The feldspathoids are not a typical mineral group like other mineral groups that are related by structure and chemistry. Their relation to each other is due primarily to their relationship to the feldspar group of minerals. Feldspathoids are low silica igneous minerals that would have formed feldspars if only more silica (SiO2) were present in the original magma.

Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.

Mica is the term for a large group of sheet silicates that can be parted into flexible or brittle sheets. Includes the True Micas or Common Micas (with monovalent interlayer cations, e.g. muscovite, paragonite, ephesite) and the Brittle Micas (with divalent interlayer cations, e.g. margarite, clintonite).Also known as the "mica family".
