c13.s7.2

After the erosion of the first 'recorded' mountain chains, large areas of the continents were again covered by water, and thick layers of new deposits were formed on top of the previous ones. Then another revolution (the Algonkian) ensued, accompanied by new mountain formation processes and new intrusions of granite lavas, again followed by a long quiet sedimentation period. Then again a revolution, again a period of transgressional seas and another sedimentation.
