Examples of aphanitic igneous rock include basalt, andesite and rhyolite.
In thin section, dacites may have an aphanitic to porphyritic texture.
Generally speaking, phaneritic implies an intrusive origin; aphanitic an extrusive one.
The individual crystals in an aphanitic igneous rock are not distinguishable to the naked eye.
It has an aphanitic to porphyritic texture and is intermediate in composition between andesite and rhyolite.
The result is an aphanitic rock with some larger crystals ( phenocrysts ) imbedded within its matrix.
These phases typically form aphanitic equigranular granoblastic massive sulfides, or are present as disseminated sulfides within rocks composed mostly of silicates.
The primary benefit of calculating a CIPW norm is determining what the ideal mineralogy of an aphanitic or porphyritic igneous rock is.
The rock has a very fine grained to aphanitic texture, and has a light blue-grey to a warm brown-grey range in colour.
Igneous rocks that have crystals large enough to be seen by the naked eye are called phaneritic; those with crystals too small to be seen are called aphanitic.
