JFD249AQ1: In the 1980s-1990s little was known about these well-crystallized goethites from Tizirine-Sidi Rahal, which used to be labeled “Pyrolusite”, because their main seller, Infles Abdullah, had his basar near the Imini manganese mine.
Later it was learned that the crystals were pleochroic and when analyzed were confirmed to be goethites.
This fine piece comes from that glorious period, associated with a group of Calcite crystals, although Calcite, curiously, is a species that is not abundant in these vugs.
