Definition
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
Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite

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

More about Marble and Dacite
Here you can know more about Marble and Dacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marble and Dacite consists of mineral content and compound content. The mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz and mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Marble vs Dacite, the texture, color and appearance plays an important role in determining the type of rock. Marble is available in black, blue, brown, grey, pink, white colors whereas, Dacite is available in bluish - grey, brown, grey, light to dark grey colors. Appearance of Marble is Veined and Shiny and that of Dacite is Vesicular. Properties of rock is another aspect for Marble vs Dacite. The hardness of Marble is 3-4 and that of Dacite is 2-2.25. The types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble whereas types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Marble and Dacite is white. The specific heat capacity of Marble is 0.88 kJ/Kg K and that of Dacite 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.Marble is heat resistant whereas Dacite is heat resistant, impact resistant, pressure resistant, wear resistant.
