Oxygen and strontium isotope composition of the external and external-leucocratic facies suggest an origin essentially by partial meeting of crustal materials for the postkinematic Caldas de Reyes granitic s.l. massif. On ...

Fan deltas occur in a wide range of tectonic and sedimentary settings which are likely to generate a varied mosaic of facies associations. Fan delta deposits provide a good geodynamic record of basins as illustrated by ...

A biostratigraphic study of Campo section (Ilerdian parastratotype) has been carried out by means of planktonic foraminifera and calcareous nannoplankton. The most standard and recent biozonations for Lower Eocene (Ilerdian ...

The waters saturating the Balerma-Las Marinas Unit, one of three that form the Campo de Dalías region, locally have high total salt contents whose probable origin is related to mixing with trapped salt waters within ...

Lower Cretaceus sediments (Hauteriviam to Barremian) in Northern Iberian Chain (Aguilón, Zaragoza) are deposited in a shallow lacustrine environment. Three main shallowing upward sequences are developed. In the upper two ...

Facies analysis of the Upper Jurassic sequence, exposed along Cabo Mondego sea cliffs, suggest that their deposition occured under nearshore environments. These environments were controlled by tides and in some cases by ...

In this paper we attempt to sketch the structural pattern of the Boal pluton (WestAsturian-Leonese Zone) and provide new data which account for a pasive mode of emplacement and a subsequent structural evolution probably ...

During anatexis of metapelites, the trace element fractionation can't be modelled by the mathematical expressions derived by Shaw (1970). In this case, the equations of Hanson (1978) should be used, when the mineralogy of ...

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 ...
