CONDICIONANTS LITOLŇGICS I ESTRUCTURALS DEL CARST A LES ILLES BALEARS
Abstract:

The lithology and structural setting of the rocks which form the island of Mallorca are magnificent bases on which karstic phenomena develop. Almost every geological period is continually represented here, from the Carboniferous to the Pleistocene (only part of the Upper Cretaceous and Lower Paleogene being absent). The approximate thickness of the stratigraphic sequence is 3,000 m in which carbonate deposits (not only limestones but also dolomites) constitute the most important lithologies. The main structure consists of thrust sheets imbricated in a NW transport direction. Such deformation took place during the alpine orogeny. Furthermore, the existence of impervious materials from the Keuper at the base of the thrust sheets, added to the imbricate thrusts system structure, cause permeable zones to remain isolated by areas of impervious material. The development during the post-orogenic phase (Late Miocene) of a carbonate reef deposition, forms a large tabular slab where the phenomena related to coastal karst have its maximum expression. Menorca, can be divided into two very distinct parts. The northern half or Tramuntana, well structured, but dominated by the presence of siliceous material from the Devonian with a couple of large slabs of Mesozoic limestones and dolomites, quite different from Migjorn, in the south, where the Late Miocene calcarenites and calcisiltites clearly dominate. Eivissa can be assimilated to the same structure of the Tramuntana mountains of Mallorca, which are almost exclusively dominated by carbonate materials, particularly the dolomites, but the limestones from the middle Triassic and the marls (Cretaceous and lower Miocene) are very abundant. Formentera is dominated at both ends of the island by sea cliffs cut on Miocene reefal limestones joined by an isthmus where Pleistocene aeolian calcarenites outcrops.
