Mica is one of the non-metallic minerals and is used in the construction, chemical, electrical, and manufacturing industries. It was first discovered and mined in Canada in the 19 th century, with many important mines operating within a 150-mile radius of Ottawa. There are several types of mica, and this specimen is phlogopite mica.

The mica group comprises 34 silicate minerals that have a layered or platy texture; large flakes and sheets are found in some metamorphic and igneous rocks. The commercially important micas are muscovite and phlogopite. Mica is stable when exposed to electricity, light, moisture, and extreme temperatures.

Of the 28 known species of the mica group, only 6 are common rock-forming minerals. Muscovite, the common light-coloured mica, and biotite, which is typically black or nearly so, are the most abundant. Phlogopite, typically brown, and paragonite, which is macroscopically indistinguishable from muscovite, also are fairly common.
