oolith | oolite |

(rare) Oolite.
(geology) A rock consisting of spherical grains within a mineral cortex accreted around a nucleus, often of quartz grains.
*2004 , (Richard Fortey), The Earth , Folio Society 2011, p. 170:
*:Here and there are beds of oolites , for example, made of little rounded grains – like millet seed – that form only in agitated warm waters, such as you might find off the Bahamas today.
(countable, rare) An ooid or oolith.
