Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

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

Lherzolite vs Talc carbonate 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. Lherzolite vs Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lherzolite and Properties of Talc carbonate. Learn more about Lherzolite vs Talc carbonate in the next section. The interior uses of Lherzolite include Decorative aggregates, Entryways, Homes and Interior decoration whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Lherzolite and Talc carbonate, they have various applications in construction industry. The uses of Lherzolite in construction industry include Landscaping, Manufacture of magnesium and dolomite refractories, Used for flooring, stair treads, borders and window sills. and that of Talc carbonate include Source of calcium.
More about Lherzolite and Talc carbonate
Here you can know more about Lherzolite and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lherzolite and Talc carbonate consists of mineral content and compound content. The mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite and mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Igneous Rocks. When we have to compare Lherzolite vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas, Talc carbonate is available in colourless, grey, white colors. Appearance of Lherzolite is Glassy, Vesicular and Foilated and that of Talc carbonate is Soft. Properties of rock is another aspect for Lherzolite vs Talc carbonate. The hardness of Lherzolite is 6.5 and that of Talc carbonate is 1-2. The types of Lherzolite are Garnet Lherzolite whereas types of Talc carbonate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lherzolite and Talc carbonate is white. The specific heat capacity of Lherzolite is 0.95 kJ/Kg K and that of Talc carbonate is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Talc carbonate is heat resistant, wear resistant.
