JFD29AN6: Prehnite with Quartz and Epidote
It's been a long time since these unique prehnites were seen for the first time, from a remote locality in the deep South of Morocco. Due to the difficulties caused by being close to the border, the work was abandoned and, although pieces from this locality reappear sporadically due to individual adventures, it has never become a classic Moroccan locality despite the fact that it could easily qualify due to the richness of what is apparently there.
