Minerals in an igneous rock do not all form at the same time. In this porphyritic rock, the larger crystals are a feldspar that were already formed before the lava became solidified completely. The fine groundmass is composed predominantly of a mixture of very fine-grainedcrystals of quartz and feldspars.
