| Stratigraphy comments: This collection had a Montehermosan age assigned. However, the authors said: Recently, LINARES (2004), on the basis of the mammalian fauna, has assigned an age corre- sponding to the Montehermosan SALMA (late Miocene - early Pliocene) to the E1 Jebe Member of Codore Fm., and suggested a probable age of 6 Ma for the contact be- tween the Urumaco and Codore formations.
The Montehermosan max and min ages have changed so the age is now changed to Messinian-Zanclean instead. | |||||
Lithology and environment
| Primary lithology: | "cross stratification",brown sandstone |
| Includes fossils? | Y |
| Lithology description: This geologic unit is divided into two (see Liddle 1946) or three (see Rey 1990) members, according to different authors. Lithologically, it comprises a succession of ochraceous to dark brown sandstones with cross-stratification, and light-colored limolites with intercalated carbonatic levels of varying thickness. | |
| Environment: | fluvial-deltaic indet. |
| Geology comments: The depositional environment has been interpreted by Rey (1990) as characteristic of a distal fan-delta, with an alluvial plain associated with small meandering channels, and some brief intervals of marine invasion halfway through the sequence. The presence of palynomorphs allows to infer subhumid to dry climate throughout the entire deposition of the Codore Fm. | |
