西太平洋中大多数已知的高温热液喷发都出现在洋内弧后环境中,如劳海盆、北斐济海盆和马里亚纳海沟。在弧前的海底火山上已经发现了热液喷发和相应的矿床,其中许多火山还在排气,并有释放到海底的岩浆挥发物的证据,但是只在水深超过1 km的最深的塌陷火山口发现了黑烟喷口、典型
Most of the known high-temperature hydrothermal eruptions in the western Pacific occur in intra-oceanic arc environments such as the Lahai Basin, the North Fiji Basin and the Mariana Trench. Hydrothermal eruptions and corresponding deposits have been found on pre-arcuate submarine volcanoes, many of which are still expelled and evidence of magma volatiles released to the sea floor, but only at the deepest subsidence volcano I found a black smoke vents, typical
