Luster
Hardness
Cleavage
Streak
A student finds an unknown substance while on a nature hike. He claims to have found a new, undiscovered mineral. Does the information he collected in his Field Notes and the information in the chart of KNOWN minerals below support or reject his claim? Students information- Streak black, color, brassy yellow, hardness 6.5, fractures, and luster is metallic.
Support his claim
Reject his claim
Insufficient information
