The cancrinite group are minerals with hexagonal and trigonal crystal systems with various anions and cations located in cages within the main frame.
14.
The accessory minerals are apatite, cancrinite, calcite, titanite and iivaarite, a dark-brown titaniferous variety of melanite-garnet.

Litchfieldite is composed of two varieties of feldspar ( mostly albite but also some microcline ), with nepheline, sodalite, cancrinite and calcite.

They then performed a complete chemical and structural analysis which confirmed that the substance indeed was a new feldspathoid species related to the cancrinite-sodalite group.
17.
All minerals in the cancrinite-sodalite group have a similar framework, however, the number of layers of stacking are key in differentiating each mineral.
18.
In the volcanic region of Latium, Italy, a few scientists found some crystals with hexagonal morphology while doing a study of the cancrinite-group minerals.
19.
Cancrinite's twelve-ring channel cage prefers larger cations and thus preferentially selects Ca2 + over two Na + s when the former is present in solution.
20.
Within the group, there are various types of cages such as the cancrinite cages, the sodalite cages, the liottite cages, the losod cages among many.
