⦁Describe in your own words the 4 step process for mineral identification
⦁ STEP 1:
⦁ STEP 2:
⦁ STEP 3:
⦁ STEP 4:
⦁ Using the separately provided Mineral Identification Key, identify 18 minerals which are non-silicates (i.e. those minerals which lack silicon (Si) as part of their chemical composition) and identify whether each mineral is a native element, sulfide, oxide, hydroxide, halide, sulfate, carbonate, or phosphate (i.e. the chemical class of the mineral). Two minerals are done for you as examples.

⦁ Using the separately provided Mineral Identification Key, supporting mineral identification lab, and online resources, complete the following table by supplying: 1) the non-silicate mineral ID (taken from your responses to question #10), 2) properties of the mineral that would allow you to identify that mineral, and 3) an image of the mineral collected from an online resource. Two minerals are done for you as examples.
