'epidote-bearing' originates from English, specifically the combination of the noun 'epidote' and the verb 'bear' with the adjectival suffix '-ing', where 'epidote' names the mineral (from Greek) and 'bear' means 'to carry' or 'to contain'.

'epidote' changed from Greek 'epidōtos' (epidotos) to Medieval Latin 'epidotus', then through French 'épidote' into modern English 'epidote'; 'bearing' derives from Old English 'beran' (to carry) and developed into the present participle forming adjectives like '...-bearing'.

Initially the element 'epidote' referred to the mineral name (originally from Greek meaning 'added' or 'given in addition'), and 'bearing' retained the meaning 'carrying/containing'; combined, the phrase came to mean 'containing the mineral epidote' and is used as a technical descriptive adjective in geology.
