Perfiles geoquímicos y luminiscencia en las cámaras y concha de Crassostrea sp. de la Formación Zufía, Navarra (Albiense superior-Cenomaniense inferior). Parte II

Shells of the oyster Crassostrea sp. from the Zufia Formation show chambers filled with different diagenetic carbonates that record a complex diagenetic history. Evidences of «burial» diagenesis, represented by the formation of ferrous «saddle» dolomite, suggest high formation temperatures. However,...
