Chlorite pseudomorph after garnet from Michigan (size: 3.5 × 3.1 × 2.7 cm) Experiments indicate that chlorite can be stable in peridotite of the Earth's mantle above the ocean lithosphere carried down by subduction , and chlorite may even be present in the mantle volume from which island arc magmas are generated.
7 Si 8 O 22 (OH) 2 for magnesiocummingtonite to the iron rich grunerite endmember Fe 7 Si 8 O 22 (OH) 2. Cummingtonite is used to describe minerals of this formula with between 30 and 70 per cent Fe 7 Si 8 O 22 (OH) 2. Thus, cummingtonite is the series intermediate. Manganese also substitutes for (Fe,Mg) within
