Dmitry Y. Tonkacheev (born. 19/03/1990). Moscow, Russian Federation

I was interested in mineralogy since I was ten. My first rock in the collection was obsidian. Now, I perform some research in the field of spectroscopy of minerals (EPMA, LA-ICP-MS, and XAS) and experimental petrology. I also do some works in the field of ore mineralogy.

Education

2011-2013 Ms.Sc. Lomonosov Moscow State University. Geological department. Laboratory of mineralogy.

2007-2011 B.Sc. Lomonosov Moscow State University. Geological department. Laboratory of mineralogy.

Research interests

Mineralogy of ore deposits, spectroscopy of minerals, LA-ICP-MS, EPMA, XAS, rare minerals, crystal chemistry
