==Geology==
Unlike a true [[marble]], it is not a [[metamorphic rock]], but is so-called because it can take a fine polish. Concentrations of such corals as ''[[Dibunophyllum bipartitum]]'' and of [[brachiopod]] remains contribute to its attractiveness when sections are polished.<ref>Stone et al 2010 ''British Regional Geology: Northern England'' (5th edition) (Keyworth, Nottingham: British Geological Survey) pp238-254</ref><ref name="lawrence" />{{rp|40}}
==Use==
It is cut and polished for use as ornate stone, and was much desired for church decoration, particularly during the Middle Ages.<ref>{{cite web |url=https://weardalemuseum.org.uk/news-frosterley-marble-to-come-to-museum |title=Frosterley Marble Font to Come to the Museum |publisher=Weardale Museum |date=15 April 2020 |access-date=11 October 2023}}</ref> The decorative columns found in [[Durham Cathedral]] date from about 1350.
