Abstract
⺠Natural fission of 235U was a significant source of heat in the earth before about 2 Ga. ⺠Fission developed depleted Archean lower crust that now has a low heat generation. ⺠The lower crust is an inaccessible depleted reservoir that accounts for the first lead isotope paradox. ⺠The earth was cool enough by 2.0-1.8 Ga that widespread networks of orogenic belts could develop. ⺠Networks of orogenic belts at 1.8 Ga partly generated the supercontinent Columbia.
