Resumen:
This study is a new contribution to the facies/microfacies and geochemical characterization of the marine jurassic carbonates of Calabozo Formation.  This unit, of Early Callovian age, crops out in the Neuquina basin of southwestern Mendoza province, Argentina. Oxygen isotope  system is the most sensitive indicator of diagenesis, and the carbono isotope system retained best the primary isotopic characteristcs.  Limestones deposited in the deepest areas of the basin, are the best preserved and their 13C signature is in concordance with Callovian unaltered marine carbonates.
