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. ; 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
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[...]texto impreso
Ancochea Soto, Eumenio ; Brändle, J.L. ; Huertas Coronel, María José ; Hernán, F. ; Herrera, R. | Elsevier Science Publishers | 2008-06-10The detailed study of the age and distribution of the basic dikes of La Gomera (Canary Islands) has allowed us to reconstruct the evolution of its main volcanic edifice. The dikes of the oldest unit (the Basal Complex) have a N70°–80° dominant d[...]texto impreso
Brändle, J.L. ; Cubas, C.R. ; Huertas Coronel, María José ; Hernán, F. ; Ancochea Soto, Eumenio | Sociedad Geológica de España | 2001-10Several trachytic and phanalitic, radial and canical dyke-swarms crap out an the La Gomera narthern regian. The first age data abtained situate the intrusian episades coinciding in time with the extrusian af the Old Basalts. The earlier dykes sh[...]texto impreso
Cubas, C.R. ; Ancochea Soto, Eumenio ; Hernán, F. ; Huertas Coronel, María José ; Brändle, J.L. | Sociedad Geológica de España | 2002-11The new radiometric data from felsic domes on La Gomera allow to separate two different felsic both intrusive and extrusive episodes on the island. The early one, upper Miocene in age, includes the domes on the eastern sector of the island as we[...]texto impreso
Huertas Coronel, María José ; Hernán, F. ; Ancochea Soto, Eumenio ; Brändle, J.L. | Sociedad Geológica de España | 2006-07A more than 1000m thick pile of basaltic lava flows and pyroclasts dipping seawards rises on the western sector of San Vicente. Several systems of dikes cut across the succession that is composed of two different sequences. The lower sequence (L[...]texto impreso
Cubas, C.R. ; Hernán, F. ; Ancochea Soto, Eumenio ; Brändle, J.L. | 1992-05The Jandia is one of the three main edifices identified in the Old Basaltic Series of Fuerteventura. It shows now a semicircular shape with a nortwards facing opening. This large volcano built up by lava flows and pyroclastics corresponding to t[...]texto impreso
Anguita, Francisco ; Hernán, F. | Asociación Española para la Enseñanza de las Ciencias de la Tierra | 1999Revisamos las ideas modernas sobre el origen del archipiélago canario como base para proponer una hipótesis sintética que se apoya especialmente en datos geofísicos y de geología regional. Este nuevo modelo toma elementos de los anteriores pero [...]texto impreso
A new model, partially based on the three most widely cited previous hypotheses, Is proposed to explain the genesis of the Canary Islands. From the hotspot hypothesis it retains the notion that the islands originated from a thermal anomaly in th[...]texto impreso
Ancochea Soto, Eumenio ; Brändle, J.L. ; Hernán, F. ; Huertas Coronel, María José | Sociedad Geológica de España | 2006-01The morphological, structural and volcanological aspects of Branco, an island of the Cape Verde Archipelago, are described and interpreted in this work. The isle consists of a 700 m thick pile of basalt lava flows and scarce pyroclastics crossed[...]texto impreso
Hernán, F. ; Cubas, C.R. ; Huertas Coronel, María José ; Brändle, J.L. ; Ancochea Soto, Eumenio | Sociedad Geológica de España | 2000-05A mainly phonolitic, 10 km in diameter, cone-sheet complex crops out on the northern area of La Gomera. The swarm intrudes into the Basal Complex, The Old BasaIts and other rocks of the Trachytic-phonolitic Complex to which they belong. The cone[...]texto impreso
Ancochea Soto, Eumenio ; Hernán, F. ; Huertas Coronel, María José ; Brändle, J.L. ; Herrera, R. | Elsevier Science Publishers | 2006-10-01A review of the general volcano-stratigraphy and geochronology of La Gomera, one of the lesser known Canary Islands, has led to the establishment of a new evolutionary model. The oldest edifice corresponds to the submarine stage built up between[...]
