Formation
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
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 Shonkinite and Diatomite
Here you can know more about Shonkinite and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shonkinite and Diatomite consists of mineral content and compound content. The mineral content of Shonkinite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz 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 Shonkinite vs Diatomite, the texture, color and appearance plays an important role in determining the type of rock. Shonkinite is available in brown, buff, cream, green, grey, pink, white colors whereas, Diatomite is available in grey, white, yellow colors. Appearance of Shonkinite is Banded and Foilated and that of Diatomite is Soft. Properties of rock is another aspect for Shonkinite vs Diatomite. The hardness of Shonkinite is 5.5-6 and that of Diatomite is 1. The types of Shonkinite are Not Available whereas types of Diatomite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shonkinite and Diatomite is white. The specific heat capacity of Shonkinite is 0.92 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.Shonkinite is heat resistant, impact resistant, wear resistant whereas Diatomite is heat resistant.
