“…(Hauterivian to Barremian) was deposited in alluvial plain, palustrine, and lacustrine environments (Liesa et al, 2006; Meléndez et al, 2009; Navarrete et al, 2013), and consists of sandstone, mudstone and limestone facies that show rapid lateral variations with distance from the anticline crest and its faults (Liesa et al, 2006). Recently, the continental Galve Formation has been defined and recognized in the strata of the Galve sub‐basin (Aurell et al, 2016, 2019). The Galve Formation is equivalent to the basal El Castellar Formation as mapped in this study, suggesting the regional Berriasian unconformity may occur within this unit as well.…”
