PPT-Permian Coconino Sandstone:

How did it form Research by Leonard Brand PhD Loma Linda University Introduction The Permian Coconino Sandstone in N Arizona is consistently interpreted by geologists as wind deposited eolian desert sand dunes. A14 Aquifers in sandstone and carbonate rocks are most wide-spread in the eastern half of the Nation, but also extend overlarge areas of Texas and smaller areas in Oklahoma, Arkan-sas, Montana, Wyomin “One . of the largest wind-deposited formations in the geologic . record.".
