Formation
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

Amphibolite vs Turbidite 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. Amphibolite vs Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Amphibolite and Properties of Turbidite. Learn more about Amphibolite vs Turbidite in the next section. The interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Amphibolite and Turbidite, they have various applications in construction industry. The uses of Amphibolite in construction industry include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone and that of Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.
More about Amphibolite and Turbidite
Here you can know more about Amphibolite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Amphibolite and Turbidite consists of mineral content and compound content. The mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Amphibolite vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Amphibolite is available in black, brown, green, grey colors whereas, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Amphibolite is Foliated and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Amphibolite vs Turbidite. The hardness of Amphibolite is 6-7 and that of Turbidite is 3. The types of Amphibolite are Hornblendite whereas types of Turbidite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Amphibolite is white to grey while that of Turbidite is white, greenish white or grey. The specific heat capacity of Amphibolite is Not Available and that of Turbidite 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.Amphibolite is heat resistant, pressure resistant, wear resistant whereas Turbidite is heat resistant.
