2024 2 6 Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (100 megapascals (1,000 bar) or more), causing profound physical or chemical protolith may be a sedimentary, igneous, or existing metamorphic

The most widespread green mineral, chlorite is rarely present by itself. In microscopic form, it gives a dull olive green color to a wide range of metamorphic rocks from slate and phyllite to schist. Although it appears to have a flaky structure like mica, chlorite gleams rather than sparkles and doesn't split into flexible sheets.
