About Chevkinite GroupHide

Group of complex and difficult-to-distinguish titanosilicates.
The chevkinite group may be subdivided in members with a monoclinic angle beta of ~100°, and members with beta ~113° ("perrierite group"). Unambiguous identification is often only possible using single-crystal diffraction methods (powder diffraction patterns are very similar).

A larger number of synthetic members have been prepared.
