'aragonite-bearing' is a compound of 'aragonite' + English 'bearing'. 'aragonite' ultimately originates from the Spanish place name 'Aragón' (the region where the mineral was first identified), and 'bearing' comes from Old English 'beran', where 'beran' meant 'to carry'.

'aragonite' was named in the 19th century from the place name 'Aragón' with the mineral-forming suffix '-ite'; 'bearing' evolved from Old English 'beran' to Middle English 'beren' and later to modern English 'bear'/'bearing', producing the modern compound 'aragonite-bearing'.

Initially the elements referred separately to the place-derived mineral 'aragonite' and the verb 'to carry'; over time the compound came to mean 'containing the mineral aragonite' in geological descriptions.
