Chlorite minerals also form during the hydrothermal, metasomatic, or contact metamorphism.
| Physical Properties of Chlorite | |
|---|---|
| Chemical Classification | Silicate |
| Streak | Greenish to greenish gray |
| Luster | Vitreous, pearly, dull |
| Diaphaneity | Transparent, translucent, opaque |
In this manner, how do you tell if a metamorphic rock is foliated or Nonfoliated?
Foliated metamorphic rocks such as gneiss, phyllite, schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Non-foliated metamorphic rocks such as hornfels, marble, quartzite and novaculite do not have a layered or banded appearance.
Also know, is chlorite a non expanding clay?
The negative charge of chlorites is less than smectite or vermiculites but about the same as that of fine grained mica. There is no water adsorption between the layers responsible for the non – expanding nature of this crystal.
What does foliated and Nonfoliated mean?
Metamorphic rocks are broadly classified as foliated or non-foliated. Non-foliated metamorphic rocks do not have aligned mineral crystals. Non-foliated rocks form when pressure is uniform, or near the surface where pressure is very low.
What is chlorate and chlorite?
Chlorates are chemical compounds containing the anion having the formula ClO3–. In these compounds, chlorine atom is in the +5 oxidation state. Chlorite is a compound that contains the chlorine dioxide anion (ClO2–), with chlorine in the +3 oxidation state. … Chlorites are salts of chlorous acid.
What is chlorite made of?
Sodium chlorite — also referred to as chlorous acid, sodium salt textone, and Miracle Mineral Solution — is composed of sodium (Na), chlorine (Cl), and oxygen (O2).
What is chlorite rock?
Chlorite is a member of the mica group of minerals (sheet silicates), like biotite and muscovite. Chlorite is widespread in low grade metamorphic rocks such as slate and schist, in sedimentary rocks, and as a weathering product of any rocks that are low in silica (especially igneous rocks).

What is the importance of chlorite?
Chlorites characteristically occur as alteration products of other minerals. They are common rock-forming minerals in clastic sediments and in hydrothermally altered igneous rocks; chlorites are widespread and important constituents of such metamorphic rocks as greenschists or chlorite schists.
What is the use of chlorite?
Chlorite and chlorate are disinfection by-products resulting from the use of chlorine dioxide as a disinfectant and for odour/taste control in water. Chlorine dioxide is also used as a bleaching agent for cellulose, paper pulp, flour and oils and for cleaning and detanning leather.
