Bonjour à tous.
J'ai mis 2 photos dans la rubrique " identity help "
Il s'agit d'un micro échantillon de scories de Pouallouen ( 29 )

Excellente journée à tous.

Could be an Fe sulphate. (Or some chloride.)

bonjour:

assez classique dans les scories de surface de Poullaouen : gypse tardif ( le gypse "primaire" est en beaux cristaux incolores.

D'accord avec Philippe
gypse très récent;pour ceux qui ont ramené des marcasites de Plumelin et qui les ont "oubliéés" dans la cave , elles en sont maintenant couvertes..
