Thank you very much!

Although the mineral is from the Kola Peninsula, the Russians who described it named it in honor of a real live German crystallographer and mineralogist, Wulf Helmut Heinz Depmeier (born 1944), Professor of Mineralogy and Crystallography at Christian-Albrechts University in Kiel. He is a well known specialist in crystal chemistry of the sodalite-cancrinite family of minerals and structurally related synthetic compounds.

Anyway, I thought this was an admirable example of absence of nationalism, and I hope a German will name a mineral after a Russian soon!

I have added the information to the mineral data

me too!

Thanks a lot

Hallo,


Ich kann alfredo nur Zustimmen Prof. Depmeier ist eine wirklich große Persönlichkeit. Ich habe einige seiner Vorlesungen gehört und eine meiner Diplomprüfungen bei ihm abgelegt. Immer fair, immer offen für die Studenten. Ein großer Fachmann auf seinem Gebiet. Er arbeitet eng mit der Universität St. Petersburg zusammen.

Alfredo: I do absolutely agree with you. He is one of the most honorable persons I know. I had heard some of his lectures and can tell that he always do what he can for the students. He works together with St. Petersburg University, Russia.

Glück Auf!/Regards,
Sebastian Möller

"Anyway, I thought this was an admirable example of absence of nationalism, ..."

Tillmannsit ist auch so ein Beispiel (von russischen Wissenschaftlern nach einem verdienten deutschen, in Österreich arbeitenden Kristallographen benannt).
