Here are the mineral names or families/classes for the minerals you listed:
- Pyroxene: A group of silicate minerals known as the pyroxene group.
- Pyrite: A sulfide mineral, often referred to as "fool's gold."
- Dioptase: A mineral in the copper silicate group, specifically a cyclosilicate.
- Hematite: An oxide mineral, specifically a form of iron oxide.
- Magnetite: An oxide mineral, specifically a form of iron oxide and the primary ore of iron.
- 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.
