Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

More about Basanite and Whiteschist
Here you can know more about Basanite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Whiteschist consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Whiteschist, the texture, color and appearance plays an important role in determining the type of rock. Basanite is available in black, brown, green, grey, red, white colors whereas, Whiteschist is available in colourless, green, grey, white colors. Appearance of Basanite is Glassy or Pearly and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Basanite vs Whiteschist. The hardness of Basanite is 7 and that of Whiteschist is 1.5. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Whiteschist are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basanite and Whiteschist is white. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Whiteschist 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.Basanite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Whiteschist is heat resistant.
