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.

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.

Metamorphic rock can be coarse grained or fine grained.
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.
Gabbro

Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.
Visible crystals or grains would be referred to as a coarse grained texture.
