What are the igneous rock textures? - Answer glassy, porphyritic, phaneritic, aphanitic, pyroclastic, pegmatitic Glassy - Answer -occur during some volcanic eruptions when the lava is quenched so rapidly that crystallization cannot occur -the result is a natural amorphous glass with few or no crystals Porphyritic - Answer -mixed fine texture and coarse texture -develop when conditions during cooling of a magma change relatively quickly. The earlier formed minerals wil...
