Stratigraphy
Geological group:Buntsandstein Formation:Areniscas y Lutitas del Figaro
Stratigraphic resolution:bed
Stratigraphy comments: "Buntsandstein facies from the Montseny-Llobregat Domain, included in the Areniscas y Lutitas del Figaro unit, and dated as early-to-middle Anisian (Middle Triassic)." (Fortuny et al. 2011)
"The first palynological work in this Buntsandstein facies (Solé de Porta et al. 1987) dated the unit as Anisian. A recent palaeomagnetostratigraphic study excludes the possibility of an Olenekian stage and biostratigraphic analysis of the overlying lower Muschelkalk facies indicates an age of middle-to-upper Pelsonian to upper Illyrian (middle-to-upper Anisian), on the basis of the presence of the conodonts Paragondolella bulgarica, P. hanbulogi, P. bifurcata, Neogondolella constricta, N. cornuta, N. excentrica, and N. basisymetrica. In addition, the brachiopod Spiriferina (Mentzelia) mentzeli is recognized at the base of this facies and the ammonite Paraceratites fauna is located in the middle part of the lower Muschelkalk facies. All these data restrict the La Mora site to an Aegean-to-middle Pelsonian age (early-to-middle Anisian)." (Fortuny et al. 2011)
Lithology and environment
Primary lithology: sandstone
Includes fossils?Y
Lithology description: The section is 25 m thick and is composed of intercalations of red clay, mudstone, and sandstone in four sedimentary sequences with five different facies bound by caliche-type palaeosols. The materials are interpreted as infilling of a channel body with an erosional base and a topping plane. Facies A represents the first deposits that formed the base of the level and deposits B are enclosed by the margin of the channel. Both are interpreted as point bars. In relation to these point bars, the sandstone from facies C fills the central part of the channel and its equivalent to the lower part of the deposits of the point bar. Facies C yields the vertebrate locality. The clay and silt from facies D constitute the final infilling of the abandoned fluvial channel and extend beyond the boundary of the channel as flood-plain deposits. In facies E, the sediments show a concentration of calcium carbonate nodules.
