Formation

Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

Scoria vs Lamprophyre 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 Lamprophyre Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions. 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 Lamprophyre information and Scoria vs Lamprophyre characteristics in the upcoming sections.

Scoria vs Lamprophyre 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. Scoria vs Lamprophyre characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Lamprophyre. Learn more about Scoria vs Lamprophyre in the next section. The interior uses of Scoria include Decorative aggregates and Interior decoration whereas the interior uses of Lamprophyre include Decorative aggregates and Interior decoration.
