Mineral Properties Roundup

The above figure is testing the mineral's-

• cleavage and fracture

• hardness and color

• luster and density

• streak and magnetism

Gavin conducted a mineral identification experiment with an unknown mineral. He found that the mineral looked black, had a black streak, would fracture, and was sub metallic. What mineral did Gavin most likely find?

• Bornite

• Magnetite

• Graphite

• Biotite

A student was given an unknown mineral sample and told the mineral's hardness is approximately 3. This sample could only be what two minerals?

• Bornite or Geothite

• Hematite or Geothite

• Biotite or Bornite

• Graphite or Biotite
