1. Aphanite

   Aphanites (adj. aphanitic; from Ancient Greek αφανης (aphanḗs) 'invisible') are igneous rocks that are so fine-grained that their component mineral crystals are not visible to the naked eye (in contrast to phanerites, in which the crystals are visible to the unaided eye). This geological texture results from rapid cooling in volcanic or hypabyssal (shallow subsurface) environments. As a rule, the texture of these rocks is not the same as that of volcanic glass (e.g., obsidian), with volcanic glass being non-crystalline (amorphous), and having a glass-like appearance.Aphanites are commonly porphyritic, having large crystals embedded in the fine groundmass, or matrix. The larger inclusions are called phenocrysts. They consist essentially of very small crystals of minerals such as plagioclase feldspar, with hornblende or augite, and may contain also biotite, quartz, and orthoclase.

1. aphanite

   Aphanite is a type of volcanic rock characterized by its fine-grained texture and glassy surface. The rock is so fine-grained that most of its mineral constituents are not visible to the naked eye. The term is derived from the Greek word 'aphanes', meaning 'invisible'. This term is frequently used in geological studies and can refer to various types of finely crystalline or glassy rocks, including certain types of basalt and rhyolite.

1. Aphanite

   Aphanite, or aphanitic as an adjective, is a name given to certain igneous rocks which are so fine-grained that their component mineral crystals are not detectable by the unaided eye. This geological texture results from rapid cooling in volcanic or hypabyssal environments. As a rule, the texture of these rocks is not quite the same as that of volcanic glass, with volcanic glass being even finer grained than aphanitic rocks, and having a glass-like appearance. Aphanites are commonly porphyritic, having large crystals embedded in the fine groundmass or matrix. The large inclusions are called phenocrysts. They consist essentially of very fine-grained minerals, such as plagioclase feldspar, with hornblende or augite, and may contain also biotite, quartz, and orthoclase.
