ON THE ROLE OF HYPOGENE SPELEOGENESIS IN SHAPING THE COASTAL ENDOKARST OF SOUTHERN MALLORCA (WESTERN MEDITERRANEAN)
Abstract:

The Migjorn region is one of the main karst areas in the island of Mallorca (Balearic Archipelago, Western Mediterranean) and has abundant coastal caves developed in Upper Miocene reefal carbonate rocks. In general terms it is an eogenetic karst platform in which littoral mixing dissolution processes usually represent the most important speleogenetic mechanism to be considered. Nevertheless, recent explorations in Cova des Pas de Vallgornera (Llucmajor Municipality), that nowadays has development exceeding 59 km of passages, raise interesting questions about the genesis of this outstanding littoral cave. An artificial entrance located at about 500 m from the coast line gives access to a complex assemblage of chambers and galleries, partially drowned by brackish waters, whose spatial disposition and morphological characteristics are strongly conditioned by the internal architecture of the Upper Miocene reef. The inner part of the cave consists of an extensive network of galleries that contain morpho-sedimentary features pointing to the possible participation of hypogene speleogenesis in the excavation of the system. Solutional features related to rising flow are abundant, together with Mn- and Fe-rich deposits and some minerals not known up to the l present in other caves of the region. The hypogene speleogenesis mechanisms that may have acted in Cova des Pas de Vallgornera could be associated with the feeble geothermal anomalies existing currently in the Llucmajor platform, related to important SW-NE faults which delimit the Campos subsidence basin in the southern end of Mallorca Island. The genesis of the cave system seems to be a complex matter including, besides coastal mixing processes and epigenic meteoric recharge, the participation of hypogene speleogenesis in an eogenetic unconfined setting.
