Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Rhomb-porphyry 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 Evaporite and Rhomb Porphyry
Here you can know more about Evaporite and Rhomb Porphyry. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Rhomb Porphyry consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Rhomb Porphyry includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Rhomb Porphyry, 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, Rhomb Porphyry is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Rhomb Porphyry is Rough. Properties of rock is another aspect for Evaporite vs Rhomb Porphyry. The hardness of Evaporite is 2-3 and that of Rhomb Porphyry is 5-5.5. The types of Evaporite are Not Available whereas types of Rhomb Porphyry 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 Rhomb Porphyry is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Rhomb Porphyry 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.Evaporite is heat resistant, pressure resistant whereas Rhomb Porphyry is heat resistant, pressure resistant.
