Quizplus · Accepted Answer

The rock in the photograph exhibits large, distinct crystals (phenocrysts) embedded in a finer-grained matrix. This is characteristic of a porphyritic texture. There are no vesicles (small cavities left by gas bubbles), breccia (angular fragments cemented together), or glassy texture observed in this rock.
