Relaciones entre la hidrología subterránea y la estructura geológica en la Sierra de Tramuntana de Mallorca (Islas Baleares)

Abstract

The overall structure of the island of Mallorca consists of a set of horsts and grabens which are bounded by Upper Miocene-Quaternary listric normal faults. Horsts are segments of a Lower Miocene thrusted and folded belt and constitutes the Sierras. The basins developed at the grabens, which are filled by Upper Miocene-Quaternary sediments. Groundwater flows from the horsts to the grabens. At the horsts adjacent aquifers exists because of its geological structure (imbricate thrust system), whereas at the grabens aquifers are superposed due to the horizontal sedimentary infilling. Major springs, very important for water supply to Palma, are located at the listric normal faults
