Huertas Coronel, María José ; Arnaud, N. ; Ancochea Soto, Eumenio ; Cantagrel, Jean Marie ; Fúster Casas, José María | Elsevier Science Publishers | 2002-06-30Many felsic pyroclastic units of various types are exposed in different sectors of Tenerife. New 40Ar/39Ar determinations allow them to be placed more precisely in the general volcano-stratigraphic succession. According to geographic distributio[...]texto impreso
A number of samples have been dredged from the upper parts of Amanay and El Banquete Seamounts, yet volcanic materials have been collected only in Amanay. Based on the textural features and the presence or absence of kaersutite, two main types o[...]texto impreso

Ancochea Soto, Eumenio ; Brändle, J.L. ; Huertas Coronel, María José | Sociedad Geológica de España | 1995-10A mathematical method has been used to determine the alignments of effusive centers in the Recent Series of the Tenerife island. The strike of these lineations varies from one sector to another. In this way,; on the northeastern part of the isle[...]texto impreso
Brändle, J.L. ; Ancochea Soto, Eumenio ; Cubas, C.R. ; Hernán, F. | Sociedad Geológica de España | 1991-12It is proposed, a computer program to help to the interpretation of radial dykes swarms and 10- cate the possible emission zones, using the analysis of theoretical intersection of the dykes, considered as straight lines on an intersecting horizo[...]texto impreso
Ancochea Soto, Eumenio ; Brändle, J.L. ; Hernández-Pacheco, Alfredo | Seminario de Astronomía y Geodesia | 1987En un área volcánica, la distribución de los puntos de emisión refleja en gran parte las pautas estructurales regionales, que condicionan esta actividad magmática; sin embargo, a veces, resulta difícil decidir sobre el terreno, basándonos únicam[...]texto impreso
Aportación geoquímica al conocimiento de los materiales volcánicos del Cámbrico medio de Zafra-Feria
Sagredo Ruiz, Juana ; Peinado Moreno, Mercedes ; Brändle, J.L. ; Arenas Martín, Ricardo ; Ancochea Soto, Eumenio | Universidade de Aveiro, Departamento de Geociências | 1988Los materiales volcánicos intercalados en el Cámbrico medio de Ossa Morena, bien expuestos en la alineación Zafra-Feria constituyen una serie moderadamente alcalina formada por basaltos plagioclásicos de ambiente submarino somero, traquitas y ri[...]texto impreso
Carabantes Alarcón, David ; Ancochea Soto, Eumenio ; Arias Astray, Andrés ; Dupont Sfez, Samuelle ; Iglesias Recuero, Silvia ; Manjón-Cabeza Olmeda, Araceli ; Martín Martín, José Oliver ; Montero de Juan, Francisco Javier ; Romero Ruiz del Portal, Francisco ; San Andrés Moya, Margarita ; Sastre Castillo, Miguel Ángel ; Tirado Fernández, Francisco | 2018-06-30El Aprendizaje Servicio es una estrategia docente necesaria para el desarrollo de iniciativas de emprendimiento e innovación social, que partan desde la Universidad, y que se puedan incorporar en las diferentes áreas de conocimiento de la UCMtexto impreso
Ancochea Soto, Eumenio ; Hernán Reguera, Francisco ; Huertas Coronel, María José ; Brändle, J.L. | Elsevier Science Publishers | 2012A basic radial dike swarm unrelated to other basic units of Boa Vista (Cape Verde Archipelago) has been localized and characterized in the central sector of the island. According to new radiometric data three main stages in the evolution of Boa [...]texto impreso
Ancochea Soto, Eumenio ; Brändle, J.L. ; Cubas, C.R. ; Hernán, F. ; Huertas Coronel, María José | Sociedad Geológica de España | 1996-05The Southern Volcanic Complex I consists mainly of basalts with scarce felsic members. On the basis of chemical and mineralogical compositional features two groups could be considered. 80th groups are alkaline, the first normal alkaline (in the [...]texto impreso
Ancochea Soto, Eumenio ; Brändle, J.L. ; Huertas Coronel, María José ; Hernán, F. ; Cubas, C.R. | Sociedad Geológica de España | 1997-05The Central Vólcanic Complex I (CVC-I) consists maihly of mildly alkaline basalts, many of them ankaramitic. The compositional differences observed are explained by fractíonation and extraction (rates between 20% and 30%) of clinopyroxene (60%),[...]texto impreso
Hernán, F. ; Ancochea Soto, Eumenio ; Brändle, J.L. ; Cubas, C.R. | Sociedad Geológica de España | 1993-07The North Edifice is one of the three main edifices identified in the Old Basaltic Series of Fuerteventura. This edifice is formed by Lower, Intermedium and Upper Series. The oldest one crops out on the low western side of the structure where th[...]texto impreso
Ancochea Soto, Eumenio ; Brändle, J.L. ; Arenas,, R. ; Peinado, M. ; Sagredo, J. | Universidad de Aveiro | 1988Las series silúricas que afloran en el noroeste del Macizo Ibérico contienen diferentes episodios volcánicos. La distribución, petrografía y geoquímica del volcanismo han sido estudiados en los sinclinales de Cabo Ortegal, Verín y Alcañices, per[...]texto impreso
Carracedo, Juan Carlos ; Ancochea Soto, Eumenio ; Pérez Torrado, Francisco José ; Meco, Joaquín ; Hernán, Francisco ; Cubas, Carmen Rosa ; Casillas, Ramón ; Rodríguez Badiola, Eduardo ; Ahijado, Agustina | Geological Society of London | 2002The Canarian archipelago comprises seven main volcanic islands and several islets that form a chain extending for c. 500 km across the eastern Atlantic, with its eastern edge only 100 km from the NW African coast. The islands have had a very lon[...]texto impreso
Brändle, J.L. ; Hernán, F. ; Huertas Coronel, María José ; Ancochea Soto, Eumenio | Sociedad Geológica de España | 2006-07The first data about the composition of lava flows from Branco Island (Cabo Verde) are presented in this work. Most lava flows in the sequence are alkali basalts (Fo84-76 olivine, En44-36 diopside, An83-31 plagioclase) showing geochemical affini[...]
