    The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having nearly perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms. Mica is used in a variety of products ranging from drywalls, paints, fillers, especially in parts for automobi

    DescriptionRelation to MiningUsesMica 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. There are 37 different mica minerals. The most common include: purple lepidolite, black biotite, brown phlogoSee more on mineralseducationcoalition

    Mica, any of a group of hydrous potassium, aluminum silicate minerals. It is a type of phyllosilicate, exhibiting a two-dimensional sheet or layer structure. Among the principal rock-forming minerals, micas are found in all three major rock varieties—igneous, sedimentary, and metamorphic.

  • The Interesting Properties and Common Uses of the Mineral Mica

    A mineral is an inorganic solid found in nature. It has a specific chemical formula, and is crystalline in structure. Mica is one such mineral, and it is a silicate mineral. It has traces of metals like potassium, iron, aluminum, and magnesium. It also has some water content in it. Rock-forming mica (other than glauconite) can be divided into 2

  • Learn About the Minerals Known As Mica ThoughtCo

    The mica minerals are distinguished by their perfect basal cleavage, which means that they are easily split into thin, often transparent, sheets. Two micas, biotite, and muscovite, are so common that they are considered rock-forming minerals. The rest are relatively uncommon, but phlogopite is the most likely of these to be seen in the field.
