Nuevos datos geológicos sobre las mineralizaciones de grafito de la Banda Metamórfica de Aracena, Huelva (Macizo Ibérico Meridional)

Description

In this work a detailed geological map of the graphite mineralizations of the Aracena Metamorphic Belt (SW Iberian Massif) is shown. Three types of mineralizations have been distinguished according to lithostratigraphic and structural criteria: 1) Stratiform deposits related to gneissic lenticular bodies embedded within a complex calc-silicate sequence 2)Veinlets of graphite cutting across mafic granulites; and 3) Disseminated graphite within gneisses and quartzites belonging to the Fuente del Oro series. Only the first type of mineralizations could have an economic interest.
