Aleksandr Vasil’evich Kalugin (1857–1933) and former kaluginite (now jahnsite-(CaMnMg))

Abstract

Aleksandr Vasil’evich Kalugin was a major practical mineralogist and compiled magnificent mineralogical collections from the Ural samples. While working at the Ural Mining Institute, he trained a whole galaxy of mineralogists and donated his unique collection of minerals, on the basis of which the Ural Geological Museum was created in 1937. In honor of him in 1983 B. V. Chesnokov named a new mineral – kaluginite, which was almost immediately rejected by the International Mineralogical Association. At the moment it turned out that kaluginite is jahnsite-(CaMnMg).
