Definition
Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

More about Dacite and Marble
Here you can know more about Dacite and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dacite and Marble 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 Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Dacite vs Marble, 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Dacite is Vesicular and that of Marble is Veined and Shiny. Properties of rock is another aspect for Dacite vs Marble. The hardness of Dacite is 2-2.25 and that of Marble is 3-4. The types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dacite and Marble is white. The specific heat capacity of Dacite is 0.92 kJ/Kg K and that of Marble is 0.88 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 Marble is heat resistant.
