The dark coarse-grained rock commonly used for buildings is basalt. This igneous rock is formed from the rapid cooling of lava and is known for its durability and strength. Basalt is often utilized in construction for its aesthetic appeal and resistance to weathering, making it suitable for both structural and decorative purposes. Its dense nature also provides excellent thermal and acoustic insulation properties.

Granite is a coarse grained igneous rock without Pyroxene.
A peridotite is a dense, coarse-grained igneous rock

granite
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
fine grained or coarse grained
The dark-colored mineral in coarse-grained igneous rocks is likely to be biotite or hornblende. These minerals are commonly found in rocks like diorite, gabbro, and basalt.
Granite is a coarse grained igneous rock without Pyroxene.
A peridotite is a dense, coarse-grained igneous rock
Yes, diorite is a coarse-grained igneous rock that typically contains a mixture of light and dark minerals. It forms from the slow cooling of magma deep within the Earth's crust, resulting in visible crystals that are larger than those in fine-grained rocks.
Metamorphic rock can be coarse grained or fine grained.
Gabbro
Fine grained rock exhibits a non-visible or nearly non-visible crystalline structure on a fractured surface. On the opposite end, a coarse grained rock exhibits mineral crystals of the rock's constituents on a fractured surface. The larger the crystals, the coarser grained is the rock. Basalt would be an example of a fine grained rock. Granite would be an example of a coarse grained rock.
Coarse
Granite is a coarse-grained intrusive rock commonly used for buildings and monuments due to its durability, strength, and aesthetic appeal. It is known for its wide range of colors and textures, making it a popular choice for construction projects that require both functionality and beauty.
