Definition
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock

Etymology
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939
From German which means hornstone

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Hornfels is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Turbidite and Hornfels
Here you can know more about Turbidite and Hornfels. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Hornfels consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand and mineral content of Hornfels includes Andalusite. You can also check out the list of all Sedimentary Rocks. When we have to compare Turbidite vs Hornfels, 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, Hornfels is available in brown, dark greenish - grey, green, reddish brown colors. Appearance of Turbidite is Dull and Banded and that of Hornfels is Dull. Properties of rock is another aspect for Turbidite vs Hornfels. The hardness of Turbidite is 3 and that of Hornfels is 2-3. The types of Turbidite are Not Available whereas types of Hornfels are Biotite hornfels. 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 Hornfels is unknown. The specific heat capacity of Turbidite is 0.92 kJ/Kg K and that of Hornfels is 0.84 kJ/Kg K. 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 Hornfels is heat resistant, impact resistant, pressure resistant.
