The discovery of sapphire in the current of 1998 transformed the area. · Ilakaka in 1999. It is in the accesses of the downwards brook named Ilakaka that the first sapphires were found in 1998. The existence of gemmiferous minerals, including corundum was known for a long time in the sandstones of Isalo. French geologists having undertaken research in 1946 in particular. If their discovery did not cause particular interest at the time, several reasons can be advanced : the political instability which reigned after the second world war in the colony, and the fact that the majority of corundums coming from the area of Ilakaka must be heated to be marketed, indeed, a blue stone, but cloudy, could not inevitably let suppose to its discoverers that it would become pure and transparent after a suitable heat treatment. Moreover, knowledge in this field remained summary at that time. In Ilakaka, the arrival of merchants coming from Thailand and from Sri-Lanka changed things, because this group of purchasers became experts in "the " Tsy misy mandronono, tsy misy prix" enhancement of corundum." Thus, the cloudy stones of This sentence is none by everyone in better quality will be often sold as (untreated Sri-Lankan Ilakaka. sapphires) on the international market, this because of It means that : " if the stone is not milky, the difficulties in detecting heating treatment in a stone its owner will not get price for it." from Ilakaka not containing other inclusion only one haze of fine titanium drops, reabsorbed after heating. ( Note: that true untreated Sri-Lankan sapphires are rare.) The excavations follow the gravel deposits which the Impressing holes bore the sandstones of Madagascans call lalam' bato, (the way of stones.) Ilakaka testifying to the fever of sapphire. Ankaboka, one of the many gemmiferous places of the area. · Maromiandry is located The sivany (sifting of gravels) in Maromiandry. 40 kilometers north of the Seldom practiced dry as in this place distant trunk road between from a river. Ilakaka and Sakaraha. The sifting of gemmiferous gravels in river close to Maromiandry. · VOHIMENA VAOVAO, 25 kilometers far from Ilakaka. One of quote headlight of the sapphires production. The higher edges of the rivers abound in sapphires, chrysoberyls, etc. Here in the area of Vohimena vaovao. The sandstones, fragile, have been knife cut by the river. SANDSTONES of ISALO The base of the group of Isalo is entirely continental. Sometimes significant marine incursions and of long duration were introduced into the medium and higher parts. The group of Isalo begins at the top from lower Triassic and continues until the end of the Jurassic means. One separates there: Isalo I, at the base, especially sandy, continental. Isalo II, argilo - sandy with some marine intercalations. Isalo III, argilo - sandy with side passage to great marine formations. The essential characteristic of the Isalo formations is their main constitution of soft sandstones, very permeable, badly cemented which disaggregate easily on surfaces by giving thick siliceous sand coverings. The porous nature of the sandstones constitutes an excellent tank which stores the water of the rains to restore it during the dry season. · Sakalama, 60 kilometers south from Ilakaka. MADAGASCAN CORUNDUMS At the back, ruiniform sandstones of the Isalo range.
