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
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth

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.
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

More about Adamellite and Diatomite
Here you can know more about Adamellite and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adamellite and Diatomite 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 Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Adamellite vs Diatomite, 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, Diatomite is available in grey, white, yellow colors. Appearance of Adamellite is Veined or Pebbled and that of Diatomite is Soft. Properties of rock is another aspect for Adamellite vs Diatomite. The hardness of Adamellite is 6-7 and that of Diatomite is 1. The types of Adamellite are Granite whereas types of Diatomite are Diatomite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adamellite and Diatomite is white. The specific heat capacity of Adamellite is 0.79 kJ/Kg K and that of Diatomite is 0.90 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 Diatomite is heat resistant.
