[edit] Added

I have added a modern view of lamprophyres according to the IUGS (though I hesitate to think of what they'd say about this!). The previous entry was dated and gave no info on chemistry, genesis and so forth, but it did contain very useful info on the particular varieties of lamprophyres. As far as I am aware, having read Rock (1991) and Mitchell (1994), these two were at loggerheads about the issue of lamprophyres for years. The definition given for their genesis is pretty accurate as long as you don't start citing evidence; then you start running into 10,000 papers on melting models, etc etc and it falls apart as per usual for these rocks.

BTW, feel free to whack any and all 1911EB text that is obsolete; we just use it as a placeholder until somebody knowledgeable like yourself comes along. Stan 06:35, 19 December 2005 (UTC)

It is actually a fairly good petrological guide. Lamprophyre study hasn't advanced much since the 1950's due to contentious arguments and bitching. So mos of the 1911 stuff is fairly good.Rolinator 10:50, 24 December 2005 (UTC)

Note: There is a new reference that tries to integrate ultramafic lamprophyres into the IUGS classification scheme (Tappe et al, 2005, Journal of Petrology 46:1893-1900).

If there is anywhere that has that as a pdf, that you or anyone else knows about, I'd be extremely interested in it. Also, it might incidentally help the article....Rolinator 03:46, 31 January 2006 (UTC)
