Sugilite is a rare mineral and a gemstone best known for its vibrant pink to purple color. Illite is the only common mineral. Sometimes a mix. Within ultramafic rocks, metamorphism can also produce predominantly clinochlore chlorite in association Chlorites have a silicate layer structure similar to that in micas with compositions near (Mg,Fe,Al) 3 (Si,Al) 4 O 10 (OH) 2 and with brucitelike interlayers with … This site has been providing detailed information and photos of hundreds of mineral and gemstone since 1997 and is one of the leading education resources on minerals and gemstones. From: Introduction to Mineralogy and Petrology, 2014 Below is a simple formula encompassing the common members of the Chlorite Group: Light to dark green, grayish-green, black. © Copyright 1997 - 2020 Hershel Friedman and Minerals.net, all rights reserved. Specimen is approximately 4 inches (10 centimeters) across. May also contain small amounts of chromium. The 2:1 layers are formed by the stacking of 2 sheets of tetrahedrally-coordinated silica, and one sheet of octahedraly coordinated Mg, Fe, or Al between the two tetrahedral sheets, as in micas or … Chlorites are 2:1:1 phyllosilicates minerals. Maderanertal, in Uri, Switzerland,  is famous for its shiny green Chlorite coatings on. Some chlorite like sodium chlorite is a strong base and is basically bleach. If you are requesting a locality be added, please only include. Chlorite-group minerals. Chamosite is a member of the Chlorite, and it forms a series with the mineral Clinochlore. Vanadinite.

The chlorites are a group of phyllosilicate minerals. Chakras: Related to the Heart Chakra. 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). It most often is an uninteresting matrix for more important minerals, but the rare and beautiful pink to red variety Kammererite is very popular and treasured by collectors. Chlorine is present in small amounts in many minerals. Chlorite group mostly contains Mg 2+, Al 3+, Fe 2+, Fe 3+, and some more chlorites Mn 2+, Cr 3+, Ni 2+, V 3+, Zn 2+ and Li +.

Commonly found as plates or scales similar to the micas. Astrological signs: Corresponds to Sagittarius. They have a structure that resembles that of micas or vermiculites, but with an additional layer of octahedrally-coordinated Mg, Al or Fe in the interlayer space. Fe-rich chlorite will appear blue, often called “anomalous blue” or “Berlin blue.” δ: 0.006 to 0.020: Special properties: Chlorite is a common alteration mineral which often retains the habit of the original mineral. They are also found as retrograde minerals in igneous and metamorphic rocks that have been weathered. Our Recommended Book Selection at Amazon.com, Financial Donations and Collection Acquisitions. Basic iron magnesium aluminum silicate. The stability of pure smectite minerals is typically restricted to the uppermost 3–4 km of the upper crust (Huang et al., 1993). The Mineral cookeite Cookeite (pronounced Cook-ite) is an uncommon member of the Chlorite group, and is best known for its occurrence in granite pegmatite s associated with Tourmaline, where it often forms as a growth layer upon the Tourmaline. We strive for accurate content and locality information. Chlorite is also a common metamorphic mineral, usually indicative of low-grade metamorphism. A group of mostly monoclinic (also triclinic or orthorhombic) micaceous phyllosilicate minerals with a structure consisting of T-O-T layers with two layers having their silicate tetrahedral apices pointing towards each other, separated by an interlayer that may be simple octahedrally coordinated cations or which may be a brucite-*like* layer of two sheets of closely packed OH groups with the interstices … Some rarer varieties are white, yellow, brown, pink and purple.
