The Genesis Rock is a sample of original lunar crust from around the time the Moon was formed. It was retrieved from the Moon by Apollo 15 astronauts James Irwin and David Scott.
Chemical analysis of the Genesis Rock indicates that the rock is an anorthosite, composed mostly of the plagioclase feldspar, anorthite. The rock was formed in the early stages of the solar system, at least 4 billion years ago.[1] It was recovered in a crater of the Moon, near other rocks of its kind.
