Is chlorite foliated
WebPhyllite is a foliated, fine-grained metamorphic rock with slaty or weakly schistose texture. It has a shiny luster and its crystals may or may not be large enough to see with the naked eye. It is typically gray, green, black, brown, or red. Phyllite is formed from clay-rich shales or mudstones when slate undergoes further metamorphism. WebStrongly foliated glaucophane schist showing thin tabular glaucophane porphyroblasts (blueish, olive to pinkish-violet pleochroism), formed during blueschist facies metamorphism. Colorless lenses are dolomite. Dark-brown to black spots consist of titanite, green crystals are chlorite. Thin section, transmitted plane polarized light digital ...
