1.2 Billion Years of Rock is Missing; The Mystery of the Great Unconformity

Summary During the Crygenian Period the earth was largely covered with thick ice. Geologists suspect that the ice sheets caused so much erosion that they swept over a billion years worth of deposited rock into the oceans. The result is the Great Unconformity where 520 million year old sandstone appears directly over 1.7 billion year old rock in places like the Grand Canyon.
