Hi all,

I have just received this specimen and would like to check the the location details.

The label with the specimen states:

'strontianite - Sibernaal, Harz Mts, Germany.'

Can anyone confirm this?

Thanks in advance.

Phil

"Sibernaal" does not produce any hits in Europe in a Mindat locality search. However, there is a Silbernal in Bad Grund, Harz, Lower Saxony, Germany. Mindat does not have a species list for Silbernal itself, but the list for Bad Grund includes strontianite. So this is at least reasonable.

Your specimen does not appear distinctive, and in fact it might be aragonite or some other mineral. It would be good to test for carbonates with warm vinegar or dilute HCl, and a flame test would establish the presence of strontium by flame color.

So your specimen cannot be attributed to Silbernal or Bad Grund with certainty, but it appears to be a reasonable possibility, especially if you can verify that it is strontianite.

Pete was on the right way:

The name is not "Sibernaal", but "SiLbernaal". Silber is the German name for silver and the word Silbernaal means silberner nagel (silver nail). Silbernaal was the name of a mining area and a miner village near Bad Grund, Harz Mountains.

Hope I could help :-)

Thanks for the suggestions.

I dont think the label can add anything because it is from an English dealer but it is possibly pre-1970's IF the 12/6 seen on it refers to the original purchase price paid (12 shillings and 6 pence pre-decimal coinage?). I will attach a label picture.

A quick fizz test shows good effervescence with dilute HCl and so carbonate. No flame test yet but will try to get one done and will post any results.

Phil

Thanks, Tobi. Being German, you would know better than I, for whom german is a distant second language. I thought of Silbernaal = Silbernagel, but Mindat has it Silbernal, with one "a". Mindat is pretty reliable, but I guess they make mistakes now and then....
