| Sumario: | New data on the geological setting of the el Pedroso magnetite deposits (Southern Iberian Massif) are presented. Magnetite is found in a carbonate band whih was skarn transformed by the El Pedroso granitoid intrusion. The skarn is thought to be of lime type because of the typical association of Ca minerals found. From this study, the following geological characteristics can be deduced: a) all the metamorphic processes occurred on the magnetite deposit country rocks can be reasonably explained as a simultaneous process of contact metamorphism and deformation, b) metamorphism reached up high grade conditions, locally producing anatexia of the country rocks, and c) Fe was concentrated from the El Pedroso granitoid, which is Fe very rich (8-12 %), by the skarn process. |
