Diatomite and Eclogite


Definition

Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature   
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth

Formation

Formation
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.   
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.

All about Eclogite and Diatomite Properties

Know all about Eclogite and Diatomite properties here. All properties of rocks are important as they define the type of rock and its application. Eclogite belongs to Metamorphic Rocks while Diatomite belongs to Sedimentary Rocks.Texture of Eclogite is Earthy whereas that of Diatomite is Clastic or Non-Clastic. Eclogite appears Dull, Banded and Foilated and Diatomite appears Soft. The luster of Eclogite is subvitreous to dull while that of Diatomite is dull. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas Diatomite is available in grey, white, yellow colors. The commercial uses of Eclogite are creating artwork, gemstone and that of Diatomite are alumina refineries, animal feed filler, as a feed additive for livestock, creating artwork, drawing on blackboards, fire resistant, gymnasts, athletes and mountain climbers use for grip, in aquifers, soil conditioner, to ignite fire, used as a filter medium, used as an insecticide, whiting material in toothpaste, paint and paper.
