Stratigraphy comments: LITHOSTRATIGRAPHY: The Savaneta Member of the Springvale Formation, which is correlated with the Melajo Clay Member of the Springvale Formation, although part of it may be older. AGE: Late Miocene in Woodring (1973, 1982). STRATIGRAPHIC POSITION: Composite list for member.
Lithology and environment
Primary lithology:glauconitic unlithified sandstone
Includes fossils?Y
Lithology description: LITHOLOGY: Glauconitic sandstone. LITHIFICATION: Unlithified, on the basis of figured specimens.
Environment:coastal indet.
Geology comments: The Melajo fauna can be divided into two assemblages: one occurring the limestone and coarse sand near the base of the Melajo Clay, the other on in the overlying clay and silty clay. The difference of the two assemblages is facies controlled. The basal assemblage represents a typical, tropical, near-shore fauna, whereas the overlying assemblage points to a deeper environment. This collection is derived from the clay assemblage, a siliciclastic and deeper water environment and is hence assigned to a siliciclastic - offshore environment.
