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
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks

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.
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

More about Adamellite and Phyllite
Here you can know more about Adamellite and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adamellite and Phyllite 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 Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Adamellite vs Phyllite, 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, Phyllite is available in black to grey, light greenish grey colors. Appearance of Adamellite is Veined or Pebbled and that of Phyllite is Crinkled or Wavy. Properties of rock is another aspect for Adamellite vs Phyllite. The hardness of Adamellite is 6-7 and that of Phyllite is 1-2. The types of Adamellite are Granite whereas types of Phyllite are Phyllite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adamellite and Phyllite is white. The specific heat capacity of Adamellite is 0.79 kJ/Kg K and that of Phyllite is 0.79 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 Phyllite is heat resistant, pressure resistant, water resistant.
