UNKNOWNS. ‘The Great Unconformity (GU), a global erosion surface separating Precambrian and Paleozoic rocks, represents ∼100–1000 m.y. of missing geologic time. The timing of erosion and amount of denudation leading to the formation of the GU remains largely unknown, but could provide important constraints to models of cratonic vertical movements during the supercontinent cycle, and estimates of sediment production that influenced Neoproterozoic ocean-atmosphere chemistry.” https://lnkd.in/dDNSQTU View in LinkedIn
