Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.   
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Scoria vs Shonkinite 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 Scoria and Shonkinite Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. Shonkinite is a rare, dark-coloured and intrusive igneous rock which contains augite and orthoclase feldspar as its primary constituents. 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 Scoria vs Shonkinite information and Scoria vs Shonkinite characteristics in the upcoming sections.
