Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.   
Ijolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Scoria vs Ijolite 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 Ijolite Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite. 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 Ijolite information and Scoria vs Ijolite characteristics in the upcoming sections.
