More about Evaporite and Rapakivi Granite

Here you can know more about Evaporite and Rapakivi Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Rapakivi Granite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Rapakivi Granite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Rapakivi Granite, 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, Rapakivi Granite is available in black, grey, orange, pink, white colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Rapakivi Granite is Veined or Pebbled. Properties of rock is another aspect for Evaporite vs Rapakivi Granite. The hardness of Evaporite is 2-3 and that of Rapakivi Granite is 6-7. The types of Evaporite are Not Available whereas types of Rapakivi Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite and Hybrid Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Rapakivi Granite is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Rapakivi Granite is 0.79 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 Rapakivi Granite is heat resistant, wear resistant.
