Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment

Formation
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

All about Carbonatite and Hyaloclastite Properties
Know all about Carbonatite and Hyaloclastite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite and Hyaloclastite belong to Igneous Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Hyaloclastite is Pyroclastic. Carbonatite appears Dull, Banded and Foilated and Hyaloclastite appears Dull. The luster of Carbonatite is subvitreous to dull while that of Hyaloclastite is dull and grainy. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas Hyaloclastite is available in brown, grey, yellow colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Hyaloclastite are cemetery markers, creating artwork.
