During the early Archaean, the Earth was too hot to sustain rigid lithospheric plates subject to Wilson Cycle-style plate tectonics. Yet by that time, up to 50% of the present-day continental crust was generated. Preserved continental fragments from the
How old is the oldest oceanic crust? What is a geologic formation? Where have fossils been found from the Cretaceous Period? How many eons are represented on the geologic time scale? How are geologic epochs and eras defined? What is a geologic structure?
(1) the naked-cell theory suggesting ancestral diatoms did not have a siliceous cell covering and were not preserved (Round and Crawford, 1981), (2) a paucity of Jurassic and older marine deposits due to ocean crust subduction (Harwood and Gersonde, 1990), and (3) early diatoms might ...
