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. ; 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
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
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
Cubas, C.R. ; Hernán , F. ; Ancochea Soto, Eumenio ; Huertas Coronel, María José | Sociedad Geológica de España | 1994-12Lower Old Basaltic Series had only been described W of the Basal Complex in Alojera-Tazo area but it is also well exposed in other zones on Gomera as in Hermigua area E of the Basal Complex. Here, the basaltic lava flows alternate with poligenet[...]texto impreso
Ancochea Soto, Eumenio ; Brändle, J.L. ; Huertas Coronel, María José ; Cubas, C.R. ; Hernán, F. | Elsevier Science Publishers | 2003-02-01On the northern part of La Gomera there exists a great abundance of trachytic–phonolitic dikes showing a broad diversity in dip and strike. Several methods have been applied in order to separate these dikes in different sets, localise the area f[...]texto impreso
Ancochea Soto, Eumenio ; Brändle, J.L. ; Cubas, C.R. ; Hernán, F. ; Huertas Coronel, María José | Elsevier Science Publishers | 1996-03Fuerteventura has been since early stages of its growth the result of three different adjacent large volcanic complexes: Southern, Central and Northern. The definition of these volcanic complexes and their respective growing episodes is based on[...]
