- Each Chart lists or groups minerals according to their properties. For example, on the Color Chart (part of which is shown on the right), minerals are grouped by color. If a mineral may have more than one color, its name will appear in more than one place on the Chart. (See, for example, quartz - circled in red.)
- WORKED OUT EXAMPLE TO DEMONSTRATE PROCEDURE:
- The following properties have been determined for Sample # 1:
- COLOR: white
- HARDNESS: hard, Mohs value 6
- MISCELLANEOUS VISUAL PROPERTIES: striations
- Examination of the Color Chart shows that the following minerals may be white: albite, kaolin, calcite, gypsum, halite, quartz
- Examination of the Hardness Chart shows that the following minerals may have a hardness of 6: magnetite, albite, orthoclase, labradorite
- Examination of the Miscellaneous Visual Properties Table shows that the following minerals may have striations: albite, labradorite, pyrite.
- Examination of the three lists of minerals shows that only Albite - outlined in blue - is common to all three lists.
- Record the mineral name, Albite, in the indicated place on Part B of your printout of the Mineral Identification Form.
- When you have matched your sample numbers to mineral names, record the names in the indicated places on Part B of your printout of the Mineral Identification Form.
