Etymology
From English clay and stone as the rock contains more amount of clay
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

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

More about Claystone and Lherzolite
Here you can know more about Claystone and Lherzolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Lherzolite consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Lherzolite, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. Appearance of Claystone is Rough and Dull and that of Lherzolite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Claystone vs Lherzolite. The hardness of Claystone is 3.5-4 and that of Lherzolite is 6.5. The types of Claystone are Claystone whereas types of Lherzolite are Garnet Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Lherzolite is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Lherzolite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant.
