Associated to the Navajún pyrite deposits (Cameros basin. North Spain), it appears a lutite horizont with decimetric carbonate concretions normally septarized. This septarization occured during early diagenesis, and it provided a suitable place far precipitation of a quite complex cement sequence. This sequence evo/ves from ca/citic cements precipitated during diagenesis to minera/s such as pyrite, ch/orite, quartz, barite and ca/cite precipitated during hydrothermal metamorphism that affected this area.
