That gypsum is 1. white or colorless mineral or rock composed of the hydrated calcium sulfate, caso4.2h2o. gypsum rock is an evaporite precipitated from sea water and is therefore soluble in water and may contain dissolutional caves. mineral gypsum is formed in some caves by reactions between the host limestone and sulfates (including sulphuric acid) derived from oxidized sulfide minerals (see pyrite). gypsum, also referred to as selenite, commonly occurs as transparent crystals, blades, needles or fibres in cave clay deposits. a more spectacular form is as fibrous or curved crystals that may develop into cave flowers on cave walls and ceilings, as for example in parts of the flint mammoth cave system, usa, or grow into large, hanging chandeliers, as in lechuguilla cave, new mexico [9]. 2. a mineral composed of hydrous calcium sulfate [10], caso4. h20.?

Les karsts dans le Jurassique ardéchois

Abstract:
ARDECHE KARSTS IN THE JURASSIC LIMESTONES - The southern part of the department of the Ardeche consists of numerous karstic zones. In these places, there are several caves, some of which are well-known: The Sauvas-Cocaliere’s cave, St Marcel’s cave... But speleological and scientific studies have mainly focused on the Cretaceous karst. The Ardèche gorges cut through this area. The Jurassic karsts although lesser known deserve to be studied in depth for their hydrogeological and geomorphologic interest. The surface landforms show evidence of the intense karstification, but it is deep down underground that these phenomena are most impressive. Four elements characterise the originality of these plateaus: the very strong amplitude of outflows in relation to the structure, the active grinding and the neotectonic affect most of the caves, the importance of the fillings which are sometimes allochtonous and the probable age of the caves. In most cases, investigating them means using subterranean diving techniques.
