There are almost 40 different minerals in this group called micas, and their common characteristics are a) they are phyllosilicates, and b) they have perfect basal cleavage, and c) form monoclinic crystals.
In the hand sample they are glittery and some are coloured.
Have a crack at the article Micas in wikipedia.
What else can I help you with?
What are the crystals in slate?
The shiny crystals along which slate cleaves are made of mica.
Which metamorphic rock will have visible mica crystals and a foliated texture?
quartzite
What is the mineral with crystals that breaks into flat sheets?
Mica is crystalline and forms layers.
Would mica be consider a rock?
Mica is not considered a rock; it is a mineral that is commonly found in rocks. Mica is a group of silicate minerals that are known for their perfect cleavage, flexibility, and ability to split into thin sheets.
What are the names of songs with food in them?
Lollipop by Mica.
What is mica called once its formed intoa metamorphic form?
Mica.
What is mica shisht made of?
Mica schist is a metamorphic rock primarily composed of mica, quartz, and feldspar. It forms through the metamorphism of shale or clay-rich rocks under high temperature and pressure conditions. Mica schist typically has a foliated texture due to the alignment of mica crystals during metamorphism.
What is the most common form of minerals?
Minerals form into crystals or clusters of crystals. In the crust, the most common individual mineral is quartz, and the most common class of minerals are the silicate minerals.
What are the crystalline solids which form the cooling magma?
Crystalline solids that form as magma cools include minerals like quartz, feldspar, and mica. The specific minerals that form depend on the chemical composition and cooling rate of the magma. Slow cooling allows larger crystals to form, while rapid cooling results in smaller crystals or even an amorphous (non-crystalline) solid.
Can salts form crystals?
Yes. Salts can form crystals (salt crystals).
What is the size of crystals in granite?
Crystals in granite can vary in size, but typically range from 1 mm to several centimeters in diameter. The size of crystals is influenced by factors such as the rate of cooling of the magma and the mineral composition of the granite.
What is mineral crystals of quartz biotite mica and amphibole are produced primarily by?
Mineral crystals of quartz, biotite mica, and amphibole are primarily produced by the process of crystallization from a cooling magma or lava. As the molten rock cools and solidifies, these minerals crystallize out of the melt based on their individual chemical and physical properties, forming distinct mineral crystals.
