Formation
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.
Granite is an igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks

More about Turbidite and Rapakivi Granite
Here you can know more about Turbidite and Rapakivi Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Rapakivi Granite consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand 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 Turbidite vs Rapakivi Granite, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, green, grey, pink colors whereas, Rapakivi Granite is available in black, grey, orange, pink, white colors. Appearance of Turbidite is Dull and Banded and that of Rapakivi Granite is Veined or Pebbled. Properties of rock is another aspect for Turbidite vs Rapakivi Granite. The hardness of Turbidite is 3 and that of Rapakivi Granite is 6-7. The types of Turbidite are Sedimentary rock 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 Turbidite and Rapakivi Granite is white, greenish white or grey. The specific heat capacity of Turbidite is 0.92 kJ/Kg K and that of Rapakivi Granite is 0.79 kJ/Kg K.
