A Guide to Basalt: A Common, Fine-grained, Dark-Colored Volcanic Rock
August 17, 2023 by Mcnair, B. Basalt is a hard, fine-grained, dark-colored volcanic or extrusive rock. It has primarily calcium-rich plagioclase and augite. Also, it may have minor amounts of other minerals like quartz, olivine, foids, alkali feldspar, biotite, and amphibole. This rock is undoubtedly popular, only rivaled by granite.

Characteristics of terrestrial basaltic rock populations: Implications
Basaltic rock sphericity appears to be controlled primarily by cooling fractures in the rock. The exponential shape of the size-frequency distributions of these sites are similar to those predicted by fracture and fragmentation theory, which further argues that these distributions are being dominantly controlled by the initial fracture and ...

Basalt | Encyclopedia MDPI
Basalt (/bəˈsɔːlt, ˈbæsɒlt, -sɔːlt/) is a mafic extrusive igneous rock formed from the rapid cooling of magnesium-rich and iron-rich lava exposed at or very near the surface of a terrestrial planet or a moon. More than 90% of all volcanic rock on Earth is basalt. Basalt lava has a low viscosity, due to its low silica content, resulting in rapid lava …

Basalt Rock
Basalt is an extrusive igneous or volcanic rock that has a low silica content, dark in colour, and is very rich in iron and magnesium. Basalt rock is mainly composed of pyroxene, olivine, and plagioclase and is the most common rock on the earth's surface. The texture of basalt rocks is coarsely porous as those holes are left by gas bubbles.
