由泥岩、貢岩或凝灰岩等細顆粒岩石經區域變質作用而成，若母岩為砂岩，則通常變質成石英雲母片岩，甚至石英片岩。

Living Specimens: (Fossil)
Fine-grained rocks such as mudstone, tribute rock or tuff are formed by regional metamorphism. If the parent rock is sandstone, it is usually metamorphosed into quartz mica schist and even quartz schist.

有明顯片理構造，主要由雲母類等片狀礦物平行排列而形成，片理常呈波浪狀的灣曲構造，顏色受所含雲母形響。因雲母含量高，常呈絹絲光澤，常順著解面剝離。

深灰色。

There are obvious schistosomiasis structures, mainly formed by the parallel arrangement of flaky minerals such as mica. The schistosity is often a wavy bay curved structure, and the color is affected by the mica-like structure. Due to high mica content, often was silk luster, often along the solution surface peel.

Dark gray

可作藥材、防火燃料、橡膠工業及電子與電器工業。絹雲母片岩可用來製備的汽車缸墊用岩粉，或用來製造汽車用離合器片、制動系統、砂輪片等耐摩擦產品，雲母片岩之碎塊可當作藥材，稱為金礞石，據稱可治療頑痰難咯、咳喘日久痰多等病症或熱性痰積引起的驚悸、癲癇等症。另外雲母片岩含大量白雲母及絹雲母，是橡膠工業中常用的無機填料，亦是一種新類、實用、優質多功能塗料，能防止紫外線的穿透而改善塗膜的耐候性，可當電子與電器工業中熱和電的絕緣體。絹雲母粉用於電焊條製造，可提高壓塗性能，能降低成本，並可替代石棉成為防火材料，用絹雲母製作鑽井泥漿，在堵塞孔隙、裂隙，防止泥漿漏失的過程中效果顯著，亦是製紙、塑膠工業之重要原料。另外，雲母片岩中有時可發現綠柱石或石榴子石礦。

Can be used as herbs, fire fuels, rubber industry and electronics and electrical appliances industry. Sericite schist can be used to prepare the car cylinder pad with rock dust, or used in the manufacture of automotive clutch plates, brake systems, grinding wheel and other friction products, fragments of mica schist can be used as herbs, known as the gold stone, according to Said stubborn phlegm can be difficult to treat cough, cough and other phlegm and other diseases or heat caused by phlegm product fritter, epilepsy embolism. In addition mica schist contains a large number of muscovite mica and sericite, the rubber industry is commonly used inorganic fillers, is also a new class of practical, high-quality multi-functional coatings to prevent UV penetration and improve the weather resistance of the coating, Thermal and electrical insulators in the electrical industry. Sericite powder used in the manufacture of welding electrodes, can improve the coating properties, can reduce costs, and can replace asbestos as a fireproof material, making drilling mud with sericite, in blocking the pores, cracks, to prevent leakage of mud in the process of significant effect, but also It is an important raw material for papermaking and plastics industry. In addition, beryl or garnetite are sometimes found in mica schist.
