Lacustrine deposits and oncoids at the middle section of the Remoredo Formation (Precuyano), Rio Grande Valley, Mendoza)

Lower Jurassic deposits of the middle section (19 m) of Remoredo Formation at Arroyos Montanes, Montanesito and El Yeso, and their oncoids are described. Three main facies are considered: limestones with oncoids, claystones and pyroclastics. According to layer configuration the oncoids can be assign...

Three main facies are considered: limestones with oncoids, claystones and pyroclastics. According to layer configuration the oncoids can be assigned to Type I and hybrids I3-I. The continuous micritic laminations suggest agitated conditions, and the discontinuous laminations reflect short periods of non agitation or tranquility. The oncoids are associated with a well preserved faunal assemblage of ostracods and some fragments of bivalves that are indicative of shallow water conditions. The facies are interpreted as the products of deposition in a shallow-water lake, constituting a coarsening-upward sequence and a progressive infilling by pyroclastic subaqueous flows. -from English summary Fil:Lanes, S.
