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

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
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.

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