- 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.
- Typically, they are less resistant to weathering than the enclosing aphanitic rock and, as a result, form pock-marks on the weathered surfaces of mafic rocks.
- Felsite is a petrologic field term used to refer to very fine-grained or aphanitic, light-colored volcanic rocks which might be later reclassified after a more detailed microscopic or chemical analysis.
- The earlier formed minerals will have formed slowly and remain as large crystals, whereas, sudden cooling causes the rapid crystallization of the remainder of the melt into a fine grained ( aphanitic ) matrix.
- "' Aphanite "', or "'aphanitic "'as an adjective ( from the geological texture results from rapid cooling in volcanic or hypabyssal ( shallow subsurface ) environments.
- The groundmass of these rocks is often aphanitic microcrystalline, with a web of minute feldspars mixed with interstitial grains of quartz or tridymite; but in many dacites it is largely vitreous, while in others it is felsitic or cryptocrystalline.
- "' Phonolite "'is an uncommon extrusive igneous rock, volcanic rock, of intermediate chemical composition between felsic and mafic, with texture ranging from aphanitic ( fine-grain ) to porphyritic ( mixed fine-and coarse-grain ).
- "' Varioles "'are millimeter-to centimeter-scale, light-colored, globular to spherical structures, that are conspicuously observable within aphanitic, mafic igneous rocks, such as basalt, komatiite, and tachylite, that comprise either pillow lavas, subaerial lava flows, or volcanic dykes.
