That sulfate minerals is minerals containing the so4 2- radical, formed by precipitation from water. the most common are the anhydrous and hydrated calcium sulfates, anhydrite (caso4) and gypsum (caso4.2h2o). sulfates are deposited as a generally minor component of most carbonate successions, but due to their high solubility they may not survive subsequent dissolution by ground water. even if they survive subsequent dissolution by ground water. even if they survive at depth, they tend to dissolve as they are raised nearer to the surface following uplift and erosion of overburden. removal of sulfates by dissolution may contribute to the early establishment of secondary permeability in limestone sequences. sulfate solutions have a limited corrosional effect upon calcium carbonate, but may also be oxidized to produce sulphuric acid, which is highly corrosive of limestone.?

Modes de positionnement topographique et électromagnétique d’un siphon. Exemple du Qattine Azar (Liban)
Abstract:
Topographical and electromagnetic positioning of a deep sump: Qattine Azar (Lebanon) - Wasting, pollution, climatic modifications, urbanisation and demographic explosion will generate a serious water scarcity in many countries, among them, the Middle East. In Lebanon, after the discovery of an important underground river, is established a water impounding project, needing a 280 meters drilling through limestone. The author describes the topographic method used to survey the cave and to set up the future drilling. The survey has been confirmed by an electromagnetic positioning ARCAS (radiolocation) perfected by Joan Erra. The accuracy of the two determinations is estimated.
