Etymology
Rhyo lite + dacite : a rock intermediate between rhyolite and dacite that is the extrusive equivalent of granodiorite
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Formation
Rhyodacite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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.

More about Rhyodacite and Turbidite
Here you can know more about Rhyodacite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhyodacite and Turbidite consists of mineral content and compound content. The mineral content of Rhyodacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Rhyodacite vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Rhyodacite is available in black to grey, dark greenish - grey colors whereas, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Rhyodacite is Skeletal and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Rhyodacite vs Turbidite. The hardness of Rhyodacite is 5.5-6 and that of Turbidite is 3. The types of Rhyodacite are Not Available whereas types of Turbidite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Rhyodacite is black while that of Turbidite is white, greenish white or grey. The specific heat capacity of Rhyodacite is 1.12 kJ/Kg K and that of Turbidite 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.Rhyodacite is heat resistant whereas Turbidite is heat resistant.
