Cave "Cueva del Rull"

The Rull Cave discovered in 1919 by José Vicente Mengual (Uncle Rull) when to go hunting with his dog following a rabbit, it entered into a hole, which also brought in a ferret to do it out not leaving any. The next day he tried to remove some stones from the hole and found the cave that bears his nickname.

In the sixties, due to increased tourism, "Uncle Rull" open to the public decides renovating some hallways.

Currently owned by the municipality, is conditioned and open to the public from September 16, 1995.

Geological Atmosphere Vall d' Ebo

From the geological point of view , La Vall d' Ebo is located in a region with such interesting problems which since ancient times have attracted the attention of many professionals and especialistas.Sus geological features correspond to the eastern branch prebetic , in the vicinity of outermost edge over the Alps of south folding peninsula. The stratigraphy is varied and complex , encompassing the stratigraphic column from the Triassic ( Keuper ) to the Quaternary . Mesozoic materials are represented by a diapiric basis Keuper and continuous sedimentation from the Dogger to the Senonian . On this set has a second great cycle discordant sedimentary Tertiary materials ( Miocene ) . Finally, an extensive and powerful bit quaternary coating extends from the edge of the reliefs Mesozoic and Tertiary to the sea.

The Cova del Rull has developed in Miocene conglomerates composed of rounded limestone gravel bowling and it covers a silty clay matrix and have a foundation of highly variable calcareous.

At about 100 meters from the entrance of the cave , and going west on the road, a cross-fault to it, put in contact with marl conglomerates facies "Tap " . The massif is affected by subvertical joints and open. The cave owes its existence to both the dissolving action of water on limestone components of the clusters , and your drag action of silt -clay matrix , and which should be added the combined action of erosion and partial subsidence , usually located.

The cave formation is also linked to other factors geological tectonic in nature , such as faults and folds , translated into a fracturing of the rock mass that allows the entry of water and its movement inside of it. Slowly and steadily the water flow has been eroding Cie and widening fractures which has circulated . Under certain conditions of pressure and temperature has been infiltrated water dissolved CO2 from the atmosphere or the existing ground by bacterial action , forming an acid but weak attacks the calcium carbonate of the limestone (insoluble in water ) , becoming calcium bicarbonate (soluble) , which is dissolved and transported by water. A change in existing conditions can reverse the chemical reaction , depositing calcium carbonate in the form of stalactites and stalagmites and releasing again CO2R is apparent that the growth process of the cave is only possible with a continuous circulation of water. If the flow stops , the development of the cave is limited to that caused by subsidence.

Today, the Rull Cave remains one of the few Spanish caves open to the public up who are still continuing their training process.
