Definition
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions

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
Shoshonite 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 Shoshonite and Lherzolite
Here you can know more about Shoshonite and Lherzolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Lherzolite consists of mineral content and compound content. The mineral content of Shoshonite includes Pyroxene and mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite. You can also check out the list of all Igneous Rocks. When we have to compare Shoshonite vs Lherzolite, the texture, color and appearance plays an important role in determining the type of rock. Shoshonite is available in brown- black, dark brown colors whereas, Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. Appearance of Shoshonite is Dull and that of Lherzolite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Shoshonite vs Lherzolite. The hardness of Shoshonite is 6 and that of Lherzolite is 6.5. The types of Shoshonite are Intermediate volcanic 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 Shoshonite is white to grey while that of Lherzolite is white. The specific heat capacity of Shoshonite is 0.79 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.Shoshonite is heat resistant, pressure resistant whereas Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant.
