Exploratour 09: Rock that jams


You are faced with living proof that rocks from prehistoric times determine what is alive today: the mosses you see here only grow in wet locations. The water is dammed by serpentinite. This impermeable rock was formed during the formation of the ocean 160 million years ago, when these rocks were pulled out of the Earth's crust on the seafloor from a depth of over 30 km.
