| Sumario: | [eng] In Mallorca Island, the genesis of caves and solutional morphologies that characterize the eogenetic endokarst of the littoral fringe attain particular intensity within the Upper Miocene carbonate rocks. Dissolution processes occur preferentially in the mixing zone between freshwater –of meteoric origin– and marine waters, all along the coastal areas. The submerged passages and chambers, existing in the caves of Migjorn and Llevant regions of the island, show a high diversity of solutional features that are categorized into four groups according to their dimensions, the forms they present and the genetic processes involved. The resulting morphologies are conditioned by the existence of significant lithological differences, of textural character, within the Upper Miocene calcarenites where caves develop, due to environmental variations between the reef front facies and those corresponding to lagoon facies. The difficulties encountered when cataloguing and systematizing the primary morphologies should be, so often, attributed to the difficulty in ascribing solutional features to a certain typology, as there are juxtapositions of different classes, with intermediate forms and different degrees of intensity in the process of dissolution. At the same time, variations in the size of solutional morphologies also increase their difficulty of classification. The inventory of forms has been structured into 4 different categories: megaforms (organization of the cave systems), macroforms (morphologies from hectometric to decametric order), mesoforms (morphologies from decametric to metric order) and microforms (morphologies from metric by centimetric order). Some of the morphologies can be found simultaneously in two different categories. |
