Messagerie francophonePoullaouen...gypse?

22nd Nov 2006 10:27 UTCJean-Marie LAURENT

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.)

Many thanks Uwe...

Fe sulphate...have you any idea ? Halotrichite may be...

23rd Nov 2006 07:03 UTCJean-Marie LAURENT

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..
