Formation
Nubian sandstone ranges in age from the Cambrian to Upper Cretaceous eras. Positioning of the paleoequator and paleolatitude at 20° S was derived from paleomagnetic data showing Nubian sandstone was originally deposited in the paleoequatorial to subequatorial zone. These paleomagnetic results corroborated previous studies suggesting there was no polar wandering and continental drift in Africa during 210 to 110 million years and extended this period to 85 million years. Nubian sandstone is deposited under a tropical to subtropical climate and is formed under a variety of continental conditions, excluding eolian merging intermittently into shallow marine.

“... the mass migrations now habitual in our nation are disastrous to the family and to the formation of individual character.

—Kent Nerburn (20th century)
“The formation of an oppositional world view is necessary for feminist struggle. This means that the world we have most intimately known, the world in which we feel “safe” ... must be radically changed. Perhaps it is the knowledge that everyone must change, not just those we label enemies or oppressors, that has so far served to check our revolutionary impulses.”
—Bell (c. 1955)
