The cleavage of mica is perfect. Sometimes it has parallel parting. The cleavage laminae is flexible and elastic. The thin translucent sheets allow geologists to view the metamorphosis.
The micas are used as dielectrics.
What is pink color nonmetalic and galssy luster softer than topaz quuartz scratches apatite harder than fluorite has clevage and is scratched by a steel file?
sulfides, oxides, silicates (with many subcategories), carbonates, clays, micas. Those are the main ones I can think of.
Copper, gold, silver, molybdenite, quartz, feldspars, micas, amphibole, magnetite, tourmaline, epidote, diamond, garnets, and many others.
There is no broken parts in quartz, so Quartz does not have cleavage.
Micas are monoclinic.
Cynthia Micas is 165 cm.
Cynthia Micas was born on February 2, 1990, in Berlin, Germany.
oh yeah
frature
Conchoidal Fracture. Clevage is impossible in a pearl
a diamonds cleavage is the cleavage of a diamond
when u feel ready :)
it has a bad clevage.thank you.astalavista baby
Your question is unclear. Muscovite is not a group name, but there are a number of polytypes, as listed by Fleischer's Glossary, 2008: -2M1, -1M, , and -2M2. The micas are divided into three main subgroups: true micas, brittle micas, and interlayer-deficient micas. These total about 44 species. There are also six incompletely investigated micas that are now considered to be series.
phyllite is a type of metasedimentary rock. The parent rock likely contained clays and/or micas, which have metamorphosed into micas and aligned due to pressure. This shiny surface is produced by the alignment of the minerals.
The silicon-oxygen tetrahedral bonds in micas create a sheet structure with weak bonds between the sheets. This allows micas to cleave along these weak planes, resulting in their characteristic perfect basal cleavage.
