Jiménez Berrocoso, A.; Zuluaga, María Cruz; Elorza, Javier (Sociedad Geológica de España, 2003)

Inoceramid shells (four individuals) from deep facies sediments of the Plentzia Formation) (Santonian, Basque Arc) have been analysed to determine their elemental chemistry (Mg2*, Sr2*, Na+, Ba2*, Fe2* and Mn2*) using ...

Geoquímica microestructural en Praeradiolites ciryi (Hippuritacea, Bivalvia, Cretácico Superior de Gredilla de Sedaño, Norte de Burgos, España)Microstructural geochemistry of Praeradiolites ciryi (Hippuritacea, Bivalvia, Upper Cretaceous of Gredilla de Sedano, Northern Burgos, Spain)

Regidor Higuera, I.; García Garmilla, Francisco; Zuluaga, María Cruz; Elorza, Javier (Sociedad Geológica de España, 2003)

The detailed geochemical evolution along two transects of the shell of one specimen of Praeradiolites ciryi is examined along annual, seasonal and fortnightly («doublet») sclerochronological records. The analyzed specimen ...
