Many types of mica are known: biotite, lepidolite, muscovite, phlogopite, zinnwaldite, clintonite, illite, phengite.
Yes, it is, it is acually made up of 4 types of minerals, feldspar, quartz, mica, and hornblende
mica has the specific gravity of 2.88
The two main leaf types are simple and compound leaves. The main difference is in their surface areas and the shape edges.
The two main types of animals are vertebrates, and invertebrates. This is classified as animals with a back bone (vertebrates), and animals without a back bone (invertebrates).
Mica Is Not A Renewable Resource Because Think About When Muscovite Mica And Biotite Mica Go Extinct. Muscovite Mica And Biotite Mica Are Both Types To Make Mica, And If That Goes Extinct Then Mica Will Be Extinct Too.
Many types of mica are known: biotite, lepidolite, muscovite, phlogopite, zinnwaldite, clintonite, illite, phengite.
The various types of mica do not contain elements which are significantly radioactive, e.g. K, Al, Si, O, F, H, Mg. (Rare isotopes of several common elements are part of the normal background radiation and no excess of these is found in mica.) Of course, there is the possibility that at any given mining site there can be contamination from other sources, but that is true of anything. Some examples showing the elements in mica are given below. The mica group contains 37 different sheet silicate (phyllosilicate) minerals. The chemical formula for the various types is complicated. Here are two common examples. Common mica (also called Muscovite ) is KAl2(AlSi3O10)(F,OH)2, or (KF)2(Al2O3)3(SiO2)6(H2O). Magnesium mica (Phlogopite) has the chemical formula KMg3AlSi3O10(F,OH)2. There are many more forms in the mica group of 37 phyllosilicate minerals.
