Anguita, Francisco ; Anguita, Jorge ; Castilla Cañamero, Gabriel ; Casa, Miguel Ángel de la ; Domínguez, José María ; Herrera, R. ; Llanes Estrada, Pilar ; López, Mónica ; Martínez, Vicente | Springer Science Business Media | 1997Abstract. A regional geologic study of Arabia Terra, a densely cratered area of Mars northern hemisphere, has revealed the individuality of this province. This is best expressed by an equatorial belt with a crater age distinctly younger as compa[...]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
Herrera, R. ; Huertas Coronel, María José ; Ancochea Soto, Eumenio | Sociedad Geológica de España | 2008-05This essay shows some new dating of the Basal Complex of La Gomera Island and among them, the first ones obtained using the 40Ar-39Ar methodology. Two of them are rocks of the Submarine Edifice. In the first one we obtain an age of 11,49 ± 0,66 [...]texto impreso
Herrera, R. ; Ancochea Soto, Eumenio ; Huertas Coronel, María José | Sociedad Geológica de España | 2006-01The Submarine Edifice rocks are the oldest rocks in La Gomera. This edifice is made up of submarine lava and breccias, with marine sediments associated, all of which is transverse by a very dense network of diques. This essay shows the first geo[...]texto impreso
Herrera, R. ; Ancochea Soto, Eumenio ; Huertas Coronel, María José | Sociedad Geológica de España | 2002-11The "Horizontal Basalts" in the Agulo area are made up of a more than 600m thick succession of basaltie flows that filled a SW-NE trending paleo-valley. Compositions vary between picrite and trachybasalt. The lithologic and geochemical variabili[...]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[...]texto impreso
