Mineralogical Classificationdifference between pyromorphite and polysphaérite

21st Jun 2005 10:49 UTCjma

Dear all,



what is the composition difference between pyromorphite and it is polysphaérite variéty?

.... Calcium content?

21st Jun 2005 11:27 UTCPete Nancarrow

"Polysphaerite" is an obsolete term which has been used to refer to the calcian variety of pyromorphite . It may appear as the mineral name on old specimen labels, but it is not a mineral species. Modern terminology would be to call it calcian pyromorphite.

Polysphaerite entry needs to be merged into Calcian Pyromorphite and be made a synonym.



I'll need to do this manually later to get the photos and localities to move correctly.
