• A mineral of Cronstedtite has been identified, by the first time in Spain, in the Fe-Pb-Zn ore deposits of Sierra de Cartagena (Spain). Cationic composition was determined by Electron Microprobe analysis. Thermogravimetric, X Ray Diffraction and Infrared Spectroscopy were used to determine its thermal dexydroxilation process. A kinetic study of this process was also undertaken.
