Genesis: early life survived in the Polar Circles by precipitating banded iron formation (~ 3.7–1.85 Ga) followed by stratified ferruginous siliciclasts until ~ 580 Ma, when tectonically shifted to lower latitudes initiating the ‘Cambrian Explosion’
The inclination of Planet Earth’s axis of rotation by 23½° resulted in extreme climatic changes. Weak, solar radiation upon the Polar Circles during...
