Hancockite with Hendricksite & Andradite


Hancockite with Hendricksite & Andradite

7 x 5 x 3.5 cm - Sm Cabinet 
CaPbFe3+Al2(Si2O7)(SiO4)O(OH) (RRUFF)
Franklin, Sussex Co., New Jersey, United States

A good specimen with a lot going on. It is coarse crystalline with patchy red areas filled with tiny acicualr crystals of glassy, red to pink Hancockite, formerly Epidote-(Pb) and formerly formerly Hancockite. Someday, it may be Epidote-(Pb) again....nonetheless the same mineral. In association is the mica group member Hendricksite, a bronzy platy mica. The orange-yellow I believe is Andradite. Ex. Dr. David H. Garske & Paul B. Moore collections.
