To help you categorize items based on their characteristics, here are some general distinctions between fracture and cleavage that may assist:
Fracture: This refers to the way a mineral breaks unevenly, producing rough or jagged surfaces. Examples of items that exhibit fracture include:
- Quartz
- Obsidian
- Granite
Cleavage: This is when a mineral breaks along smooth, flat planes. Examples of items that exhibit cleavage include:
- Mica
- Halite
- Calcite
You can categorize the specific items you have based on these descriptions. If you have a list of items in mind that you need to classify, please provide them, and I can help you determine which category they belong to!
