Bauxitas kârsticas de la Sierra de Boada (Sierras Marginales surpirenaicas, Alös de Balaguer, Lleida)
(Sociedad Geológica de España, 1994)One of the most important bauxite site in the Spanish Pyrenees is the Sierra de Boada which is analyzed in this note. The bauxites are located between Middle Jurassic dolostones and Upper Cretaceous sandstones. They are ... -
Calizas oolíticas entre facies pelágicas en el Jurásico medio de Iznájar (Prov. de Córdoba, Subbético): significado paleogeográfico y paleobati métrico
(Sociedad Geológica de España, 2001)On the top of the Zegrí Fm (Aalenian-Bajocian) oí the Median Subbetic in the Iznajar area (south of the Córdoba province) oolitic limestones outcrop, interbedded between pelagic facies. These oolitic limestones were ... -
Cicatriz de slump en rocas pelágicas del Jurásico: su relación con el subvolcanismo (Priego de Córdoba, Zona Subbética)
(Sociedad Geológica de España, 2001)In areas of the Median Subbetic, as in the Sierra of Priego in the southeast of the province of Córdoba, outcrops of Jurassic subvolcanic basic igneous rocks appear. In this area the pelagic sedimentation, has been controlled ... -
La Formación Marín: redepósito de material jurásico durante el Mioceno (zona Subbética)
(Sociedad Geológica de España, 1990)An important volume about resedimented materials during the Burdigalian has been confused with the oolite Dogger even today. This article determines the Marin Formation, litostratigraphic unit that includes these rocks. ... -
In memoriam Andrés Pérez Estaún (1947-2014)

Influencia del paleokarst en la mineralogía de arcillas del Lias de Algarinejo (Subbético medio)
(Sociedad Geológica de España, 1989)A clear relationship exists between the kaolinite content of the mid-Domerian to mid-Toarcian rocks of the Algarinejo section and the emersion at the same time of the Loma de las Ventanas section some 10 km away. A model ... -
Influencia del subvolcanismo en la sedimentación pelágica del Jurásico medio (Sierra de San Pedro, provincia de jaén, Subbético medio)
(Sociedad Geológica de España, 1999)In areas of the Median Subbetic, as in the middle Jurassic of the Sierra of San Pedro in the southwest of the province of Jaen, important outcrops of basic volcanic and subvolcanic rocks appear. In this area the sedimentation, ... -
Interaction between sedimentation and submarine volcanism (Jurassic, Subbetic, Southern Spain)
(Sociedad Geológica de España, 2000)Se estudia la relación entre vulcanismo submarino y sedimentación carbonatada principalmente pelágica en el margen continental pasivo que actualmente aflora en el Subbético. Existen dos grupos principales de relación entre ... -
Isótopos estables de carbono y oxígeno de los rellenos de calcita (falsa ágata) y su interés paleoambiental
(Sociedad Geológica de España, 1988)The isotopic composition of modern calcite fills (onyx marble) in fractures and related caves is studied. Carbon and oxygen stable isotopes in this material are similar to the vadose speleothems (stalactites and stalagmites) ... -
La Formación Milanos en el Subbético Medio (Jurásico superior): definición y descripción
(Sociedad Geológica de España, 1996)The Milanos Fm (Upper Kimmeridgian-Tithonian) is defined and characterised as a new formation belonging to the Middle Subbetic (External Zones of the Betic Cordillera). It is composed by marly limestones, marls and ... -
Liesegang rings in pelagic limestones: genetic considerations
(Sociedad Geológica de España, 2000)Liesegang rings have been recognized in Middle Jurassic pelagic marly limestones of the Subbetic, Southern Spain. The rings of these structures consist of iron hydroxide concentrations and/or small textural changes and are ... -
Una modificación al modelo genético para la Formación Molicias (Tortoniense superior, Depresión de Guadix, S de España)
(Sociedad Geológica de España, 1988)The Molicias Formation has traditionally been interpreted as being a basinward prograding, platform-talus-basin system, deposited in a relatively rising-sea-level environment. The proposed modification to this model is ... -
Plataformas carbonatadas aisladas (guyots) en el Jurásico del Subbético
(Sociedad Geológica de España, 1999)In a sector of the Southern Iberian Continental Margin (in the Median Subbetic) isolated carbonate platforms developed over volcanic edifices, forming guyots, during the middle Jurassic. In these platforms, the sedimentation ... -
Sedimentación pelágica jurásica sobre rocas volcánicas submarinas en Algarinejo (Provincia de Granada, Zona Subbética)
(Sociedad Geológica de España, 2000)In the Median Subbetic (Algarinejo locality) submarine volcanic flows interbedded in pelagic Middle Jurassic sedimentary rocks have been previously described. Levels of caldsiltites with wave lamination and hummocky ... -
Tempestitas en el Subbético medio (Fm. Milanos, Jurásico superior). Sus características y facies relacionadas
(Sociedad Geológica de España, 1996)We have recognized and analysed tempestites, made up by calcisiltites and calcarenites with chert and hummocky cross-stratification (HCS), in the Milanos Fm (Upper Jurassic) of the Middle Subbetic (Betic Cordillera). The ... -
Turbiditas oolíticas cretácicas al norte de Vélez Blanco (Subbético interno, provincia de Almería)
(Sociedad Geológica de España, 1990)In the Internal Subbetic Middle and Upper Cretaceous oolite turbidites occur. Two main type of facies are present: 1) Conglomeratic beds (A2 facies) composed of clasicts of very different lithologies and ages, and 2) Oolit ...
