Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.

Evaporite vs Ignimbrite 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. Evaporite vs Ignimbrite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Ignimbrite. Learn more about Evaporite vs Ignimbrite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Ignimbrite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Evaporite and Ignimbrite, they have various applications in construction industry. The uses of Evaporite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Ignimbrite include Building houses or walls, Construction aggregate.
More about Evaporite and Ignimbrite
Here you can know more about Evaporite and Ignimbrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Ignimbrite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Ignimbrite includes Apatite, Biotite, Calcite, Chlorite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Ignimbrite, the texture, color and appearance plays an important role in determining the type of rock. Evaporite is available in colourless, green, grey, silver, white colors whereas, Ignimbrite is available in beige, black, brown, grey, pink, white colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Ignimbrite is Dull, Vesicular and Foilated. Properties of rock is another aspect for Evaporite vs Ignimbrite. The hardness of Evaporite is 2-3 and that of Ignimbrite is 4-6. The types of Evaporite are Not Available whereas types of Ignimbrite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Ignimbrite is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Ignimbrite is 0.20 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Evaporite is heat resistant, pressure resistant whereas Ignimbrite is heat resistant, impact resistant, pressure resistant, wear resistant.
