Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
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
Lherzolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

All about Lherzolite and Hyaloclastite Properties
Know all about Lherzolite and Hyaloclastite properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite and Hyaloclastite belong to Igneous Rocks.Texture of Lherzolite is Grenue whereas that of Hyaloclastite is Pyroclastic. Lherzolite appears Glassy, Vesicular and Foilated and Hyaloclastite appears Dull. The luster of Lherzolite is subvitreous to dull while that of Hyaloclastite is dull and grainy. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Hyaloclastite is available in brown, grey, yellow colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums and that of Hyaloclastite are cemetery markers, creating artwork.
