<h2>Phenocrysts and Porphyritic texture
</h2>
Explanation:
- The early formed crystals are of phenocrysts and the texture of these crystals is porphyritic texture.
- This crystallization occurs when early-forming plagioclase crystals which are rich in calcium start coating with plagioclase crystals which are rich in sodium.
- On cooling, the magma is then processed in a volcanic eruption, after the eruption the liquid which is left behind will start cooling and forms a porphyritic texture.
