Mineralogy and geochemistry of the carbonates in the Calatayud .

The isotopic composition of magnesite [81So = +4.6%0 (PDB) and 513C = -4.0%~], together with the higher concentration in Sr and Na, indicates that this phase probably precipitated from more evolved water. The isotopic values and trace-element contents of carbonates appear to confirm the mineralogical trend from.
