Nerja Caves Information
The caves of Nerja are the formation of karstic cavities, with is origin in the chain of the geological processes occurred within the last 225 million of years. In the period of Triassic significant quantities of the calcareous mud settled down on the fond of the ancient Mediterranean sea, later on transforming into the calcareous- dolomite marble, which a present shelters the Caves of Nerja.
In the period of the alpine orogeny (the end of Cretaceous/beginning of Miocene), started 65 million tears ago, drifts between tectonic layers of Africa and Europe resulted in the creation of the Beticas mountains, such as Sierra Tejeda or Almijara.
The rain abundance in the last 5 million years ( Superior Miocene and Inferior Pleistocene) infiltrated the fissures of marbles stimulating its further dissolution. In this way, huge cavities in which the underground waters circulated were formed. Later on due to the surge of the ground embossment, resulting from the mountain slides in the region in question, the subterranean waters were forced to look for the lower layers to circulate in. In the consequence the caves commenced to refill with carbonate deposits- stalactites and stalagmites.
In the last 800.000 years (Medium Pleistocene and Holocene) the impressive stalactites and stalagmites have been formed thanks to the further settling of calcite. The settlement processes have created subterranean scenary of the Caves of Nerja, which can be admired nowadays.
