Period:
Permian, Carboniferous
Age Interval:
Moscovian – Kungurian, Sa1
Province:
Saudi Arabia
Type Locality and Naming
Column: Saudi Arabia Outcrop
Synonym: Juwayl Member of the Wajid Sandstone
Lithology and Thickness
Mainly relatively poorly cemented sandstone of variable coarseness, at certain levels conglomeratic, with interbedded varicolored sandy shales, and, thin, black to brown, ironstone bearing horizons. In some areas two horizons near the middle include granitic and metamorphic rock erratics reaching 2 meters in diameter. Locally a few thin, irregular, pale gray and pastel, dense, dolomite lenses are present, particularly in the upper part.
Lithology Pattern:
Coarse-grained sandstone
Relationships and Distribution
