About

Avtandil Okrostsvaridze graduated from Tbilisi State University Geology department in 1978. In 1983-1985 he became a postgraduate student at the Cambrian Geology Institute (Petersburg) of the Academy of Sciences of Russia. Defended his PhD dissertation on “Petrology of Abkhazian Paleozoic Granitoids and Migmatites” in1987 and postdoctoral dissertation on Petrology of Hercynian Granitoid Series of the Greater Caucasus in 1995. In 1996-1999 worked on Dalhousie University (Canada) project Mantle-Crust Interactions and Granitoid Magmatizm.  In 1997 was awarded the status of the first discoverer of Hokrila Gold-Anthymonite ore manifestation by the commission of the first discoverers of the Geological Department of Georgia (P.K.02). He worked as scientific vice director of the Geological Institute of the Georgian Academy of Sciences in 2002-2006. For the monograph “ Hercynian Granitoid Magmatizm of the Greater Caucasus “ he was awarded A. Janelidze Scientific Prize in 2008. In partnership with other scientists, he located Hokila ore-bearing valley in 2009. In 2008-2010 he was a coordinator in NATO project: Volcanic Safety  and  the Protection  Measures on the  Georgian Segment  of the Georgian  Segment of the  Caspian Oil and Gaz  Pipeline”.  In 2010-2012 he was the  Scintific leader of the Georgian National Scientific Fund  project “Evaluation  of Gold  Potential    in the Kaxeti Segment of the Greater Caucasus“.   Fulfilling the project, he together with other project members, discovered Thorium significant ore occurrences on Kakheti  segment of the Greater Caucasus.    He has worked at Ilia State University since 2010. Now he participates in several international projects, among them in UNESCO IGCP #610 project: “Environmental Change  and  Human  Response  during Quaternaty”.  He organized its first plenary session at Ilia State University in 2013.  He has supervised three  PhD dissertations.  He has published more than 180 scientific papers.
