The Pan-African orogeny was a series of major Neoproterozoic orogenic events which related to the formation of the supercontinents Gondwana and Pannotia about 600 million years ago.[1] This orogeny is also known as the Pan-Gondwanan or Saldanian Orogeny.[2] The Pan-African orogeny and the Grenville orogeny are the largest known systems of orogenies on Earth.[3] The sum of the continental crust formed in the Pan-African orogeny and the Grenville orogeny makes the Neoproterozoic the period of Earth's history that has produced most continental crust.[3]
