Synopsis top ↑

This volume has developed from an excursion guidebook that was initially prepared for the international workshop “Geodynamics and Metallogeny of Mongolia” that has been held in Ulaanbaatar, 30 July - 1 August 2003, with a one-week follow-up expert field trip to Oyu Tolgoi and some adjacent deposits and exploration targets in the South Gobi. Increasing interest in the geology of Cu-Au and other mineral deposits of Mongolia has encouraged the editors to produce the present up-dated, largely revised and expanded book that includes supplementary chapters on other famous deposits such as the giant Erdenet Cu-Mo porphyry system and the Boroo gold deposit. This monograph represents simultaneously the guidebook of the SEG-IAGOD field trip “Copper and Gold Deposits of Mongolia” visiting the Oyu Tolgoi, Erdenet and Boroo deposits (14-16 August 2005). The trip took place as pre-conference excursion related to the 8th Biennial SGA Meeting in Beijing/China (18-21 August 2005).
We hope that these data published under the auspices of the IGCP-473 project will prove helpful in understanding the geology and metallogeny of Mongolia.
