| 1. | Kyanite in metamorphic rocks generally indicates pressures higher than four kilobars.
|
| 2. | In kyanite, this anisotropism can be considered an identifying characteristic.
|
| 3. | Kyanite is also known as disthene, rhaeticite and cyanite.
|
| 4. | By metamorphic isograd, the Main Central Thrust follows the kyanite isograd.
|
| 5. | Color varieties include recently discovered orange kyanite from Tanzania.
|
| 6. | Andalusite is trimorphic with kyanite and sillimanite, being the lower pressure mid temperature polymorph.
|
| 7. | It occurs as a secondary phase in pegmatites and kyanite ( aluminium-rich ) quartzites.
|
| 8. | Under this criterion, crystals of kyanite appear upward of several meters from the lithologic change.
|
| 9. | Kyanite is triclinic, while andalusite and sillimanite are both orthorhombic and belong to the dipyramidal point group.
|
| 10. | Bauxite, Kyanite, Marble, Dolomite, Clay and limestone are the other main minerals of the district.
