Aragonite and oysters[edit]

Aragonite. Same as oyster shells found in Farm Supply Stores? —Preceding unsigned comment added by 208.17.215.235 (talkcontribs)

I've just had a look in my copy of Barnes (Barnes, R. D., 1987, Invertebrate Zoology (Fifth Edition), Saunders College Publishing, Philadelphia, USA, pg. 404), and he suggests that shells of bivalves may be entirely aragonite (he describes this as the "primitive" state), or a mixture of calcite and aragonite. He goes on at some length about the way in which the shell is laid down in prisms, laths or tablets of calcium carbonate. Anyway, I hope this answers your question. --Plumbago 08:03, 6 September 2007 (UTC)

Aragonite and blueschist[edit]

Is the following really true?

"The young age of the California blueschists has been famously demonstrated by the finding therein of aragonite not yet reverted to calcite."

If so, it needs a citation. If not, it should be removed.Wilson44691 (talk) 09:55, 12 April 2010 (UTC)

25 km from where ?[edit]

"The type location for aragonite is Molina de Aragón (Guadalajara, Spain), 25 km from Aragon for which it was named in 1797"

25 km from Aragon, doesn't quite make sense. Aragon is a province(region, whatever), not a town.
