Aspectos composidonales de los piroxenos ígneos del magmatismo básico del sinclinal de Almadén. Implicaciones petrogenéticas
(Sociedad Geológica de España, 1994)Chemical composition of igneous pyroxenes in the basic rocks from the Almadén syncline shows important differences between basaltic lavas and olivine diabases (Silurian to Devonian in age), and quartzdiabases on the other ... -
Aspectos petrológicos , geoquímicos y metalogénicos del magmatismo intraplaca en distintos contextos y edades geológicas
(Sociedad Geológica de España, 1996)Different ocurrences of basic-ultrabasic rocks ranging in age from Precambrian to Mesozoic reveal that intraplate magmatism is a suitable target for exploration of Ni-Cu-PGE ores (and locally, Hg ores'). Long travels o f ... -
Estudio comparativo de los minerales de la fracción pesada en los sedimentos de las terrazas del Río Guadalete y fondos de la Bahía de Cádiz
(Sociedad Geológica de España, 1996)Heavy minerals of sediments from bottom of the Bay of Cádiz and terraces of the Guadalete river have been studied, for establish the genetic relationships and source areas. The use of surface feature analysis using SEM ... -
Estudio preliminar sobre las facies volcaníclásticas de la Formación Zamoranos (Trías Subbético)
(Sociedad Geológica de España, 1993)In some outcrops o f the Trias o f facies Keuper in the Central Subbetic Zone has been defined the Zamorano Formation, dated as Norian. In this formation is possible to identify conglomerates with pebbles of different ... -
Evolucìón petrogenética del magmatismo bàsico mesozoico en las Zonas Externas de las Cordilleras Béticas (S. España)
(Sociedad Geológica de España, 1996)Mesozoic basic magmatism from the External Zones of the Betic Cordilleras consisted of two magmatic events. The first one began at the end of the Triassic and the second developed during the Jurassic. Whole-rock geochemical ... -
Geoquímica de los materiales Pelíticos Cámbricos al Noroeste de Zafra (Badajoz)
(Sociedad Geológica de España, 1996)Cambrian formations from NW of Zafra are composed of pelitic sequences distributed along the Lower Cambrian (LC) up to the Middle-Upper Cambrian (MUC). These sedimentary sequences have a more sandstone component in LC with ... -
The largest mercury anomaly on Earth (Almadén, Spain): a mantle-derived feature?
(Sociedad Geológica de España, 1998)The Almadén Hg deposits are associated with deeply altered magmatic rocks, which main features are briefly described here. Geochemical, including isotopic, data on these rocks suggest that they are derived from deep mantelic ... -
Origen de escapolitas asociadas a doleritas triásicas del Norte de la provincia de Cádiz
(Sociedad Geológica de España, 1996)Scapolites are present in some doleritic tectonic blocks C'ophites" )in the External Zones o f the Betic Cordilleras, In Northern of Cadiz province. These scapolites fill veinlets and replace plagioclases from the dolerites ... -
Rocas granitoides calcoalcalinas altas en potasio en la Zona Centroibérica: el área Garlitos-El Borracho
Donaire Romero, Teodosio
; Pascual Martínez, Emilio; Higueras, Pablo L.; Morata Céspedes, Diego (Sociedad Geológica de España, 1996)
New petrographic and chemical data on the Garlitos pluton and other associated igneous rocks in the Almadén area have shown a high-K calc-alkaline character and clear simiarities with other calc-alkaline granitoids, in ...
