Asparagus Stone

 * I don't think that "asparagus stone" is a term in common usage. I've never heard it, I've asked other rockhounds and they've never heard it, and, more objectively, it scores less than 3k hits on google that aren't direct wikipedia clones.  IMO, this factoid ought to be removed. Eoseth 02:06, 21 May 2007 (UTC)

Where does apatite come from ?
Where does apatite mineral originally come from ? Volcanos ? Precipitation from primordial seas ? Eregli bob (talk) 12:52, 17 March 2008 (UTC)

Apatite is mainly mined from geologic deposits in the earth. It is often associated with limestone deposits as it too is a calcareous rock formed from marine deposits. This is the source of apatite, marine calcareous deposits. One of the largest sources is in Florida USA Polk and Highlands counties up river from Ft. Myers FL USA. Apatite is processed via reaction with Sulfuric Acid to produce Phosphate fertilizers PO4, HPO4, H2PO4 etc.. These are used to fertilize all agricultural crops. The tobacco comment about fertilizing with apatite is ill informed. Putting apatite on a crop would do nothing, it is not able to be uptaken by a plant. It would be the same as adding any other inert substance to a plant's growth medium ie quartz. To be used as a fertilizer it must be processed via acid decomposition (think tooth decay apatite is a geological form of enamel they are nearly identical minerals).173.18.177.11 (talk) 16:32, 26 May 2010 (UTC)

Confused on footnote 7 - Is it that other than smoking etc products grown with apatite based fertilizer that it is nonradioactive? Maybe only some sources of apatite are radioactive? Footnote 7 is interesting - about rare earth minerals - we rely on China for this needed import it appears. 159.105.80.141 (talk) 15:05, 5 February 2010 (UTC)

Lunar science section
I re-created the section on lunar science, as apatite's significance in lunar science has very suddenly increased in importance. If there are any stylistic or other issues with this section, please edit the existing text or replace it with better text instead of simply deleting the section. dmosher 19:12, 18 June 2010 (UTC)

I think the math for the water depth is off. Using the lunar mass and radius from the moon page, I get 64 ppb global bulk composition as 12 cm depth. Cwmagee (talk) 11:17, 19 October 2010 (UTC)


 * I don't know how to edit the reference list, but his name is "McCubbin" not "McCubbina", I assume that is a typo. — Preceding unsigned comment added by 2601:181:4600:a7c0:c00d:f829:2ce4:3ffa (talk • contribs) 17:49, 27 August 2021 (UTC)


 * Thanks for reporting this. I have corrected the name of "McCubbin" in the list of source references. GeoWriter (talk) 21:23, 27 August 2021 (UTC)

Room Temperature Superconductivity
If I understand correctly, taking lead apatite and substituting copper for one of the two lead sites gives the current only candidate for room temperature, standard pressure superconductor.
