Part 2: Naming the Minerals
Name the minerals in the table below. Then, insert a percentage of how certain you are in your identification. Finally, explain your percentage of
certainty: What was confusing about this mineral? What other minerals do you think it could be?
Note. Be specific regarding the test you performed and the results, even if you are 100% certain of the mineral’s identification.
Remember, the minerals in the virtual lab include seven of the following: borax, calcite, corundum, graphite, gypsum, orthoclase feldspar, pyrite,
quartz, talc, and topaz.

Identification of mineral
Example: Fluorite
Percent certain
Explanation of certainty
80% certain
I am almost certain this mineral is fluorite, but I am not completely
sure. Fluorite and gypsum are both white, shiny, have white streaks,
cleave, and show no reaction to acid. However, the specific gravity of
this mineral is 3.18, which is higher than gypsum, so I am pretty sure
it is fluorite.
