GEOLOGY

The area where the cave is located, comprises part of the rocky mass of Helmos and the hydrologic basin of Aroanios river. The elevation of the cave is around 850 meters. The greater area surrounding the cave belongs to the stratigraphic cohesion Tripolis Zone and Olonos-Pindos Zone and consists of: 

for the Olonos-Pindos Zone:
1) Eocene flysh 
2) Upper-critidic limestone 
3) Jurassic Radiolarites

for the Tripoli Zone:
1) Paleocene limestone 
2) Upper-critidic limestone and more recent deposits:
        α) Latipes with argillaceous copulative tissue 
        β) conglomerate and adobe rock formations.

The cave formation is initially due to tectonic crevices followed by chemical and mechanical erosion caused by the subterranean and surface waters of the hydrologic basin of Aroanios river. These natural events created the Cave of the Lakes, whose entrance has been excavated.  Chronologically, this seems to have taken place during the Glacier Period (1,5 million years ago).
