• Resumen

  • In the Valencia del Ventoso plutonic complex it has been detected the basal part of a previous stock formed by cumulates. This accumulative sequence is subdivided in base of textural criteria in five zones, called from the bottom to the upper part Zone I, II, III, IV and V respectively. Textural, modal and mineralogical criteria indicate the existence of at least two chamber recharges. The principal fractionation mechanism that takes place during the early stages is related with continuous convection, but the progressively thermal equilibrium with the host rocks led to crystal settling mechanism. With these two continuous processes, take place eventual processes related with compaction and chamber recharge.
