Stratigraphy
| Geological group: | Tremp | Formation: | Conques | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Uppermost lower red unit of the Tremp Formation, only 35m beneath the Vallcebre Limestones and laterally equivalent strata unit
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). | |||||
