Alonso-Zarza, Ana María ; Bustamante, Leticia ; Huerta, Pedro ; Rodríguez Berriguete, Álvaro ; Huertas Coronel, María José | Elsevier | 2016-05This paper studies the weathering and soil formation processes operating on detrital sediments containing alkaline volcanic rock fragments of the Mirador del Río dolocrete profile. The profile consists of a lower horizon of removilised weathered[...]texto impreso
This work studies a fossil system of perched and fluvial travertines passing distally to fluvial tufas within a volcanic ravine. Sedimentology, petrology and geochemistry of fossil aragonitic-calcitic travertines and downstream calcitic tufas fr[...]texto impreso
Rodríguez Berriguete, Álvaro ; Alonso-Zarza, Ana María ; Martín García, Rebeca | Elsevier | 2017-05-12Diagenesis of Miocene-Pliocene continental rocks in extensional Teruel Basin related to deposition of a travertine at surface has been studied. Most of the diagenetic processes described here are in relation tothe travertine deposition, so they [...]texto impreso
The diagenesis of travertine and tufa is rarely considered an issue due to the common difficulty of distinguishing what is primary from secondary, as in most of cases these diagenetic changes occur very early. The main diagenetic features of tra[...]texto impreso
Martín García, Rebeca ; Alonso-Zarza, Ana María ; Frisia, Silvia ; Rodríguez Berriguete, Álvaro ; Drysdale, Russell ; Hellstromf, John | Elsevier | 2019-04-01Aragonite speleothems are increasingly being used as high-resolution climate proxies; however, aragonite is unstable and susceptible to diagenetic transformation into calcite leading to mineralogical, textural and geochemical alterations that ha[...]texto impreso
Huerta, Pedro ; Martín Pérez, Andrea ; Martín García, Rebeca ; Rodríguez Berriguete, Álvaro ; La Iglesia, Á. ; Alonso-Zarza, Ana María | Elsevier | 2019-04-01Lava tubes from Lanzarote Island in the Canary Archipelago commonly show white speleothems that stand out from the black basaltic rock. Mineralogical analyses of the speleothems from El Covón and Chifletera lava tubes show that gypsum is the dom[...]texto impreso
Alonso-Zarza, Ana María ; Cabaleri, Nora G. ; Huerta, Pedro ; Armella, Claudia ; Rodríguez Berriguete, Álvaro ; Monferran, Mateo D. ; Gallego, Oscar F. ; Ubaldon, María Cecilia ; Silva Nieto, Diego | Elsevier | 2020-10Large carbonate microbialite build-ups are relatively uncommon in ancient fresh-water lacustrine basins as compared with those marine and saline environments. This paper discusses the formation of a large continental lacustrine deposit, the Olig[...]texto impreso
Alonso-Zarza, Ana María ; Rodríguez Berriguete, Álvaro ; Cabrera, Mª Carmen ; Meléndez Hevia, Alfonso ; Martín, L. F. | Sociedad Geológica de España | 2012El barranco de Calabozo, en la Isla de Gran Canaria, muestra como rasgo excepcional la presencia de un edificio tobáceo/travertínico alimentado por una tubería de un sistema de regadío. La tubería se abasteció de pozos cuyas aguas son ricas en g[...]texto impreso
Camuera, John ; Alonso-Zarza, Ana María ; Rodríguez Berriguete, Álvaro ; Rodríguez González, Alejandro | Elsevier | 2014The Berrazales carbonate spring deposit is a small outcrop constituted mainly by cascade-like geometries. Four main facies have been identified: fibrous dense macrocrystalline formed by rapid degassing under high-flow conditions; framestones of [...]texto impreso

La presente Tesis Doctoral ha tenido como objetivo la caracterización petrológica y geoquímica de los travertinos y tobas del Barranco de Azuaje (Gran Canaria), así como las implicaciones paleoambientales y paleoclimáticas de su presencia en est[...]texto impreso
Rodríguez Berriguete, Álvaro ; Alonso-Zarza, Ana María ; Martín?García, Rebeca ; Cabrera, Mª Carmen | Wiiley | 2018-02-02Geochemical variations across laminated tufas and travertines may reflect the growth style of the carbonate build?up and not just climate?related changes. This work presents the study of a carbonate deposit, formed on a ravine wall in Gran Canar[...]texto impreso
Rodríguez Berriguete, Álvaro ; Alonso-Zarza, Ana María ; Cabrera Santana, María del Carmen ; Rodríguez González, Alejandro | Elsevier | 2012The Azuaje travertines in the north of Gran Canary Island crop out in the Azuaje Gorge, which is incised into Miocene volcanic breccias of the Roque Nublo Formation. This travertine is interesting because of the scarcity of travertines in the Ca[...]texto impreso
Huerta, Pedro ; Rodríguez Berriguete, Álvaro ; Martín García, Rebeca ; Martín Pérez, Andrea ; La Iglesia Fernández, Ángel ; Alonso-Zarza, Ana María | Elsevier | 2015-01Calcretes are widely described in non-marine settings with carbonates in their catchment, or vicinity areas, but in volcanic islands without carbonates in their substrate, calcretes are not very common. In Lanzarote and Fuerteventura Canary Isla[...]texto impreso
Pinho, Rayana Rosa Estrella de ; Rodríguez Berriguete, Álvaro ; Alonso-Zarza, Ana María ; Cabrera, Mª Carmen | Sociedad Geológica de España | 2015The Temisas Carbonate Building (TCB) is situated in the Temisas ravine, at the SW part of the Gran Canaria Island. Four different facies were recognised: detrital, framestone, phytoclastic and a transition between the last two facies. The carbon[...]
