The hill of Mirabeau corresponds to a large anticlinal fold (arched). This fold is cut by the Durance River into a narrow gorge, which provides a spectacular view of the internal structure of the fold on the right bank. Location: Mirabeau (84) Site type: Remarkable geological formation, Remarkable relief Parking: Available This large anticline is asymmetrical, tilted towards the northeast. Erosion has attacked its core to reach the marly layers of the Upper Jurassic, which are the oldest rocks in the Luberon Regional Park. Its flanks are composed of massive terminal Jurassic limestones. On its eastern flank, at the level of the bridge, the limestone layers are tilted vertically. The Durance River has cut through the fold perpendicular to its axis, a feature known [...]

This site reproduces and illustrates on a smaller scale what happens on a larger scale in the Luberon massif. It is a "miniature Luberon." Location: Vaugines (84) Site type: Remarkable geological formation Parking The site of Déboulière, sometimes called La Garrigue, is 2.5 kilometers long and 500 meters wide. It stands out distinctly in the landscape as a small hill emerging from the cultivated plains. This small structure is an anticlinal fold (arched up), situated in the midst of the Durance plain. The particularity of this anticlinal is observable on its southern flank: Hauterivian limestones, dating back 130 million years old, are covered by 20 million years old Miocene marine sands, and then, again, by Hauterivian limestones. The sands were deposited on the Lower [...]

Le village de Viens, perché sur le rebord du plateau des Courennes, offre vers l’Est une splendide vue balayant les paysages de la Montagne de Lure au Luberon. Et n’oubliez pas d’aller visiter le cœur du village. Passé la ceinture de remparts, se découvre un dédale de ruelles et de places, bordées de belles demeures.

The Earth is a living planet animated by movements. This results in deformations, such as folds, fractures and faults like the particularly impressive one that overlooks the village of Lioux. Location : Lioux (84) Site type: remarquable relief, viewpoint Parking The Madeleine Cliff, which is 7 kilometers long and 80 meters high, is a magnificent escarpment of a fault. A fault is a fracture in the rocks with a relative displacement of one block with respect to the other along a plane called the fault plane. Movements of compression, extension, or shearing cause different types of faults: normal, reverse, and strike-slip. The Lioux cliff highlights the presence of a normal fault oriented NE-SW within the massive and thick limestone that forms the large mass [...]

Located at the eastern end of the Luberon, the Volx Rocks appear to be a homogeneous rock formation. In reality, they are made up of limestone blocks cemented together. They witness the activity of the Moyenne Durance Fault approximately 30 million years ago. Location: Volx (04) Site type : geological formation Parking The Volx Rocks correspond to a large anticlinal fold (an arched fold), which exposes the ancient rocks that outcrop further east in the Grand Luberon. This anticlinal structure is highly eroded in its center and is carved by two large valleys, Sarzen and Margaridètes, which reveal its marly core. Erosion here is spectacular, with intense gullying in the soft marls. The Fontamaurri stream (source of the Fontaines) emerges at the contact with [...]

The village of Saint-Saturnin-lès-Apt is located on the southern slope of the Monts de Vaucluse. Built on a rocky spur, it offers an exceptional panorama of the Luberon, the Alpilles, and the Monts de Vaucluse, as well as a stunning view of the plain between Roussillon and Villars. Location: Saint-Saturnin-lès-Apt (84) Site Type: Remarkable village, Scenic viewpoint Visit Duration: 1 to 2 hours Saint-Saturnin-lès-Apt is a quintessential Provençal village nestled on the southern slopes of the Monts de Vaucluse. To the north of the village, the Lower Cretaceous limestone outcrops are visible. To the south, you will find Aptian marls. As you descend toward Apt and Gargas, these marls are covered by alluvium and topped with small hills where tertiary sands, limestone, clays, and [...]
