IPA: /ˈæfənaɪt/
KK: /æfəˈnaɪt/
A type of rock that is very dense and has a uniform texture, with its components being too small to be seen without a microscope.
The geologist studied the aphanite to understand its formation process.
Aphanite is derived from the Greek word "aphanes" (meaning invisible or not visible) combined with the suffix "-ite" (commonly used to denote minerals or rocks). The term aphanite refers to a type of volcanic rock that is fine-grained and not easily visible to the naked eye.
Think of the Greek word for invisible ('aphanes') to remember that aphanite is a rock that is not easily seen due to its fine-grained texture.
