Scoria is an extrusive igneous rock composed of highly vesicular volcanic glass, formed from violent eruption, depressurization, and rapid cooling of lava. It is almost always dark in color with a mafic or intermediate composition. Scoria is can be differentiated from pumice by its inability to float on water.

These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff. Pictures and brief descriptions of some common igneous rock types are shown on this page. Dacite is a fine-grained, extrusive igneous rock that is usually light in color. It has a composition that is intermediate between rhyolite and andesite.

Composition refers to a rock’s chemical and mineralogical make-up. For igneous rock, the composition is generally divided into four groups: ultramafic, mafic, intermediate, and felsic. These groups refer to differing amounts of silica (SiO2), iron (Fe), and magnesium (Mg) found in the minerals that make up the rocks. Figure.

Classification By Mineral Abundance. Igneous rocks can be divided into four categories based on their chemical composition: felsic, intermediate, mafic, and ultramafic. The diagram of Bowen’s reaction series ( Figure 4.6) shows that differences in chemical composition correspond to differences in the types of minerals within an igneous rock.
