Portezuelo Formation The Portezuelo Formation is a geologic formation outcropping in the Mendoza, Río Negro and Neuquén provinces of Argentina. It is the fourth-oldest formation in the Neuquén Group and the older of the two formations in the Río Neuquén Subgroup. Formerly, that subgroup was treated as a formation, and the Portezuelo Formation was known as the Portezuelo Member.

Ojo Alamo Formation The Ojo Alamo Formation is a geologic formation spanning the Mesozoic/Cenozoic boundary. Dinosaur remains are among the fossils that have been recovered from the formation, though all dinosaur remains come from the lowest part of the formation, the Naashoibito member (sometimes considered part of the Kirtland Formation, which dates to the late Maastrichtian stage of the Cretaceous period.

Eastern Andes Metamorphic Complex The Eastern Andes Metamorphic Complex is a large coherent but varied group of metamorphic and sedimentary rocks –in other words a geologic complex– that crops out in the eastern Patagonian Andes in Chile and Argentina. The metamorphic grade of rocks varies but does not exceed greenschist facies, the only exception to this are rocks near plutons affected by contact metamorphism. The sedimentary protoliths sedimented in the Late Paleozoic. The pressures and temperatures of metamorphism of the Eastern Andes Metamorphic Complex are different those usually expected from accretionary complexes. The sedimentary protoliths of the Eastern Andes Metamorphic Complex were likely deposited in a passive continental margin.

Sabana Formation The Sabana Formation (Spanish: "Formación Sabana" , Q1, QTs) is a geological formation of the Bogotá savanna, Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes. The formation consists mainly of shales with at the edges of the Bogotá savanna lignites and sandstones. The Sabana Formation dates to the Quaternary period; Middle to Late Pleistocene epoch, and has a maximum thickness of 320 m , varying greatly across the savanna. It is the uppermost formation of the lacustrine and fluvio-glacial sediments of paleolake Humboldt, that existed at the edge of the Eastern Hills until the latest Pleistocene.

Coquimbo Formation Coquimbo Formation (Spanish: "Formación Coquimbo" ) is a Miocene and Pliocene sedimentary formation located in Coquimbo Region in Norte Chico, Chile. In the area of Tongoy the Coquimbo Formation was deposited in an ancient bay that was formed in a graben or half-graben, with a normal fault dipping east. Sea level changes during the Holocene have caused erosion to cut several marine terraces into the formation.

Cheuquemó Formation Cheuquemó Formation (Spanish: "Formación Cheuquemó" ) is a geological formation of sedimentary rock in south-central Chile. The sediments of the formation were deposited during the Late Oligocene and Early Miocene epochs. The formations lower sections are made up of conglomerate, then successions of sandstone, tuff and mudstone rich in organic material follows. The formation indicates that sedimentation occurred in a estuarine (paralic) and other non-marine (continental) environments. It contains fossils of the following genera: "Mytilus", "Cardium" and "Turritella". Stratigraphically it overlies the Bahía Mansa Metamorphic Complex and underlies the Miocene Santo Domingo Formation.

Estratos de Pupunahue Estratos de Pupunahue is the name given to the sedimentary strata of Oligocene-Miocene age that crop out in Pupunahue and Mulpún near Valdivia, Chile. Outside this locality Estratos de Pupunahue extends below the surface over a larger area. The thickness of the strata varies from a few meters to 530 meters. The strata were initially described by Henning Illies.
