WebIn the biotite zone (~ 300–400 °C), biotite nucleates and grows as widely spaced, dark-colored porphyroblasts that give such schists a “spotted” appearance in hand specimen. This occurs via the same reaction noted previously for initial biotite porphyroblast growth in contact metamorphic aureoles. WebThis type of sandstone contains fewer grains made of quartz and more of feldspars, volcanic rock fragments ,as well as silt and clay than most sanstone.
