Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

Scoria vs Migmatite 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 Migmatite Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components. 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.
