Formation
Hornblendite 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.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

More about Hornblendite and Evaporite
Here you can know more about Hornblendite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Evaporite consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Igneous Rocks. When we have to compare Hornblendite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Hornblendite is available in black, brown, green, grey colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Hornblendite is Foliated and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Hornblendite vs Evaporite. The hardness of Hornblendite is 6-7 and that of Evaporite is 2-3. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite whereas types of Evaporite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hornblendite is white to grey while that of Evaporite is white. The specific heat capacity of Hornblendite is Not Available and that of Evaporite 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.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
