Talk:Rhomb porphyry

This is not a rock type. Rock types should conform to the IUGS or other recognised classification scheme. This should be removed, and placed under a sub-category of porphyry, as it is a textural variation. In fact, you could throw it under tuff.Rolinator 05:00, 20 December 2005 (UTC)

I have moved the Rhomb Porphyry information and links to porphyry (geology) so it is preserved there; I have also added it in to latite which is what it apparently is according to the QAPF. This has been done to bring the list of rocks in to line with the above; it has o be a recognised rock type and not a textural variation. Rolinator 12:40, 1 March 2006 (UTC)
