Thank you for your link to geothermal activity in Antarctica SoSick, though it has nothing to do with hydrothermal vents (which don't appear to have anything to do with this thread anyway). Presumably you read on that link page where it says that Mt. Melbourne formed 5 million years ago, and that its youngest volcanic dome is 2 million years old? How about where it says that Antarctica fused with another crustal plate 65 million years ago and that the Antarctic plate hasn't moved much in the last 10 million years?



Please explain to me why you think that thermal vents are responsible for the seashells on top of Mt. Everest. Instead of, for example, deposition of fossils on a seabed and subsequent uplift.
