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

Formation
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.
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.

More about Diatomite and Adamellite
Here you can know more about Diatomite and Adamellite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Adamellite consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Adamellite includes Apatite, Biotite, Chlorite, Orthoclase, Perthite, Plagioclase, Quartz, Titanite, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Adamellite, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Adamellite is available in black, grey, orange, pink, white colors. Appearance of Diatomite is Soft and that of Adamellite is Veined or Pebbled. Properties of rock is another aspect for Diatomite vs Adamellite. The hardness of Diatomite is 1 and that of Adamellite is 6-7. The types of Diatomite are Not Available whereas types of Adamellite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diatomite and Adamellite is white. The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Adamellite 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.Diatomite is heat resistant whereas Adamellite is heat resistant, wear resistant.
