lacking anorthosite
Etymology
'anorthosite-poor' originates from modern English compounding of 'anorthosite' and 'poor'; 'anorthosite' comes from New Latin/Greek geological terminology referring to the plagioclase-rich rock, and 'poor' comes from Old English meaning 'lacking or deficient'.
'anorthosite' entered geological usage in the 19th–20th century from New Latin based on Greek roots used in mineralogy; 'poor' descends from Old English 'pōr' meaning 'deficient'. The hyphenated compound 'anorthosite-poor' developed in technical geological writing to describe rocks or terrains with low anorthosite content.
Initially 'anorthosite' named a specific rock type; over time the compound meaning 'lacking anorthosite' has been used directly in descriptions of lithology and regional composition.
