| Sumario: | [eng] Es Dolç des Coll Baix is a submarine spring located in the Serra de Tramuntana, on the coast of Alcúdia. The cavity is related to the tectonic structure formed by an overturned syncline in Jurassic Malm limestones. Its genesis surely combines the greater aggressiveness of the mixing zone of fresh and salt water strongly linked to the source itself. The accumulation of consolidated marine sands, which are covered with flowstones and other speleothems, has suffered the erosive action of the waves generating false floors that characterize and determine the current morphology of the underwater passage. The cave has a SW direction along a linear distance of 150 m, with a total length of 225 m and a depth normally between 2 and 6 m. The ceiling presents abundant air-filled bells and chambers. The terminal part of the cave shows temporarily the accumulation of remains of the phanerogam Posidonia oceanica; presumably, the phenomena of decomposition and alteration of these organic remains are responsible of the intense whitish color which acquires the upper freshwater layer. |
