On April 17, 2026, the Mount Siguniang National Nature Reserve Administration Bureau sent a letter of thanks to the School of Earth Sciences and Engineering (SESE) at Nanjing University, expressing heartfelt gratitude and high respect for the outstanding contributions made by the scientific research team led by Academician Xu Zhiqin during the application process for the Mount Siguniang UNESCO Global Geopark.
In 2026, Mount Siguniang was successfully approved as a UNESCO Global Geopark. This major achievement not only marks another significant outcome in the protection and utilization of world-class geological heritage in China, but it also fully reflects the academic strength and sense of responsibility of the SESE in serving the strategic needs of the nation and promoting the protection of geological relics, popular science education, and sustainable development.
Since the launch of the Mount Siguniang Global Geopark application in 2022, SESE proactively responded by assembling a high-level scientific research team led by Academician Xu Zhiqin, with core members including Professor Shu Liangshu, Professor Hu Xiumian, Professor Zhu Wenbin, Professor Wang Qin, Professor Li Guangwei, Associate Professor Wang Guoguang, Dr. Zheng Bihai, and Dr. Gao Jianguo. The team traveled to the high-altitude region of Mount Siguniang to carry out systematic and intensive research. With the Academician personally leading the way, team members overcame extreme natural conditions such as severe cold, oxygen deficiency, and complex terrain to root themselves on the front lines and carry out high-intensity scientific research and technical support work.
Centering on the core requirements for declaring a Global Geopark, the Nanjing University team collaborated closely with units such as the Sichuan Institute of Geophysical Survey to systematically execute key tasks, including geological heritage verification, scientific value promotion and evaluation, geological evolution model construction, and the preparation of application materials. From the precise analysis of stratigraphic sections to the comprehensive study of regional tectonic movements, and from the systematic reconstruction of the geological evolution process to the deep excavation of popular science value, the team comprehensively extracted the geological landscape features of Mount Siguniang, including its "Xikang-type folds," "turbidite flysch formations," "glacial geomorphology," and "extremely high mountain peaks." They also highlighted Mount Siguniang's unique geological significance and international value in the geological evolution of the eastern margin of the Qinghai-Tibet Plateau. Simultaneously, strictly aligning with international evaluation standards, the team repeatedly polished the application texts and argumentation systems, completing multiple rounds of written and on-site evaluations and defenses with UNESCO international experts at a high level of quality, providing authoritative, systematic, and reliable technical support for the project's successful approval.
The letter of thanks highly praised the college team's scientific spirit of "braving severe cold, risking oxygen deficiency, and battling hardships and dangers" and their rigorous and realistic work style. It recognized that the team, with their striving for excellence in scientific research and outstanding professional capabilities, fully demonstrated the scientific value of Mount Siguniang's geological heritage, powerfully driving the successful completion of the application process.
The successful inscription of Mount Siguniang as a Global Geopark is an important milestone in China's advancement of ecological civilization construction and the strengthening of systematic natural heritage protection. It is also a vivid practice of Nanjing University deepening school-local cooperation and promoting the integration of science and education. The successful implementation of the project not only provides scientific support for the protection and management of regional geological relics but will also further promote geoscience popularization education and green sustainable development, injecting new momentum into the high-quality economic and social development of the local area.
For a long time, SESE has consistently adhered to the principle of "writing papers on the vast land of the motherland," actively aligning with major national needs, continuously leveraging the advantages of geoscience disciplines, and achieving a series of influential results in fields such as geological heritage protection, resources and environmental research, and science communication. Helping Mount Siguniang successfully attain Global Geopark status this time fully demonstrates the comprehensive strength of the school in serving national strategies and leading disciplinary development.
Facing the future, SESE will take this as an opportunity to further deepen cooperation with important geological heritage sites like Mount Siguniang, continuously strengthen the collaborative innovation of basic and applied research, and promote the translation of geoscience achievements into ecological protection, popular science education, and sustainable development, contributing even greater strength to the construction of China's global geopark system and a Beautiful China.

Letter of Thanks
Dear Academician Xu Zhiqin and the team from the School of Earth Sciences and Engineering, Nanjing University (Professor Shu Liangshu, Professor Hu Xiumian, Professor Zhu Wenbin, Professor Wang Qin, Professor Li Guangwei, Associate Professor Wang Guoguang, Dr. Zheng Bihai, Dr. Gao Jianguo, etc.):
Thank you for your hard work!
On the occasion of Mount Siguniang's successful approval as a UNESCO Global Geopark, with unparalleled excitement and gratitude, we extend our most sincere thanks and highest respect to you!
Since the comprehensive launch of the Mount Siguniang Global Geopark application work, you and your team headed to the front lines of research and traveled far to the plateau, taking root in the high-altitude scenic area to form a highly capable and efficient technical team. You braved the severe cold, risked oxygen deficiency, and battled dangers, traversing the snow peaks, canyons, and rock formations of Mount Siguniang to systematically complete core tasks such as geological heritage investigation, scientific value evaluation, geological evolution model construction, application material compilation, and defense with international experts; you gave up holiday rest, worked overtime, and stayed up all night to polish details, ensuring with ultimate rigor that every document and every piece of reasoning could withstand international evaluation; from stratigraphic section analysis to tectonic movement research, and from geological evolution model construction to popular science value extraction, you comprehensively distilled the unique value of Mount Siguniang in the geological evolution of the eastern margin of the Qinghai-Tibet Plateau, allowing the scientific charm and international value of this geological heritage to be fully demonstrated, and providing authoritative and comprehensive technical support for the application.
In 2026, the good news arrived, and Mount Siguniang was formally approved as a Global Geopark with an excellent score. This successful application is a milestone in the protection and development of Mount Siguniang, as well as a model of school-local cooperation and the integration of science and education. Your outstanding contributions will inject lasting momentum into geological heritage protection, popular science education, and sustainable development. Every inch of rock and every landscape is engraved with the footprints of your scientific exploration.
Once again, we extend our highest respect and most heartfelt thanks to Academician Xu Zhiqin and all team members! We hope that in your future work, you will continue to support Mount Siguniang, care for Mount Siguniang, and devote your affection to Mount Siguniang as always, joining hands to achieve the high-quality protection and sustainable development of the Mount Siguniang Global Geopark! We sincerely invite you to come back to Mount Siguniang often, to visit this magnificent landscape engraved with your scientific footprints!
