Basalt or andesite could fit this description.
The texture of intrusive igneous rocks is phaneritic, which is characterized by coarse-grained large crystals that are visible to the naked eye. The texture of volcanic rocks, meanwhile, is porphyritic, which is characterized by fine-grained crystals.
Granite is a coarse grained igneous rock without Pyroxene.
Coarse grained, Medium grained, and fine grained.
Fine grained rocks are considered aphanitic.
Coal is fine grained, lack of visible texture.
