Chlorite Group – WGNHS – UW–Madison
Chlorite represents a group of over 10 minerals related by complex solid solution substitutions. These minerals are generally fine-grained, micaceous and dark green. They are not easily distinguished except by sophisticated chemical and X-Ray analysis.

Light to dark green, grayish-green, black. Some rarer varieties are white, yellow, brown, pink and purple. Crystals are usually tabular and pseudohexagonal in shape, but also may be prismatic. Also as thick flakes, micaceous masses and groupings, and in foliated, flaky, and scaly forms. May also be massive and in globular masses of dense flakes.

2023年9月9日 · Color: Chlorite minerals can exhibit a range of colors, but they are most commonly green, varying from pale green to dark green. The green color is due to the presence of iron and other elements within the crystal structure.
Chlorite: Mineral description, properties and formation - Geology.com
Chlorite is the name of a group of common sheet silicate minerals that form during the early stages of metamorphism. Most chlorite minerals are green in color, have a foliated appearance, perfect cleavage, and an oily to soapy feel.

2024年5月18日 · Various green rocks derive their color from minerals like chlorite, actinolite, and epidote, but each type of rock has unique properties and origins. Green minerals such as glauconite and serpentine are commonly found in settings …
Chlorite group - Wikipedia
Chlorite is one of the most common minerals produced by propylitic alteration by hydrothermal systems, where it occurs in the "green rock" environment with epidote, actinolite, albite, hematite, and calcite.
Chlorite - Geology is the Way
Chlorite, like other phyllosilicates, forms platy crystals and flakes with a characteristic basal cleavage, commonly appearing greenish in color (although yellow, grey, or red chlorites do exist). It is less shiny than micas and tends to show a vitreous to dull luster.

·Color - generally pleochroic, ranging from colorless to pale to medium green. Sometimes darker green or (rare) other colors. ·Interference colors are distinctive: lower first order, and often anomalous. Anomalous blue, purple or brown are quite common. ·Cleavage - chlorite may show a single good cleavage.
Chlorite metamorphic mineral - James Madison University
Chlorite is a light to dark green or black, pearly luster mineral with perfect basal cleavage. Forms thin, flexible flakes that can be peeled off with a fingernail. In this specimen a mass of crystals with pearly luster crystals and basal cleavage can be easily seen.
