Cratonic sequence
Paleoproterozoic to Mesoproterozoic cratonic basins in the São Francisco Craton are classified into three megasequences: Statherian, Calymmian-early Ectasian, and Stenian-early Tonian sequences. The location, depositional age, and provenance of these sequences are reflected in their detrital zircon U-Pb age distributions.GEOL 106 - test 3 (ch 20) what is the epeiric sea? a) Open, deep ocean, where black shales are deposited. b) The continental platform of the continent, covered by the ocean. c) Shallow seas covering part of the craton. d) Part of the shallow proximal ocean, where reefs form.
