Types of forms occurring in rock minerals

1. Tabular Form- In this type of form , minerals appears as slabs of uniform thickness e.g. Feldspar.

2. Lamellar Form –Minerals appears as thin separable layers e.g. Vermiculite.

3. Fibrous Form- Minerals exists in the form of separable or non separable fine fibres e.g. Asbestos.

4. Bladed Form- Minerals are of rectangular lath shaped grains eg. Kyanite.

5. Granular Form- In this , minerals appears in the form of closely packed equal grains e.g. Chromite.

6. Reni Form- Minerals are available in the form of kidney shaped or sub rounded shape e.g Hematite.

7. Mamillary Form- Minerals appear with large matually interfering spheroidal surfaces e.g. Malachite.

8. Prismatic form – Minerals are of independent elongated crystals e.g. Quartz
