Definition of mica in English:

mica

noun ˈmʌɪkəˈmaɪkə

mass noun

A shiny silicate mineral with a layered structure, found as minute scales in granite and other rocks, or as crystals. It is used as a thermal or electrical insulator.
Example sentencesExamples
- The foliation is marked by chloritc, white mica and minute quartz grains.
- This partial drying could remove some of the water layer between mica and the bilayer, increasing the electrostatic repulsion between the substrate and lipid.
- The next most common minerals are silicates, such as mica, feldspar, pyroxene, and the olivines, which break down to clay, the soluble elements they contain being mostly carried away in solution.
- After the death of these organisms, radioactive carbon in the soft tissues of the organisms was converted into a film of mica and silicates, creating a stain in the rock layer.
- The mineral assemblage comprises quartz, K-feldspar, albitic plagioclase, white mica, apatite, tourmaline and garnet.

Derivatives

micaceous

adjective mɪˈkeɪʃəsmaɪˈkeɪʃəs

It is dominated at the exposure by angular quartzite clasts up to 40 cm long with subordinate, subroundcd sandy dolomite, angular micaceous siltstone and limestone clasts.
Example sentencesExamples
- I have always regarded specular hematite as a micaceous or platy form that would be very difficult to fashion into beads.
- These crystals were abundant in a very micaceous pegmatitic rock composed of muscovite, albite, and quartz with accessory schorl crystals.
- Some of the material contained micaceous masses of specular hematite associated with quartz, epidote, and numerous veinlets of calcite.
- Impressive blades and masses of lustrous micaceous hematite occur in localized quartz veins, and reniform goethite is found in the walls.

Origin

Early 18th century: from Latin, literally 'crumb'.

Rhymes

balalaika, biker, duiker, Formica, hiker, pica, pika, piker, striker
