Andrew Alden/Flickr. Basalt is an extrusive or intrusive rock that makes up most of the world's oceanic crust. This specimen erupted from Kilauea volcano in 1960. Basalt is fine grained so the individual minerals are not visible, but they include pyroxene, plagioclase feldspar, and olivine.These minerals are visible in the coarse-grained, …

Basalt is a dark-colored, dense rock composed primarily of plagioclase feldspar and pyroxene. It is the most common rock type found in oceanic crust and is an important component of the Earth's continental crust. Basalt is formed through the rapid cooling and solidification of magma at Earth's surface, resulting in the formation of lava flows […]

Give It Some Thought: Different Igneous Rocks of the Same Mineral Composition Extrusive and intrusive rocks containing similar minerals can be categorized by their composition of dark and light-colored silicates, and a difference in texture may distinguish them as different rock types. Coarse-grained textures are evidence that minerals cooled slowly, deep in …

Example: Basalt porphyry. Vesicular volcanic rocks: Vesicular is the adjective used to modify the name of any fine-grained igneous (volcanic) rock which has vesicles (holes from gas bubbles), making a cinder-like or clinker-like appearance. Example: Vesicular basalt. Scoria: Basalt with over 50% vesicles. It looks like cinders.

Basalt. Basalt is an extrusive igneous rock consisting primarily of plagioclase feldspar and pyroxene minerals. It is fine-grained (aphanitic) and dark in color, often with visible voids formed from gas bubbles. It is the extrusive equivalent of gabbro.
