What is the significance of the color of a mineral's streak in identifying a feldspar?
What is the significance of the color of a mineral's streak in identifying a feldspar?
The streak color can help differentiate between different feldspar varieties. For instance, an orange streak indicates Oligoclase.
When identifying a metallic mineral, observing the _______ color after breaking the specimen can provide valuable information.

Study Notes
Identifying Minerals
- Non-Metallic Minerals:
- Test for acidity
- Test hardness
- Test streak
- Observe cleavage/fracture
- Observe luster
- Look for associated minerals
- Feldspar Minerals:
- If white, look for associated minerals (low Bowen's):
- Albite
- If orange streak, Oligoclase
- If labradorescence, Labradorite
- If yellow/translucent, Bytownite
- If grey/dark, associated with top Bowen's, Anorthite
- If white, look for associated minerals (low Bowen's):
- Metallic Minerals:
- Check for magnetism
- Test hardness
- Test streak
- Observe oxidation color at break
- Check specimen
- Look for associated minerals
