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
Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows

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.
Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.

More about Adamellite and Ignimbrite
Here you can know more about Adamellite and Ignimbrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adamellite and Ignimbrite 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 Ignimbrite includes Apatite, Biotite, Calcite, Chlorite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Adamellite vs Ignimbrite, 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, Ignimbrite is available in beige, black, brown, grey, pink, white colors. Appearance of Adamellite is Veined or Pebbled and that of Ignimbrite is Dull, Vesicular and Foilated. Properties of rock is another aspect for Adamellite vs Ignimbrite. The hardness of Adamellite is 6-7 and that of Ignimbrite is 4-6. The types of Adamellite are Granite whereas types of Ignimbrite are Pyroclastic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adamellite and Ignimbrite is white. The specific heat capacity of Adamellite is 0.79 kJ/Kg K and that of Ignimbrite is 0.20 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 Ignimbrite is heat resistant, impact resistant, pressure resistant, wear resistant.
