The 9 pages that link to Porphyritic texture, each with the reason it gives.

• BasaltRelated: Basalt can preserve this texture when crystals grow before lava erupts and cools.

• Igneous rockRelated: Its two crystal sizes record contrasting stages or rates of cooling.

• AndesiteRelated: Many andesites record two-stage cooling through this texture.

• Volcanic rockRelated: It records a shift from slow crystallization to rapid cooling.

• Extrusive rockRelated: Two-stage cooling can produce large crystals before lava solidifies rapidly at the surface.

• DaciteRelated: Many dacites contain conspicuous crystals formed before the remaining melt cooled quickly.
