D. a rock with metamorphic minerals but no foliation or lineation. A shale is metamorphosed into three rock types: (1) a banded gneissic rock; (2) a rock with small mica crystals with a shiny aspect; (3) a very shiny rock with large mica crystals; and (4) a dull slate with cleavage. Which of the following lists these rocks in order of increasing metamorphic grade?
Although the green colors of tsavorite and demantoid overlap, they are different garnet group minerals. Tsavorite is green grossular and demantoid is green andradite. Andradite is softer than grossular but has a higher refractive index and higher dispersion.lthough the green colors of tsavorite and demantoid overlap, they are different garnet group minerals.
