Identification key
A mineral identification key is a chart that will give information about the properties of the minerals listed on the key. Properties of a given mineral are compared to those listed on the key and the mineral can be identified. Some common minerals with very observable properties include calcite, feldspar, mica, talc, gypsum, quartz, and fluorite.
