| Résumé : | This paper concerns the petrological and geochemical studies of a vein and its associated iron crust. The hypogene assemblage (chiefly marcasite and accessory sphalerite, galena and chalcopyrite) and the supergene assemblage (goethite, hydrohematite and lepidocrocite) are described and the genetic significance of the main structures discussed. A model for the oxidation and hydrolysis of the primary ore mineral is presented and an attempt is made to establish a geochemical balance sheet. Taking into account the lithology, the geochemistry and the mineralogy of the host carbonate rocks, the hypothesis of emplacement of the vein by lateral secretion is discussed. -T.R. |
