Abstract

Cala mine is located in the southwest of the Iberian Massif, in the Ossa-Morena Zone (OMZ). Due to the complexity of its mineralisation, there has been much debate in recent years but, according to recent studies, it is interpreted that part of the mineralisation is related to a calcic skarn that outcrops nearby. In this work, garnets from this skarn have been dated using the U-Pb geochronology by LA-ICP-MS, and the obtained age is 335 ± 1 Ma. Calcic garnets (Gros52-59Andr40-44) show homogeneous major elements distribution. A weak chemical zonation can be observed in trace elements and REE, more evident in trivalent elements. This chemical homogeneity has been related to a stable system, where P-T conditions have remained quite stable.
