Basalt Facts

Basalt is Earth's most abundant bedrock, and a very important rock. The Earth's ocean basins are underlain by basalt, but it is less common on continents. However, lava flows and flood basalts underlie several percent of Earth's land surface. It is an igneous rock and is usually finegrained and darkcolored, composed mainly of plagioclase and pyroxene minerals.

Rock properties OoCities

Finegrained and lower porosity igneous rocks, such as basalt and diabase (dolerite) are generally higher in rock hardness than that of coarser grained igneous rocks, such as granite, diorite, and gabbro. As a result, the mineral grains of finegrained igneous rocks are more tightly held together than that of coarsegrained igneous rocks.
