Amphibolite is a common term used in geology to describe a specific type of metamorphic rock that is created from the transformation of basalt or similar volcanic rocks. While the word amphibolite itself is relatively unique, there are several synonyms that are commonly used to describe this type of rock. These synonyms include hornblendite, gneiss, greenstone and schist. Each of these terms refers to a distinct characteristic or form of amphibolite, but all are related to the same general type of rock. Whether used in scientific research or everyday conversation, the various synonyms for amphibolite help to make this complex field of study more accessible and understandable to all.
