How is phyllite formed
WebPhyllite’s composition is quartz, muscovite and chlorite: essentially it’s slate that has been subjected to a longer period of metamorphosis. Slate was formed as a result of fine-grained, shale-type sediments being deposited deep on the ocean floor, the thick beds slowly compressing to form a layered sedimentary rock. WebAs the process of metamorphism continues, additional pressure and temperature will cause the minerals to continue to recrystallize and become larger. The next stage in this transition will be the formation of a phyllite, which has slightly larger (but still microscopic) mica crystals than the slate.

WebWhere slate is typically planar, phyllite can form in wavy layers. In the formation of schist, the temperature has been hot enough so that individual mica crystals are visible, and … WebWhen it is formed from a limestone with very few impurities, it will be white in color. Marble that contains impurities such as clay minerals, iron oxides, or bituminous material can be bluish, gray, pink, yellow, or black in color. Marble of extremely high purity with a bright white color is very useful.
WebPhyllite is a fine-grained metamorphic rock formed from sedimentary rocks, such as shale and mudstone. A metamorphic rock is created when existing rock is physically and chemically transformed by intense heat and pressure. Phyllite is metamorphosed from shale, its protolith or parent rock. WebThe phyllite forms from pelitic sediments (shale and mudstone) at a slightly higher degree of regional metamorphism from slate ( Table 7.1 ). It may also originate from finely grained tuffs and clayey tuffite.
