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

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