Description

Niedermayrite from Laurani is a new find from this mine. Material was analysed. There might be more interesting minerals on the specimen. Sometimes filigrane high lustrous needles occur, which could either be a Cd rich serpierite or a separate species. As the EDS results are promising, I will do some further investigations.
