I made some some edits to clarify the whole Phosphate/apatite group situation. I think that this artical is ready to pass the review User:Epbr123, but I dont know how to proceed from here, sorry. Let me know how to help and what is needed. Kevmin 04:33, 11 June 2007 (UTC)[reply]

The article has been placed at

Wikipedia:Good article candidates and there are instructions there if you feel you'd like to pass the article yourself. You would have to check that the article meets the six Good Article criteria, which includes things like the article having reliable sources and having the right style. If you don't feel you're able to check against these criteria, the article would probably get reviewed by someone else within a few days. Thanks for all your help.

1. looks like a nice article
2. passes the quick fail criteria with spelling, sections, references, no contension, neutral, images have GPL document licence
3. however I am placing on hold so it can have some quick improvements
4. suggestions
   1. compare to Material properties of diamond as the only other mineral GA article. I am surprised there are not more.
   2. some sentences have ; breaks would be better as 2 separate sentences
   3. References are quite light on - but do cover the material
   4. There are no primary references
5. Missing
   1. Optical data - birefringience=0.0660, dispersion
   2. Atom arrangement &- Cell Dimensions: a = 10.331;, c = 7.343; Z = 2; Volume = 678.72
   3. occurrence in arid climates
   4. % of vanadium 10.79%, %lead is 73.15% - from webmineral
   5. A list of places that actually mine the mineral, process used to extract vanadium in more detail
6. corrections
   1. unit for molecular weight is g/mol rather than gm

Looks as if most issues are addressed! 1.2 1.4 2.1 2.2 2.3 2.4 3.1 all covered. Still there is nothing about mines or limited amount on 'roasting'.

'Heating of vanadium ore or residues from other processes with salt NaCl or sodium carbonate Na2CO3 at about 850°C gives sodium vanadate NaVO3. This is dissolved in water and acidified to give a red solid which in turn is melted to form a crude form of vanadium pentoxide V2O5. Reduction of vanadium pentoxide with calcium gives pure vanadium. ' -- is found in the vanadium article.

In Vanadium there is this:

'Vanadium was originally discovered by Andrés Manuel del Río (a Spanish-born Mexican mineralogist) in Mexico City, in 1801. He called it "brown lead" (now named vanadinite).' — if this is really talking about vanadinite then this should be in this article. GB 21:28, 26 June 2007 (UTC)[reply]

with the lastest additions, all the requirements for GA are met. A hold is supposed to last 2 days, to allow other editors to contribute or comment. GB 02:28, 27 June 2007 (UTC)[reply]

To get to FA the style of writing will need to be improved - but I am not qualified to assess this. Other possible aditions could be a diagrametric representation of the crystal with axes and angles labelled, a diagram of the atom arrangement. A transmission spectrum of the red crystal, along with an explanation of why the crystal is red for the basic section. What happens when the mineral weathers. More on how it is formed and what other substances it is associated with. Tests such as closed tube pyrolosis, borax bead, charcoal with reducing and oxidising flame. Reactions with acids. Other properties could include fracture. There could be mrre information on the X-ray image. —Preceding unsigned comment added by Graeme Bartlett (talk • contribs) 15:56, June 29, 2007
