Question

Give the mineral name or family or class of the following minerals
1: pyroxene
2: pyrite
3: dioptase
4: hematite
5: magnetite
6: biotite
And give the specific clevage degree ot biotite and dioptase

Answer 1

Here are the mineral names or families/classes for the minerals you listed:

1. **Pyroxene**: A group of silicate minerals known as the pyroxene group.
2. **Pyrite**: A sulfide mineral, often referred to as "fool's gold."
3. **Dioptase**: A mineral in the copper silicate group, specifically a cyclosilicate.
4. **Hematite**: An oxide mineral, specifically a form of iron oxide.
5. **Magnetite**: An oxide mineral, specifically a form of iron oxide and the primary ore of iron.
6. **Biotite**: A member of the mica group, which is a phyllosilicate mineral.

### Cleavage Degrees:
- **Biotite**: Biotite has perfect cleavage in one direction (1 direction), which allows it to split into thin flexible sheets.
- **Dioptase**: Dioptase has imperfect cleavage in one direction, which means its cleavage is not as well-defined as that of biotite.
