Archaeological Significance
Formation
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
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 Whiteschist and Diatomite
Here you can know more about Whiteschist and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Diatomite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Diatomite, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in green, grey, white colors whereas, Diatomite is available in grey, white, yellow colors. Appearance of Whiteschist is Banded and Foilated and that of Diatomite is Soft. Properties of rock is another aspect for Whiteschist vs Diatomite. The hardness of Whiteschist is 1.5 and that of Diatomite is 1. The types of Whiteschist are - 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 Whiteschist and Diatomite is white. The specific heat capacity of Whiteschist 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.Whiteschist is heat resistant whereas Diatomite is heat resistant.
