| Sumario: | [EN] Close to the mouth of the Jaruco River, almost 30 km East of La Habana, Cuba, three marine planation surfaces built of reefal limestone (Middle Miocene to Upper Pleistocene) are developed. Eighteen caves concentrated in a 3 km2 territory have been explored. Five of them have been recently resurveyed and studied. Three of them reach the local water table whose altitude and mineralization shows the seawater influence almost 1.5 km inland. Cave morphology, sediments and speleothems sustain a hypothesis of an origin and evolution linked to the modifications of the coastal line and to the formation of the marine planation surfaces. The evolutionary scheme comprises a first episode of void development below the water table related with the mixing of different mineralization waters, a possible neotectonic uplift that dewatered those voids followed by a second episode of void development at a lower depth together with an intense corrosional process accompanied by a residual terra rossa sediments filling of the voids. Subsequently, a large breakdown process took place and one or several speleothem generations are recorded in the upper cave levels. |
