The following tests can determine the mineral in a rock specimen:

1. How does the rock crumble or split under pressure?

2. What is the texture of the rock?

3. Observing it under a magnifying lens.

4. Determine the color of the rock



Test 1 and 3 determines if the rock is granular and the types of grains in the rock. Test 3 also determines if the rock has layers hence sedimentary rock.

Determining whether color of the rock is dark or light also helps identify the mineral and type of rock.
