Scientist from the Trofimuk Institute of Petroleum Geology and Geophysics SB RAS made presentations at the First China-Russia Conference on Multi-sphere interaction and its impact on resources in Northeast Asia. The event was held in Hulun-Buir, Inner Mongolia Autonomous Region (PRC), from August 12 to 16, 2025.
Besides Chinese representatives, the organizing committee of the symposium included Russian scientists, among them Vyacheslav N. Glinskikh, Director of IPGG SB RAS, corr. member of the Russian Academy of Sciences. Other conference presenters were affiliated with major universities and research centers of China, as well as institutions of the Siberian Branch of the Russian Academy of Sciences and the Far Eastern Branch of the Russian Academy of Sciences.
Russian scientists at the conference
Presentations of researchers from IPGG SB RAS covered many specific fields of research of the Institute. Thus, Dmitry Grazhdankin, DSc (geol-mineral.), head of the Laboratory of Precambrian Paleontology and Stratigraphy, expressed the view that intense continental chemical weathering caused the Ediacaran Shuram anomaly, the largest carbon isotope excursion of the entire marine sedimentary record. In support of his hypothesis, he demonstrated fossil evidence from Southern Siberia and Southern China.
A comprehensive presentation was given by Mikhail Fomin, IPGG SB RAS deputy director for science, PhD (geol.-mineral.) on behalf of a large team of IPGG researchers and dedicated to high-carbon carbonate-clay-siliceous oil-prone marine source formations from the Lena-Tunguska, Lena-Vilyui and West Siberian oil and gas provinces. The study of sediments that can be both source rocks and producing reservoirs, is a highly topical problem both in Russia and China.
Sergey Yaskevich, Ph.D., sr research scientist at the Laboratory of Deep Seismic Problems, presented a geophysical monitoring program for geologic carbon dioxide sequestration sites. Olga Izokh, PhD (geol.-mineral.), sr research scientist at the Sedimentology Laboratory, demonstrated isotopic and geochemical evidence of global changes in the marine ecosystem during the earliest Emsian.
The presentations of researchers from IPGG SB RAS aroused great interest from their Chinese colleagues. Some representatives from Russian and Chinese academies of sciences that participated at the conference have already discussed prospects and mechanisms for further fruitful cooperation.
During the post-conference excursion, the participants examined interesting geological objects in the vicinity of Hulun Buir
