Definition
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions

Etymology
From Pelos or clay in Greek
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
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

Metapelite vs Lherzolite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Metapelite vs Lherzolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Metapelite and Properties of Lherzolite. Learn more about Metapelite vs Lherzolite in the next section. The interior uses of Metapelite include Decorative aggregates and Interior decoration whereas the interior uses of Lherzolite include Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Metapelite and Lherzolite, they have various applications in construction industry.

More about Metapelite and Lherzolite
Here you can know more about Metapelite and Lherzolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Lherzolite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Lherzolite, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. Appearance of Metapelite is Banded and that of Lherzolite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Metapelite vs Lherzolite. The hardness of Metapelite is 5-6 and that of Lherzolite is 6.5. The types of Metapelite are Metamorphic rock 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 Metapelite is while that of Lherzolite is white. The specific heat capacity of Metapelite is 0.72 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.Metapelite is heat resistant, impact resistant, pressure resistant whereas Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant.
