Rodríguez Aranda, Juan Pablo ; Sanz Montero, M. Esther ; Cabestrero, Óscar | Sociedad Geológica de España. | 2016La comprensión del método científico por los estudiantes y la población en general es más fácil si se ilustran sus diferentes fases con ejemplos concretos. El presente trabajo muestra la metodología que se ha seguido para explicar un proceso geo[...]texto impreso
Aziz, Hayfaa Abdul ; Hilgen, Frederik J. ; Krijgsman, Wout ; Sanz Montero, M. Esther ; Calvo Sorando, José Pedro | Elsevier Science B.V., Amsterdam | 2000A high-resolution cyclostratigraphic and magnetostratigraphic study was carried out on cyclically bedded successions of middle Miocene lacustrine to distal alluvial fan-floodplain deposits from the Calatayud basin, in northeast Spain. Eight (par[...]texto impreso
García del Cura, M. Ángeles ; Sanz Montero, M. Esther ; De los Rios, Mª Asunción ; Ascaso Ciria, Carmen | Sociedad Geológica de España | 2012El estudio de travertinos actuales en Alicún (Almería), con facies tobáceas asociadas, ha permitido observar la relación de facies laminares travertínicas (costras) con biofilms. Mediante óptica y electrónica de barrido sobre muestras fijadas co[...]texto impreso
Sanz Montero, M. Esther ; Rodríguez Aranda, Juan Pablo ; García del Cura, M. Ángeles | Elsevier | 2009This paper provides an ancient analogue for biologically mediated celestite and barite formation in dolomite precipitating microbial mats developed in lacustrine environments during the Miocene. Barite and celestite occurrences were studied in t[...]texto impreso
Seasonal desiccation of Mg2+–(Na+)–(Ca2+)–SO42?–(Cl?) saline lakes in La Mancha (Central Spain) that host microbial mats led to the precipitation of hydrated Na-Mg sulphates and gypsum. Sulphates precipitated in the submerged conditions form ext[...]texto impreso
Sanz Montero, M. Esther ; Rodríguez Aranda, Juan Pablo ; García del Cura, M. Ángeles ; Calvo Sorando, José Pedro | Sociedad Geológica de España. | 2012La presencia de seres vivos en los ambientes lacustres salinos se puede deducir por las estructuras de bioturbación que realizan en el sedimento. En las lagunas salinas manchegas de Lillo (Toledo) se ha distinguido un cortejo variado de dichas e[...]texto impreso
This paper gives new insight into the precipitation sequences in six playa basins that host microbial mats. The study basins are distributed across two evaporitic endorheic drainage systems located in the Central part of Spain with markedly diff[...]texto impreso
Alonso-Zarza, Ana María ; Sanz Montero, M. Esther ; Calvo Sorando, José Pedro ; Estévez López, Pilar | Elsevier | 1998Calcified root cells, forming microspar and pseudospar mosaics of calcite and/or dolomite crystals, constitute a major component of calcretes and dolocretes from the Miocene of the Madrid Basin. The calcified cells occur in massive nodules or fi[...]texto impreso
Avendaño Salas, Cándido ; Cobo Rayán, Rafael ; Sanz Montero, M. Esther ; Gomez Montaña, José Luis | ICOLD | 1997-07This paper presents updated capacity data for 101 reservoirs in nine Spanish river basins. The data were obtained by• applying two complementary procedures, photogrammetry and bathymetry. Capacity loss for the reservoirs studied is specified in [...]texto impreso

Rodríguez Aranda, Juan Pablo ; Sanz Montero, M. Esther ; Calvo Sorando, José Pedro | Sociedad Geológica de España. | 2004Microbial endoevaporite comunities thrivied in a Miocene saline lake where gypsum crystals were precipitate. As a result of both the survival strategies and the metabolic activities carried out by those communities, the gypsum crystals embedding[...]texto impreso
Wright, V.P. ; Alonso-Zarza, Ana María ; Sanz Montero, M. Esther ; Calvo Sorando, José Pedro | Elsevier | 1997Mud-grade lacustrine limestones of Miocene age from the Madrid Basin, Spain, reveal varied and complex diagenetic histories. Microporous micrites occur as well as micrites with anhedral mosaics. The micrites have recrystallized from a metastable[...]texto impreso
This paper deals with the geological and geochemical characterization of ironstone deposits encountered in two different sedimentary successions (upper Cretaceous and lower Cenozoic) in northern Bahariya, Egypt. The ironstones occur as uneconomi[...]texto impreso

Sanz Montero, M. Esther ; Rodríguez Aranda, Juan Pablo ; Calvo Sorando, José Pedro | Sociedad Geológica de España. | 2003The study focuses on dolomite carbonates that occur in a Miocene evaporitic succession, the Christmas tree gypsum unit. This unit outcrops in the eastern part of the Madrid Basin and it was deposited in a mudflatsaline lake complex during the Lo[...]
