'non-andesitic' originates from English, specifically combining the prefix 'non-' (from Latin 'non', meaning 'not') and 'andesitic' (from 'andesite', named after the Andes Mountains).

'andesite' was named in the 19th century after the Andes Mountains; the adjective 'andesitic' developed from 'andesite' to mean 'of or pertaining to andesite', and the negative prefix 'non-' was later attached to form 'non-andesitic' meaning 'not andesitic'.

Initially related simply to the rock name 'andesite' and its adjective form 'andesitic'; over time the prefixed form 'non-andesitic' has been used in geological descriptions to denote materials or compositions that do not exhibit andesitic characteristics.
