System:Hexagonal
Name:For Dr. I. Vavřín, analytical chemist at the Czech Geological Survey and one of the discoverers of this mineral. Dr. Vavřín earned his CSc (Ph.D.) from the Academy of Science, Prague. He is an economic geologist with areas of interest in geochemistry and the environmental aspects of mineral deposits; metallogeny of black shale formations; precious metals in anoxic environments and various types of ore deposits and the roles of organic matter in the genesis of mineral deposits. He received the Paul Ramdohr Medal from the Society of Geology Applied to Mineral Deposits. He served as: 1997-1998 Vice-President, SGA (Society for Geology Applied to Mineral Deposits); 1997 - to date Executive Secretary of SGA; 2000 - to date Member, Czech Geological Committee; and, 2001-2002 Chief Editor, Bulletin of the Czech Geological Survey.
