Basalt vs. Granite: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on November 28, 2023
Basalt is a dark, fine-grained volcanic rock. Granite is a light-colored, coarse-grained igneous rock.

Key Differences

Basalt is formed from rapid cooling of lava at the Earth's surface, resulting in a fine-grained texture. Granite, however, forms deep within the Earth's crust from slow cooling of magma, leading to its coarse-grained texture.

In terms of composition, basalt is rich in magnesium and iron, giving it a darker color. While, granite is composed mainly of quartz and feldspar, contributing to its lighter color.

Basalt exhibits higher density and durability, making it suitable for construction materials. Whereas, granite, with its lower density but high strength, is favored for decorative purposes like countertops.

Basalt is typically found in oceanic plates and volcanic regions. In contrast, granite is common in continental crust, forming large mountain ranges.

The cooling rate of basalt allows for fewer crystal formations, resulting in a smoother texture. Meanwhile, granite cools slowly, allowing large crystals to form, giving it a granular texture.

Basalt

(mineral) A hard mafic igneous rock of varied mineral content; volcanic in origin, which makes up much of the Earth's oceanic crust.

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.
