Definition
Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz
Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation

Archaeological Significance
Formation
Adamellite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma and is a variety of Monzogranite.
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

More about Adamellite and Schist
Here you can know more about Adamellite and Schist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adamellite and Schist consists of mineral content and compound content. The mineral content of Adamellite includes Apatite, Biotite, Chlorite, Orthoclase, Perthite, Plagioclase, Quartz, Titanite, Zircon and mineral content of Schist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc. You can also check out the list of all Igneous Rocks. When we have to compare Adamellite vs Schist, the texture, color and appearance plays an important role in determining the type of rock. Adamellite is available in black, grey, orange, pink, white colors whereas, Schist is available in black, blue, brown, dark brown, green, grey, silver colors. Appearance of Adamellite is Veined or Pebbled and that of Schist is Layered and Shiny. Properties of rock is another aspect for Adamellite vs Schist. The hardness of Adamellite is 6-7 and that of Schist is 3.5-4. The types of Adamellite are Granite whereas types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adamellite and Schist is white. The specific heat capacity of Adamellite is 0.79 kJ/Kg K and that of Schist is 0.70 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Adamellite is heat resistant, wear resistant whereas Schist is impact resistant, pressure resistant, water resistant.
