Where Is Scoria Found? | Reference

Scoria is created as gas escapes from a volcano and rock solidifies around it. Scoria builds up around the vent of a volcano. The cone-shaped hill formed by scoria is called a cinder cone. Some parts of the world have large areas with ple cinder cones called volcano fields. Volcanoes that produce scoria usually have brief eruptions and are not very tall.

Igneous Rocks: Formation, Types and Examples | Earth Eclipse

Intrusive igneous rocks are formed when the magma cools off slowly under the earth's crust and hardens into rocks. Gabbro and granite are examples of intrusive igneous rocks. Intrusive rocks are very hard in nature and are often coarse-grained. Extrusive Igneous Rocks.

Igneous rock composition. Such rocks are said to have a mafic composition. Mafic magma crystallizes to form basalt or gabbro. If a rock contains a small proportion of iron, the resultant rock will be light in color and is said to have a felsic composition. Felsic magma solidifies to form rhyolite or granite.

Scoria - Infogalactic: the planetary knowledge core

Scoria is relatively low in density as a result of its numerous macroscopic ellipsoidal vesicles, but in contrast to pumice, all scoria has a specific gravity greater than 1, and sinks in water. The holes or vesicles form when gases that were dissolved in the magma come out of solution as it erupts, creating bubbles in the molten rock, some of which are frozen in place as the rock cools and solidifies.
