Minéralogie de l'indice plombifère de Petite-Hoursinne (Érezée, Province de Luxembourg, Belgique) ; Mineralogy of lead arsenates at Petite-Hoursinne (Érezée, Luxembourg Province, Belgium)

peer reviewed ; Erythrite and mimetite, two arsenates rarely found in Belgium, were discovered near a small mine at Petite-Hoursinne, near Erezée (Luxembourg province, Belgium). That rare occurrence of these arsenates is to be compared with the one observed at La-Roche-en-Ardenne in the same geological Formation (Villé formation, Praguian, Lower Devonian).
