Definition
Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Origin
Romania and Moldova, Europe
European Foreland Basins
Discoverer

Arnold H. Bouma
Etymology
From Dacia, a province of the Roman Empire which lay between the Danube River and Carpathian Mountains where the rock was first described
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Formation
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.
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.

Dacite vs Turbidite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Dacite vs Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dacite and Properties of Turbidite. Learn more about Dacite vs Turbidite in the next section. The interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Dacite and Turbidite, they have various applications in construction industry. The uses of Dacite in construction industry include As dimension stone, Construction aggregate, For road aggregate, Landscaping and that of Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.
More about Dacite and Turbidite
Here you can know more about Dacite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dacite and Turbidite consists of mineral content and compound content. The mineral content of Dacite 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 Dacite vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Dacite is available in bluish - grey, brown, grey, light to dark grey colors whereas, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Dacite is Vesicular and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Dacite vs Turbidite. The hardness of Dacite is 2-2.25 and that of Turbidite is 3. The types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite 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 Dacite is white while that of Turbidite is white, greenish white or grey. The specific heat capacity of Dacite is 0.92 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.Dacite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Turbidite is heat resistant.
