Talk:Hypersthene

Merge if you find it necessary (I don't) - I am aware the IMA has abandoned the name, but it fills a descriptive slot and is still used in (at least some) modern mineralogy texts. Enstatite is the pure or nearly pure, endmember (< 12% FeSiO3) of the series and the rare ferrosilite the iron endmember. I would say that most samples are say 25 - 50% FeSiO3 and hypersthene seems a reliable term to describe these and backed by historical usage. Additionally bronzite is used by many sources for the 12 - 25% FeSiO3 range. Merge, but keep and explain the usage - don't eliminate a meaningful name just because the IMA dosen't like it. What would we call the hypersthene-andesite in the current page? Vsmith 00:09, 28 Dec 2004 (UTC)


 * Fair comment - I was not planning to remove all reference to hypersthene and my only real rationel for merging is that much of the information for members of a series is duplicated. I have removed the merge notice, will borrow useful info and leave the issue for later (when enstatite is in better shape). If I remember properly we should use iron rich enstatite-andesite for the rock but not named units, but (1) I am not a petrologist and (2) that's a bit of a mouthful.  Andreww 21:10, 28 Dec 2004 (UTC)
