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.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

More about Diatomite and Basanite
Here you can know more about Diatomite and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Basanite consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Basanite , the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Diatomite is Soft and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Diatomite vs Basanite . The hardness of Diatomite is 1 and that of Basanite is 7. The types of Diatomite are Not Available whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diatomite and Basanite is white. The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Basanite is 0.74 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 Basanite is heat resistant, impact resistant, pressure resistant, wear resistant.
