“chlorite”的概念、定义、翻译、参考文献-科学参考

chlorite

Chemistry

1. See chlorates.
2. A group of layered silicate minerals, usually green or white in colour, that are similar to the micas in structure and crystallize in the monoclinic system. Chlorites are composed of complex silicates of aluminium, magnesium, and iron in combination with water, with the formula (Mg,Al,Fe)₁₂(Si,Al)₈O₂₀(OH)₁₆. They are most common in low-grade metamorphic rocks and also occur as secondary minerals in igneous rocks as alteration products of pyroxenes, amphiboles, and micas. The term is derived from chloros, the Greek word for green.

Geology and Earth Sciences

Important group of phyllosilicate (sheet silicate) minerals with the general composition (Mg,Fe,Al)₆[(SiAl)₄O₁₀](OH)₈ and related to the micas; sp. gr. 2.6–3.3; soft and green; platy or tabular habit; occur in low-grade metamorphic rocks of greenschist facies and as an alteration product of ferromagnesian minerals in igneous rocks. The group includes specific minerals, e.g. clinochlore, delessite, penninite, and thuringite. Chamosite and greenalite are septichlorites which are chemically similar to the chlorites.
