INVITATION TO ATTEND
The 2004 Interim IAGOD Conference presents an opportunity to bring together the geologists from all over the world in Vladivostok, one of the major cities of the Russian Far East. This area known for its tremendous mineral wealth ranks among the most geologically interesting territories of the Russian Federation, whose geological history has been conditioned by the interacting Pacific and Eurasian plates. Ancient geological structures of Asia and young structures of the Pacific Belt, that is the transit zone from continent to ocean, are present here.
Specific geological structure of the Russian Far East governed its unique mineral deposits.
The territory is abundant in granitoids of various genesis, age, and composition with the related deposits of tin, tungsten, gold, lead, zinc, fluorite, and some rare-earth and other elements.
The Southeast (Primorye) is the most populated, and best explored and economically developed area of the Russian Far East. 40% of Russian zinc and lead is mined there. «Dalpolimetall» Mining Company is the major business operating the skarn-polymetallic deposit of the Dalnegorsk ore district, famous by its great mineral resource and magnificent crystal druses. «Bor» Mining Company operating boron-silicate deposit produces 100% of Russian boron. Its host ore bodies, pyroxene-amphibole skarns beautiful in color and pattern, are used as gem stones known as «Primorsky malachite». «Khrustalnaya» Mining Company operating the Iskra deposit provides about 20% of Russian tin. «Primorskaya» and «Lermontovskaya» Mining Companies together produce 40% of Russian tungsten mined at the major skarn-scheelite deposits Vostok-2 and Lermontovka, North Primorye. To the south of the Vostok-2 deposit there is another tin-tungsten deposit with rare-earth elements, the Tigrinoye. This deposit, completely explored and prepared for operation, is related to granites of lithium -fluorine type. Further to the south, just on the bank of the Ussurka River there is the Zabytoe deposit of the same type, famous by big blue topazes.
Unique fluorite deposits rich in rare-earth elements, the Voznesenka and Pogranichnoye, of the western Primorye are related to similar granites. They are operated by «Yaroslavskaya» Mining Company producing 80% of Russian fluor spar.
Annually Primorye produces 11 000 000 t of brown and hard coal and much building materials for two local cement factories. The territory is famous for its underground mineral wells and marine mud used for health care purposes in multiple medical centers and resorts, including «Shmakovska» the major Russian resort. Placer gold is produced in small amounts in black schists at the Glukhoe» deposit. This gold-bearing area is promising for sapphires.
The participants of the conference are also invited to visit the major tin deposits of the Komsomolsk ore district (southern Khabarovsk Territory, the city of Komsomolsk-on-Amur). «Solnechnaya» Mining Company operating these deposits produces about 30% of Russian tin. In addition to tin, they extract tungsten, copper, zinc, lead, and gold.
Over 700 km to the north of Khabarovsk there is another unique Pt and Au deposit, the Konder, whose placers resulted from the destruction of zoned alkaline ultrabasic Pt-bearing intrusive are crossed by dikes of different composition. In its bedrock and placers gold is associated with platinum. Silver, tin, copper, nickel, antimony, and bismuth minerals also occur.
The proposed program comprises pre- and post-conference field tours, scientific and social programs, rock, map, and publication displays, and trade exhibition. The program presents an opportunity for delegates to visit several famous large, and unusual ore deposits of the Russian Far East and the Pacific Rim.
