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.
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.

Dacite vs Wackestone 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 Wackestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dacite and Properties of Wackestone. Learn more about Dacite vs Wackestone in the next section. The interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Wackestone include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Dacite and Wackestone, 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 Wackestone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Dacite and Wackestone
Here you can know more about Dacite and Wackestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dacite and Wackestone 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 Wackestone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Dacite vs Wackestone, 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, Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Dacite is Vesicular and that of Wackestone is Rough and Dull. Properties of rock is another aspect for Dacite vs Wackestone. The hardness of Dacite is 2-2.25 and that of Wackestone is 2-3. The types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite whereas types of Wackestone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dacite and Wackestone is white. The specific heat capacity of Dacite is 0.92 kJ/Kg K and that of Wackestone is 0.39 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 Wackestone is heat resistant, impact resistant.
