oa Madoqua - On the origin of sheeting and laminae in granitic rocks: evidence from Antarctica, the Namib Desert and the Central Sahara
Studies of granitic rock outcrops have been carried out in the McMurdo Oasis, Antarctica, and in the Namib Desert to test hypotheses of formation of large scale sheeting structures and of laminae. Laminae were also investigated in the Central Sahara. Evidence from Antarctica strongly supports the contention that sheeting may be a secondary feature resulting from unloading: evidence from the Namib is more equivocal but offers some support for this hypothesis.
