Caractérisation des formations argileuses de la cave N°46 du Djebel Debbagh (région de Guelma).

Abstract

Djebel Debbagh is the most important massive of the neritic pier constantinois (Algerian North-Est), this massive corresponds to native lands (indigenous) of Jurassic and cretaceous age, overcome by allochthounous formations of Tellian units. The Djebel Debbagh deposit is characterized by its resources with a mining potential, this zone contains two types of mineralization (kaolin and iron hats). The kaolin mineralization of Djebel Debbagh is hosted mainly in karst caves formed in limestone of Albo-Cenomanian age. Depending on their shape, these karst caves are subdivided into bowl, ditches and tube where it locate the most interesting kaolin from an economical perspective cellars. There are ssociated with ferruginous concretion masses considered as impurities from the obtained ore such as the alunite, limonites, etc. Industrially, Djebel debbagh’s kaolin is subdivided into three categories (DD1, DD2, DD3) according to color, its content in alumino-siliceous material and its purity. According to field studies, the karst mineralization of Djebel Debbagh is consideredasa hydrothermal mineralization. The kaolin ore extracted from the Debbagh mine is processed at the Guelma ceramics factory, which is considered to be one of the main manufacturers of ceramic products in Algerian eastern.
