“Ferriakasakaite-(La) and ferriandrosite-(La) crystal. These two minerals are visually indistinguishable, and are also identical in appearance as vanadoallanite-(La). In fact, ferriakasakaite-(La) and ferriandorosite-(La) were identified during an attempt to identify more vanadoallanite-(La) for further studies. All three minerals are found in the same rhodochrosite/tephroite veins in a ferromanganian ore.
