Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Etymology
From the Lherz Massif, an alpine peridotite complex, at Étang de Lers, near Massat in the French Pyrenees; Lherz is the archaic spelling of this location

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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

All about Lherzolite and Claystone Properties
Know all about Lherzolite and Claystone properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite belongs to Igneous Rocks while Claystone belongs to Sedimentary Rocks.Texture of Lherzolite is Grenue whereas that of Claystone is Clastic. Lherzolite appears Glassy, Vesicular and Foilated and Claystone appears Rough and Dull. The luster of Lherzolite is subvitreous to dull while that of Claystone is dull. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums and that of Claystone are pottery.
