On the early history of the earth

On the early history of the earth
Geological Society of America Bulletin (1965) 76 (3): 287-306


Calculation of the evolution of terrestrial surface temperatures from atmospheric composition and the most favorable solar model indicates either that model revision is necessary or that the Earth and Sun are older than 4.5 and 5.0 b.y., respectively. Rates of weathering and erosion have increased with geologic time so the duration of geosynclinal cycles should have decreased with time. Sialic crust existed at least 4 b.y. ago. Continental origin by mantle segregation is inconsistent with the age and thermal history of the Earth. Continental origin by impact of extraterrestrial material is reconsidered.
