Tsumeb - Tsumgallite on a specimen of a good friend!

This weekend three of my friends visited me for some analytical work on their self collected and collection material.

One of them had an old Tsumeb sample hosting filigrane silky masses on germanite renierite matrix. Not very beautiful, but obviously interesting stuff.

EDS analysis gave a single gallium peak. As söhngeite does not fit the habit, we concluded tsumgallite.

Raman analysis should be done later, to collect a spectrum of tsumgallite.

If you should ever consider to analyse material from your findings you can contact me via joydesor@gmail.com.

We have also a new high resolution Raman spectrometer with a green laser. This allows in-situ measurements of very limited amount of material down to 20µm.
