| 1. | Biotite, cancrinite and sodalite are characteristic of this rock.
|
| 2. | Nepheline generally shows partial alteration into natrolite and cancrinite.
|
| 3. | It is essentially a microcline, sodalite and cancrinite variety of nepheline syenite.
|
| 4. | Sodalite transforms into cancrinite when exposed to high temperature.
|
| 5. | The mineral of cancrinite is named after him.
|
| 6. | Cancrinite occurs in several nepheline-syenites.
|
| 7. | Bystrite has a structure that is shared with many of the minerals in the cancrinite group.
|
| 8. | It is associated with other minerals typical of undersaturated environments, namely leucite, cancrinite and natrolite.
|
| 9. | Nepheline is very abundant and there is also cancrinite, sodalite, scapolite, calcite, biotite and hornblende.
|
| 10. | In high temperature, sodalite would transform to cancrinite of which twelve-ring channels cage prefer bigger cation.
