Stratigraphy
| Formation: | Saman | Member: | Saman Conglomerate | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: LITHOSTRATIGRAPHY: From the Saman Conglomerate of the Saman Fm, which regionally overlies the Restin Fm of the Parinas Gp (Middle Eocene). AGE: Late Eocene (p. 9), on the basis of molluscan biostratigraphy. Foraminifera suggest an upper Eocene age. Olsson states that the Talara and Saman rocks can be referred to the Upper Eocene and in terms of the European section, to the Bartonian and Ludian.....respectively? STRATIGRAPHIC POSITION: From unknown position within formation. | |||||
