Archaeological Significance
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.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

More about Diatomite and Gabbro
Here you can know more about Diatomite and Gabbro. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Gabbro consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Gabbro includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Gabbro, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Gabbro is available in dark grey to black colors. Appearance of Diatomite is Soft and that of Gabbro is Veined and Shiny. Properties of rock is another aspect for Diatomite vs Gabbro. The hardness of Diatomite is 1 and that of Gabbro is 7. The types of Diatomite are Diatomite whereas types of Gabbro are Anorthosite Gabbro and Norite Gabbro. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diatomite is white while that of Gabbro is black. The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Gabbro is 0.71 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 Gabbro is impact resistant, pressure resistant, wear resistant.
