If you ever wanted to know which Rock Type a mineral comes from - i.e. Igneous, Sedimentary, and Metamorphic, you had to look at the environment field and try to figure this out. We just made this much easier by adding a new field called "Rock Type" for every mineral in our database. Every mineral will now show a new field displaying which of the major three rock types the mineral occurs in. We had to create the new field and manually enter in the correct data for each mineral.
