More about Hawaiite and Andesite
Here you can know more about Hawaiite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hawaiite and Andesite consists of mineral content and compound content. The mineral content of Hawaiite includes Olivine, Plagioclase, Pyroxene and mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Hawaiite vs Andesite, the texture, color and appearance plays an important role in determining the type of rock. Hawaiite is available in black, brown, light to dark grey colors whereas, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Hawaiite is Dull and Soft and that of Andesite is Dull and Soft. Properties of rock is another aspect for Hawaiite vs Andesite. The hardness of Hawaiite is 6 and that of Andesite is 7. The types of Hawaiite are Volcanic rock whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hawaiite is while that of Andesite is white. The specific heat capacity of Hawaiite is 0.84 kJ/Kg K and that of Andesite is 2.39 kJ/Kg K.
