Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.   
Essexite is a type of igneous rock, which is usually dark grey to black plutonic rock. For the formation of essexite, suitable magma with exact composition of K, Ba, Rb, Cs, Sr should be produced.

Scoria vs Essexite  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 Essexite  Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. Essexite which is also known as nepheline monzogabbro, is a dark gray or black holocrystalline plutonic Iigneous Rock. 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 Essexite  information and Scoria vs Essexite  characteristics in the upcoming sections.
