Used as a filler and as a constituent of clay. (~9.6 centimeters across at its widest) Metamorphic rocks result from intense alteration of any previously existing rocks by heat and/or pressure and/or chemical change.

Streak of rock is the color of powder produced when it is dragged across an unweathered surface. Chlorite schist exhibits velocity‐strengthening behavior, epidotite is velocity‐weakening, and the amphibolite shows mostly velocity‐weakening friction. Within ultramafic rocks, metamorphism also can produce predominantly clinochlore chlorite in affiliation with talc. en-hi. Another source points out the predominance of mica-quartz-chlorite schist, a green-hued metamorphosed shale, as a possible reason. Cubic rock samples (15 mm × 15 mm × 15 mm) were cut from larger rocks and subjected to time‐compressed climatic conditions simulating the tropical wet season climate at the Ranger Uranium Mine in the Northern Territory, Australia. However, the time period Chlorite may be used each to explain the organization in fashionable, or as a specific term to explain any inexperienced member of the Chlorite institution whose precise identity isn’t always realistic to be decided.
