Archaeological Significance
Formation
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
