Aragonite and oysters
- 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
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."
25 km from where ?
"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.
I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Aragonite's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT⚡ 02:05, 27 April 2015 (UTC)
