Chantal et Guy...Le service a table est très lent. The iron then combined with the existing minerals to form a highly ferrous grey-green clay, called Following an uplift of the sea floor the sandbank was covered by a saline mangrove swamp and the decomposition of the mangrove leaves led to an increase in humic acid. Finally due to a progressive drying and repeated exposure of the sands to the rain and the open air in a climate first tropical and then becoming more and more dry, the iron oxidised, migrated and was fixed. !1h45 (not counting stops, loop returning to car park)Please bring: Walking shoes with ankle support, hat, sunscreen, water (you have to pass through the Sahara!

This process also created a ferrous crust, which was later mined to feed the blast furnaces for the production of iron.Further south this lateritic alteration process of kaolin continued to such an extent that the siliceous earths which composes the ochres was completely dissolved leaving only iron and aluminium, in the form of bauxite, which was mined in the Var for the production of aluminium.230 million years ago Provence was covered by the sea. La cuisson des pizza au feu de bois ont été très appréciées Nous étions 8 et avions réservé. Once the ore was extracted, the ochre was separated from the sand using techniques of washing and settling. Bon rapport qualité prix. !et à qui elle avait au moins donné une bouteille d'eau!! The ochre ore is therefore a type of clay charged with iron oxide, mixed with a high proportion (80-90%) of sand.The extraction of ochre sands is done either in open cut quarries or in subterranean galleries.
Le repas et le cadre étaient parfaits mais le service était un peu trop pressant. The iron oxide contained in the sediment was concentrated and caused the crystallisation of clay minerals, to which the yellow and red oxides became bound.
Nous n'avons pas été déçus. Text by  Sandra Poëzevara, Directrice du Musée de lâAventure Industrielle in Apt. Transport was managed differently in each period and by each enterprise: by horse-drawn wagons, then by lorry and tip-trailer. Vestige d’un passé récent, les paysages ont été sculptés au gré de l’exploitation des carrières d’ocre. Over time variations in temperature, coupled with the increasing acidity of rainwater combined to erode minerals from the ancient granitic rocks of the Massif Centrale and produce both:While some larger residues form the granitic rocks were washed to the coast and deposited in ancient river estuaries (in the form of gravels and larger pebbles), the finer particles â fine sands, silts and clays reached the open sea.These were then carried by ocean currents, flowing South East, and were deposited to form an immense sandbank parallel to the coast, which was in this period as far north as Montelimar.Today we can find this deposit covering an area more than 100km long, several tens of km wide and sixty metres thick and extending from the southern Ardeche (Departement 07) towards the Var (Departement 83).This sandbank, shaped by the currents and geological time, eventually formed 3 distinct deposits which are now mined in the Vaucluse: for glassmaking sand near Entraigues, for ochre in the region of Apt between Roussillon and Rustrel and for bauxite towards the Var.The ochres of Vaucluse are remarkable and unique because they required the intervention of animal, vegetable and mineral realms coupled with the slow inexorable forces of geological upheaval.The raw material of the ochre comes from the erosion and recombination of clay components of granitic minerals in the form of clays, which result in the formation of kaolin, made from oxygen, aluminium and silicone.
