Khashm Formation, A New Lithostratigraphic Unit Within The Cretaceous Wasia Group Of Arabia

Abstract

The Khashm Formation is introduced as a new lithostratigraphic unit to include the sandstones and shale interbeds which constitute the upper part of the Cretaceous Wasia Group (s. /.) outcropping in central Arabia. It replaces the name ;Wasia Formation (s. s.) of authors which does not conform with the rules of the stratigraphic nomenclature. The Khashm Sandstone is equated with the Wara, Ahmadi and Magwa Formations (Cenomanian, Turonian) in the subsurface of eastern Arabia.
