E. (1931). Paleontology of the Jurassic and cretaceous of west central Argentina. In ''Memoires of the University of Washington'' (Vol. 1, pp. 1–599). This formation is the youngest one of the Mendoza Group, overlying the Mulichinco Formation, Mulichinco and Bajada Colorada Formations and overlain by the Huitrín Formation, Huitrín and La Amarga Formations. It is dated to the Valanginian, Late Valanginian to Hauterivian, Early Hauterivian,Voglino, 2017, p.39 Valanginian, Late Valanginian to Barremian, Early Barremian,Voglino, 2017, p.49 or Hauterivian to earliest Aptian.Gómez Dacal et al., 2018, p.113 The Agrio Formation is considered the third most important source rock in the hydrocarbon-rich Neuquén Basin, after the Vaca Muerta, Vaca Mu ...

Type Locality (geology)
Type locality, also called type area, is the locality where a particular rock type, stratigraphic unit or mineral species is first identified. If the stratigraphic unit in a locality is layered, it is called a stratotype, whereas the standard of reference for unlayered rocks is the type locality. The term is similar to the term type site in archaeology or the term type specimen in biology. Examples of geological type localities Rocks and minerals * Aragonite: Molina de Aragón, Guadalajara, Spain * Autunite: Autun, France * Benmoreite: Ben More (Mull), Scotland * Blairmorite: Blairmore, Alberta, Canada * Boninite: Bonin Islands, Japan * Comendite: Comende, San Pietro Island, Sardinia * Cummingtonite: Cummington, Massachusetts * Dunite: Dun Mountain, New Zealand. * Essexite: Essex County, Massachusetts, US * Fayalite: Horta, Fayal Island, Azores, Portugal * Harzburgite: Bad Harzburg, Germany * Icelandite: Thingmuli (Þingmúli), Iceland * Ijolite: Iivaara, ...
