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.
  
Comendite is a type of Igneous rock which is formed due to cooling and solidification of lava or magma. It may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Turbidite and Comendite
Here you can know more about Turbidite and Comendite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Comendite consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand and mineral content of Comendite includes Albite, Amphibole, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Turbidite vs Comendite, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas, Comendite is available in blue, bluish - grey colors. Appearance of Turbidite is Dull and Banded and that of Comendite is Foliated. Properties of rock is another aspect for Turbidite vs Comendite. The hardness of Turbidite is 3 and that of Comendite is 6-7. The types of Turbidite are Not Available whereas types of Comendite are Rhyolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Turbidite is white, greenish white or grey while that of Comendite is bluish black. The specific heat capacity of Turbidite is 0.92 kJ/Kg K and that of Comendite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Turbidite is heat resistant whereas Comendite is heat resistant, impact resistant.
