Coco Posted March 6, 2011 Share Posted March 6, 2011 Nala, are you sure it is pyrit on your second pic ? I think it is marcasite (marcassite in french).

Coco Yes Coco it is marcassite nodule,i thought it was some kind of pyrite ?,people say that,but i know very little about minerals,regards Link to comment Share on other sites More sharing options...
Coco Posted March 6, 2011 Share Posted March 6, 2011 Pyrite crystallizes in the cubic system, while the marcasite crystallizes in the orthorhombic one. In your area, we can find "sperkises". It is a marcasite form (its name comes from its strange shape of crystallization).

It is a marcasite form (its name comes from its strange shape of crystallization). Coco Thanks Coco for your expertise "La marcasite est un minéral très semblable à la pyrite. Il a la même composition chimique, la même dureté, la même apparence (couleur jaune laiton à éclat métallique) et se trouve dans les mêmes gisements . Seul le système cristallin est différent : la marcasite appartient au système orthorhombique alors que la pyrite appartient au système cubique."i also found that(in french sorry)regards Link to comment Share on other sites More sharing options...
Coco Posted March 6, 2011 Share Posted March 6, 2011 Yes Nala, pyrite and marcasite have the same chemical formula : SiO2. I think marcasite contains often more molecules of sulfur, it is the reason why it makes it more easily pulverulent and fragile. The nodules which you show us sometimes fall in dust...
