WebbPeridotite is distributed widely across the globe because it is the dominant rock that composes the Earth’s crust. It is a layer that lies beneath a thin layer of other sediments. As the Earth’s crust shifts it may expose the underlying peridotite layer, but this layer is very unstable when exposed.
