The Gorges du Tarn meet the Gorges de la Jonte at the village of Le Rozier. The Jonte Gorges are bounded by the Causse Méjean to the north and the Causse Noir to the south. These are carved out by the Jonte River, and offer 20 km of dazzling spectacle before the river joins the Tarn at the village of Le Rozier.
Geology of the Gorges du Tarn
How were the Gorges du Tarn formed?the geology of the Gorges du Tarn
DID YOU KNOW?
The geological bedrock of the Grands Causses is made up of tens of millions of years of accumulated limestone sediments from the Jurassic period. At that time, there was a sea here. Over 1,500 meters of deposits have accumulated over time. The different strata that can be seen on the cliffs bear witness to the millennia that have passed.
The formation of the Gorges du Tarn
It was the Pyrenean and Alpine tectonic movements of the Tertiary period that lifted the Grands Causses. Subjected to opposing forces, they gradually cracked and broke apart. As limestone is a porous, permeable rock, the Tarn and Jonte rivers were able to carve out the impressive Gorges du Tarn we can admire today. This digging began 20 million years ago! Over the millennia, wind and rain also played their part in giving them their current appearance.
