Intrusive features are typically classified as plutonic rocks, especially inside of a volcano. Comparatively, extrusive features are also classified as volcanic rocks.
Is pumice a metamorphic rock?
No pumice is not a porphyritic igneous rock, a porphyritic rock is characterized by the presence of phenocrysts (large mineral grains) and very small mineral grains with none in between. This implies that there was two different stages of cooling. Pumice is an extrusive igneous rock that cooled very quickly.
How are intrusive features classified?
