the textures are similar yes but gabbro is made up of calcite and olivine while granite contains biotite mica, feldspar, and quartz.
Quartz
Most likely, as the major rock forming minerals are from the silicate group. Examples are feldspar, quartz, olivine, and mica.
Quartz, Potassium Feldspar, Plagioclase Feldspar, Muscovite (mica), Biotite (mica), Amphibole (hornblende), Pyroxene, Olivine, Calcite, Dolomite.
Biotite and muscovite micas, quartz, magnetite, olivine, amphiboles, and feldspars.

No. Oil is a liquid and coal is a rock. Neither is a silicate mineral such as quartz, olivine, mica, and feldspar.

That would be mica...and it's spelled "quartz"
