Name:
Named in honor of Ivan Vavřín (1937-), analytical chemist at the Czech Geological Survey and one of the discoverers of the mineral, in recognition of his investigations of tellurium minerals and significant contributions to research on Cu-Ni sulfide deposits. He earned his CSc (Ph.D.) from the Academy of Science, Prague.
Unique combination of elements. To date, this species is still extremely rare.
Properties were determined from synthetic material.
Note: chemically identical phase, previously coded as UM1974-22-Te:NiSb in the Valid Unnamed Minerals list, was reported from Southwestern China.
