Show Labuntsovite Group Photos (189)





A very large group of porous titano- and niobosilicates (monoclinic, pseudo-orthorhombic or orthorhombic).
Seven subgroups are distinguished, each corresponding to different structure types (Chukanov et al., 2002).

One of these is the Nenadkevichite Subgroup which comprises the orthorhombic members.
