Types of minerals Types of minerals , Muscovite mica, biotite mica, clay minerals; Framework silicat eg Quartz, feldspars, zeolites; Identification Identifying common minerals can usually be accomplished by examining a hand specimen Minerals have distinct physical properties such as specific gravity, streak, and form which can easily .
Schist Schist is medium grade metamorphic rock, formed by the metamorphosis of mudstone / shale, or some types of igneous rock, to a higher degree than slate, ie it has been subjected to higher temperatures and pressurThe resulting foliation is coarser and more distinct than that of slate due to the higher degree of crystallisation of mica minerals ( biotite, chlorite, muscovite) forming .
Learning mineral identification is like learning to cook You begin by following step-by-step procedures and looking up a lot of things But after a while you notice regularities, become familiar with the usual suspects, make some productive mistakes, and get better at it until it becomes easy and fun
Muscovite is the most common mineral of the mica family It is an important rock-forming mineral present in igneous , metamorphic , and sedimentary rocks Like other micas it readily cleaves into thin transparent sheets

Mica is a mineral name given to a group of minerals that are physically and chemically similar They are all silicate minerals, known as sheet silicates because they form in distinct layers Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible
This type of emerald the Spanish miners called trapiche, which is a Spanish word for a type of gear wheel These emeralds are reported to be found in both the Muzo and Chivor mines of Colombia, These emeralds are reported to be found in both the Muzo and Chivor mines of Colombia.
Mica is a common rock-forming mineral, and is found mainly in igneous and metamorphic rock Mica is mined in the following areas: India, Brazil,The USA, Tanzania, Rhodesia and Argentina, Malagasy Republic, Tanzania Canada, India and The USSR
This distinctive mineral is easy to identify by its platy appearance Commonly seen as shiny flecks in sedimentary, igneous, or metamorphic rocks, mica easily flakes off into thin crystal plat Two common varieties of mica are muscovite (typically pale in color) and biotite (darker brown to black)

The Mineral Identification Key Cleavage refers to the way some minerals break along certain lines of weakness in their structure Mica is a good example – breaking along very closely spaced flat planes that yield thin "sheets"
The Mineral Identification Key Habit is the general appearance a mineral tends to have – whether it is found as blocky crystals, long slender ones, or aggregates of some type, etc If the crystals are glassy but cubic in shape you know they aren’t quartz

Minerals have some other properties that can be used to identify them For example, a mineral's crystal structure can be used to help identify the mineral Sometimes, a trained mineralogist can tell the crystal structure just by looking at the shape of the mineral
Mica minerals commonly occur as flakes, scales, or shreds Sheet muscovite (white) mica is used in electronic insulators, paints, as joint cement, as a dusting agent, in welldrilling mud and lubricants, and in plastics, roofing, rubber, and welding rods
