JZ50W6: Pyrrhotite with Pyrite and Quartz

Groups of laminar crystals of Pyrrhotite in rosettes. They are very aerial, of a considerable size and are on a rocky matrix. The crystals of Pyrrhotite, with recrystallized Pyrite on the surfaces of the pinacoidal faces, remain stable in spite of the long time that has passed since they were recovered, very probably due to the presence of the Pyrite.
