The 17th workshop on the joint project of five countries “Deep Processes and Metallogeny of Northern, Central and Eastern Asia”, organized by the Ministry of Mining and Heavy Industry of the Republic of Mongolia, was held on 4-10 August 2019 in Ulan Bator in accordance with the Minutes of the 16th workshop (Jeju Island, Republic of Korea, 2018). Delegations were represented by A. Delgersayhan (Mongolia), T.N. Zubova (Russia), Ding Xiaozhong (China), Paul Hong (South Korea), M.M. Tnaliev (Kazakhstan).
Participants at the 17th workshop
Within the workshop framework, presentations were made on the work progress and results achieved by agreements at the past meeting on Jeju Island, Republic of Korea (2018). In total, 27 presentations were made, discussed by more than 40 scientists from five countries.
Presentation by I.I. Pospelov
Presentations by FGUP “VSEGEI” employees (T.N. Zubova et al.; I.I. Pospelov; G.A. Babin et al.; V.V. Snezhko et al.; I.V. Kudryavtsev et al.; E.D. Milshtein et al.; A.G. Pakhalko et al.) reflected the current state of the international project and its development prospects, modern views on the tectonics and metallogeny of Northern, Central, and Eastern Asia, the need for further integration of isotopic data and geological mapping, the use of materials of tectonic stratigraphy and palaeogeodynamic reconstructions, as well as deep structure data for modern tectonic constructions (Barents-Kara region, Amerasian Basin, and East of Russia).
Based on the workshop results, Minutes were signed with a number of key decisions on the international project “Deep Processes and Metallogeny of Northern, Central, and Eastern Asia”:
1. To approve the efforts and preliminary results of the Russian and Mongolian working groups for a detailed study of the tectonic, palaeodynamic, and metallogenic features of the corresponding parts of the joint project area for the compilation of “Maps of accretion-collision tectonics and related mineral deposits”, and “Map of rift-plume tectonics, magmatism, and related mineral deposits”; recommend: (1) to create working groups on the above topic, (2) for Chinese, Kazakh and Korean working groups to join the compilation of tectonic/metallogenic maps and present the first fragments of both maps for their areas at the next workshop.
2. To prepare and publish explanatory notes for maps of the Atlas of Northern, Central, Eastern Asia and adjacent areas (geological, metallogenic, map of energy resources) at 1: 2,500,000 scale and issue the second edition of the Explanatory Note to the tectonic map by the IGC-36.
3. In order to develop the topics of isotope geochemistry and petrology of geological complexes of Northern, Central, and Eastern Asia, to recommend the following: (1) by February 2020, exchange of information on technologies for storing and transmitting isotope geochemical data, including a list of web services used and their brief characteristics; description of the structure of the isotope geochronological database and basic terminology; (2) by the 18th workshop, the Russian working group should prepare proposals to shape up a single resource of isotope geochemical data of the participating countries, based on the recommendations of the DDE project.
4. By the end of 2019, to exchange primary geochemical data to assess the possibility of compiling a set of geochemical maps with a single database on the project area. The Chinese working group begins to compile geochemical maps after data exchange.
5. To agree with the proposal of the Russian working group to prepare a digital presentation with the project results “Deep Processes and Metallogeny of Northern, Central, and Eastern Asia” by the IGC-36 in India; submit prepared materials for approval and supplementing by other participating countries in December 2019.
As a result of discussions by the workshop participants, it was decided to hold the next 18th workshop on the joint international project in June-July 2020 in Russia. Delegations from Russia, China, Kazakhstan, and the Republic of Korea expressed gratitude to the Mongolian side for organizing the 17th workshop in Ulan Bator, Mongolia, at an exceptionally high level.
At the workshop closing ceremony, four representatives of the Russian delegation Dr. I.I. Pospelov, Dr. S.P. Shokalsky, Dr. E.D. Milshtein, and Dr. G.A. Babin were awarded the state awards “Honorary Geologist of Mongolia” for their services in geology. The certificate of honour of the Ministry was handed to Ms. N.I. Kuba.

At the end of the workshop, a field trip was conducted with a visit to geological targets and deposits within the western part of the Mongol-Okhotsk belt:
Baga-KhairKhan Tungsten Mine
Zones of gold mineralization at the contact of volcanic-sedimentary Early Mesozoic rocks and granites of the Ikh-KhairKhan massif
Granites of the Ikh-KhairKhan massif
Bald Hill (Khalzan Unduur) Gold Epithermal Field
