Stratigraphy
Formation: | Castilletes | ||||
Stratigraphic resolution: | formation | ||||
Stratigraphy comments: This collection had an E. Miocene age assigned, but 16Ma can more specifically be assigned to the Burdighalian. |
Lithology and environment
Primary lithology: | massive,gray lithified mudstone | ||
Secondary lithology: | massive,gray lithified sandy mudstone | ||
Lithology description: The formation is composed of grey massive mudstone, fossiliferous mudstone and siltstone, fossiliferous wackestone to packstone, and medium-grained to conglomeratic fossiliferous lithic to quartz sandstone. Thick successions of mudstone (~50 m) dominate the unit and form long valleys. Thin beds of biosparite and sandstone (50 cm to 2 m) are interbedded and form laterally extensive ridges. Sandstone often present planar and cross-bedded stratification. Sandy and silty facies increase toward the top of the formation, forming prominent hills. Fossiliferous horizons are common within the unit, with marine invertebrate fossils occurring in a broad range of facies (calcareous, sandy, silty, and muddy sediments), whereas terrestrial vertebrates tend to be restricted to muddy sediments and are often associated with freshwater invertebrate fossils. Sandy facies toward the top of the formation are also rich in vertebrate fossils. | |||
Environment: | terrestrial indet. | Tectonic setting: | pull-apart basin |
Geology comments: The Castilletes Formation was deposited in a shallow marine (estuarine, lagoonal, and shallow subtidal) to fluvio-deltaic environment with strong fluvial influence. |
