Basalt vs. Granite: Know the Difference
By Shumaila Saeed || Published on January 6, 2024
Basalt is a dark, fine-grained volcanic rock, formed from lava, while granite is a light-colored, coarse-grained igneous rock formed from cooled magma.
Key Differences
Basalt, a dark-colored volcanic rock, is formed from the rapid cooling of lava. Granite, in contrast, is a light-colored igneous rock, formed slowly from cooling magma deep within the earth.

Basalt is characterized by its fine-grained texture, a result of its rapid cooling process. Granite, however, has a coarse-grained texture due to its slower cooling, allowing larger crystals to form.

In terms of composition, basalt is primarily made up of plagioclase and pyroxene minerals. Granite is predominantly composed of quartz, feldspar, and mica.

Basalt is commonly found in oceanic crust and volcanic islands, forming from lava flows. Granite is typically found in continental crust, forming large intrusions like batholiths.

The density of basalt is higher compared to granite, making it heavier. Granite, with a lower density, is less heavy and is often used in construction and decorative architecture.

Granite
(rock) A group of igneous and plutonic rocks composed primarily of feldspar and quartz. Usually contains one or more dark minerals, which may be mica, pyroxene, or amphibole. Granite is quarried for building stone, road gravel, decorative stone, and tombstones. Common colors are gray, white, pink, and yellow-brown.

Granite
A crystalline, granular rock, consisting of quartz, feldspar, and mica, and usually of a whitish, grayish, or flesh-red color. It differs from gneiss in not having the mica in planes, and therefore in being destitute of a schistose structure.
