Stratigraphy
| Geological group: | Tremp | Formation: | Conques | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: in the "Lower Red Garumnian" strata
The Conques Formation is equivalent to the "lower Red Garumen" facies. The Conques Formation was previously assigned a late maastrichtian age (Sellés and Villa 2015; Villa et al. 2015) Biostratigraphy and Sr stable isotope geochemistry suggest that the La Posa and Conques Formation are entirely early Maastrichtian, lying within chron C31r (see Caus et al. 2016; Oms et al. 2016; Fondevilla et al. 2016; Fondevilla et al. 2019). | |||||
Lithology and environment
| Primary lithology: | paleosol/pedogenic,concretionary,oncoidal calcareous sandstone |
| Lithology description: "mainly composed of lutites, but with calcareous nodules in well-developed paleosols. Channel-like sandstone beds...that occasionally display oncolites at their bases, are interspersed among the lutites." | |
