Mineralogical ClassificationArsenian pyromorphite?

17th Oct 2019 14:49 UTCKevin Conroy Manager

A recent discussion involving pyromorphite sparked my curiousity, so I went to the pyromorphite page to refresh my memory.   I noticed that arsenian pyromorphite wasn't listed.   After a quick read of some Google search results I'm wondering if it's a valid term that I should continue to use.   Thoughts?

As-bearing or arsenate-bearing pyromorphite would be much better.
The modifiers -ian, -oan etc. have long been discouraged officially.

OK, thanks!

It’s very surprising it’s missing, I thought Bunker Hill pyromorphite is usually designated “Arsenian”? 
I did remove Germanate-pyromorphite is it’s a distinct compound not a variety ( though I sometimes wonder if synthetic compounds belong here?)

I was actually glad to hear Uwe's answer because I still say "endlichite".
