Juan Tavera
Juan Tavera (1917–1991) was a Chilean people, Chilean geologist and paleontology, paleontologist. His most important work was on the marine invertebrate fossils of the formations of Algarrobo Formation, Algarrobo, Arauco Formation, Arauco and Navidad Formation, Navidad. Tavera's work contributed to an increased understanding of the stratigraphy of Chile, for example by defining Ranquil Formation in 1942. Along with Charles Darwin, Juan Brüggen and Gustav Steinmann he is one of the prominent geologists to have studied Navidad Formation in Central Chile. The species ''Megatrigoniidae, Paulckella taverai'' is named after him.

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Megatrigoniidae
'' Megatrigoniidae '' is an extinct family of fossil saltwater clams, marine bivalve molluscs in the subclass Palaeoheterodonta. This family of bivalves is known in the fossil record from the Jurassic period, Tithonian age, to the Cretaceous period, Maastrichtian age. Species in this family were facultatively mobile infaunal suspension feeders.

Andean Geology
''Andean Geology'' (formerly ''Revista Geológica de Chile'') is a peer-reviewed scientific journal published three times per year by the National Geology and Mining Service, Chile's geology and mining agency. The journal covers the field of geology and related earth sciences, primarily on issues that are relevant to South America, Central America, and Antarctica with a particular focus on the Andes. The journal was established in 1974 and articles are published in English and Spanish. The editor-in-chief An editor-in-chief (EIC), also known as lead editor or chief editor, is a publication's editorial leader who has final responsibility for its operations and policies.

Central Chile
Central Chile (''Zona central'') is one of the five natural regions into which CORFO divided continental Chile in 1950. It is home to a majority of the Chilean population and includes the three largest metropolitan areas—Santiago, Valparaíso, and Concepción. It extends from 32° south latitude to 37° south latitude. Geography Central Chile is one of the five main geographical zones in which Chile is divided. The Chilean Central Valley lies between the coastal range ("Cordillera de la Costa") and the Andes Mountains. To the north is the semi-desert region known as El Norte Chico, (the "little north"), which lies between 28° and 32° south latitude. To the south lies the cooler and wetter Valdivian temperate rain forests ecoregion, in Los Lagos Region; (the latter includes most of South America's temperate rain forests). The Central valley is a fertile region and the agricultural heartland of Chile. Climate The climate is of the temperate Mediterranean type, with t ...

Gustav Steinmann
Johann Heinrich Conrad Gottfried Gustav Steinmann (9 April 1856 – 7 October 1929) was a German geologist and paleontologist. He performed various studies in the Ural Mountains, North America, South America, the Caucasus and the Alps. Steinmann had a large number of scientific publications. He made contributions to the Theory of Evolution and to the study of the structural geology and orogeny of the Andes. In the Alps and Apennines Steinmann defined what later became known as "Steinmann's Trinity," the occurrence of serpentine, pillow lava, and chert. The recognition of Steinmann's Trinity served years later to build up the theory around seafloor spreading and plate tectonics. Steinmann himself interpreted ophiolites (the Trinity) using the geosyncline concept. His studies of ophiolites in the Apennines paved the way for the discovery of allochthonous nappes in the Alps and Apennines. South America Steinmann redefined the Navidad Formation in 1895, then called Pis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juan Brüggen
Johannes Brüggen Messtorff better known by his hispanized name Juan Brüggen (Lübeck, Germany, April 25, 1887 – March 7, 1953, Santiago de Chile) was a German-Chilean geologist. One of his most famous works is the extensive treaty of ''Fundamentos de la geología de Chile'' published in 1950. Brüggen Glacier in the Southern Patagonian Ice Field is named after him. Two of Brüggen's students established the geology degree at the University of Chile; Jorge Muñoz Cristi and Héctor Flores Williams.

Ranquil Formation
The Ranquil Formation ( es, Formación Ranquil) is a Miocene and Pliocene sedimentary formation located in Arauco Province in south–central Chile, including outcrops in Mocha Island. The formation has its greatest thicknesses in the south-west, where its sediments were largely deposited in marine conditions. It overlies unconformably sedimentary formations of the Paleocene-Eocene Lebu Group. The formation is part of the fill of Arauco Basin which is a sedimentary basin that extends south of Concepción. Macrofossils of the formation are similar to those of Navidad ( 34° S) and Lacui Formations ( 43° S), two nearby Miocene marine formations. The base of the Ranquil Formation is the so-called "main unconformity", which is thought to have been formed by erosion during a period of tectonic inversion. The formation was first defined in 1942 by Juan Tavera. Units The formation has been subdivided into five units, with the lowermost being made up of sandstone and shale, and ...
