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
Shonkinite is a rare, dark-coloured and intrusive igneous rock which contains augite and orthoclase feldspar as its primary constituents

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.
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

More about Adamellite and Shonkinite
Here you can know more about Adamellite and Shonkinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adamellite and Shonkinite 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 Shonkinite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Adamellite vs Shonkinite, 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, Shonkinite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Adamellite is Veined or Pebbled and that of Shonkinite is Banded and Foilated. Properties of rock is another aspect for Adamellite vs Shonkinite. The hardness of Adamellite is 6-7 and that of Shonkinite is 5.5-6. The types of Adamellite are Granite whereas types of Shonkinite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adamellite and Shonkinite is white. The specific heat capacity of Adamellite is 0.79 kJ/Kg K and that of Shonkinite is 0.92 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 Shonkinite is heat resistant, impact resistant, wear resistant.
