranging from tens of centimeters to four meters. The swelling of the seabed on the eastern Pacific uplift speed is also very large, up to 12 cm / year. About 300,000 years, the average speed is 6%
