Phonolite vs Dacite

Phonolite vs Dacite 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 Phonolite and Dacite Reserves. Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic. Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite. 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 Phonolite vs Dacite information and Phonolite vs Dacite characteristics in the upcoming sections.

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