Definition

Definition

Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite
Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows

Formation

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.
Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.

Dacite vs Ignimbrite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Dacite and Ignimbrite Reserves. Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite. Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Dacite vs Ignimbrite information and Dacite vs Ignimbrite characteristics in the upcoming sections.

Dacite vs Ignimbrite 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 Ignimbrite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dacite and Properties of Ignimbrite. Learn more about Dacite vs Ignimbrite in the next section.

You can also check out the list of all Igneous Rocks. When we have to compare Dacite vs Ignimbrite, 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, Ignimbrite is available in beige, black, brown, grey, pink, white colors. Appearance of Dacite is Vesicular and that of Ignimbrite is Dull, Vesicular and Foilated. Properties of rock is another aspect for Dacite vs Ignimbrite. The hardness of Dacite is 2-2.25 and that of Ignimbrite is 4-6. The types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite whereas types of Ignimbrite are Pyroclastic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dacite and Ignimbrite is white. The specific heat capacity of Dacite is 0.92 kJ/Kg K and that of Ignimbrite is 0.20 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 Ignimbrite is heat resistant, impact resistant, pressure resistant, wear resistant.
