MineralsAxinite-(Mn)

Mindat gives the type locality as Franklin, NJ. Fleischer lists it as St. Andreasberg, Germany.
Which one is in error?

Neither is necessarily an "error". With 19th century minerals, before any official approval process existed for new species, a species might have been mentioned several times from different places with varying degrees of descriptive precision. So which one is the "type locality"? The place where the name was first used? The place from which an analysis was first published, without naming it? The place from which a full description was first published?

I haven't specifically studied the history of Axinite-(Mn), but we can point out numerous old pre-IMA species where the concept of "type locality" has only a rather fuzzy meaning. This situation continued for many minerals until the IMA approval procedures came into effect in the late 1950s, after which type locality became the place the type specimen came from. For many 19th century minerals no type specimen exists. In modern mineralogy the type specimen is important, while type locality has more importance for collectors than mineralogists.

The IMA list has Germany and gives the ref.

On Mindat, St Andreasberg just lists “axinite group” with no reference so this may need some work. The axinite-(Mn) page pointedly says all the descriptive work was done on Franklin material, from as early as 1891.

I suspect Franklin gets the nod... I'll dig out the articles, we should have them...

Can I upload pdfs to the 'click here to add a photo or video' tab?
