Abstract
[Resumen] El presente trabajo concierne a la aplicación de estudios geo16gicos y tectónicos en la prospección minera de determinadas masas de sulfuros en Aznalcollar, región oriental de la Banda Piritosa Ibérica. Del análisis de datos petrológicos, sedimentarios y tectónicos, se ha podido establecer: 1°) El control estratigráfico y las facies favorables de las rocas encajantes de las masas de sulfuros. 2°) La estructura imbricada como resultado de deformación polifásica. Se describe las diferentes relaciones entre el plegamiento y cabalgamiento 3°) Secuencia litoestratigráfica del complejo volcánico sedimentario de la zona, a partir del cual, las masas de sulfuros al sur (Higuereta-Cuchichón) y la del norte (Caridad) corresponden a un mismo horizonte mineralizado.
[Abstract] The present work is concerned to the application of the geological-tectonic studies on mining prospection of specifyed massive sulphide orebodies from Aznalcollar area, eastern region of the Iberian Pyrite Belt. Analyses of petrological, sedimentary, and tectonic data, habe make known : 1°) The lithostratigraphic controls and favourable facies of the close host-rocks.2°) The imbricated structure as result of poliphase deformation, in wichthe relationships between folding and thrusting are debated. 3°) .Lithostratigraphic secuence of volcanic-sedimentary complex, in wich massive sulphi de orebodies on the north side of the Aznalcollar area (Caridad Mine) and (Higuereta-Cuchich6n Mines) to the south, are related to the same volcanic-sedimentary layer.
