Chlorites are a group of minerals that belong to the phyllosilicate family, characterized by their layered structure. They typically contain magnesium, iron, and aluminum, along with hydroxyl groups. Chlorites are often green in color and can be found in various geological environments, including metamorphic rocks and as alteration products of other minerals. These minerals are commonly associated with mica and serpentine and can be used as indicators of metamorphic conditions. Chlorites are also important in the study of geology and petrology, as they provide insights into the history and formation of rocks.
