Physical properties used for identifying a mineral

Physical properties used for identifying a mineral This site has a separate page for each of the most useful physical properties for identifying a mineral. Although some of these properties can be measured precisely (e.g. specific gravity), they are more commonly used qualitatively to identify minerals in the field, where no sophisticated equipment is available.

Chemical Properties of Minerals

The chemical formula of the mineral Hematite is Fe 2 O 3. The letters describe the element type (Fe = iron, O = oxygen), and the subscripted numbers describe the amount of those atoms in each molecule. A Hematite molecule has 2 iron (Fe) atoms and 3 oxygen (O) atoms.

The mineralogy of Iron

Higher concentrations in pyrope garnet cause a deeper red colour. Fe 3+ in octahedral sites. When the Fe 3+ ions are isolated by intervening ions it leads to a pale colour, such as the pale purple colour in strengite and coquimbite. Also the yellow-green colour in ferric silicates such as andradite.
