China's Geological Heritage Sites Total Reaches 13 with New Additions

Three locations in China have been added to the International Union of Geological Sciences (IUGS) list of Geological Heritage Sites. Announced in Portugal as part of the third group of 100 such designations, these additions bring China's total count to 13. The new sites comprise the Xianshuihe Fault in Sichuan Province, the Middle Jurassic Dinosaurs of Yunyang in Chongqing Municipality, and the Triassic Dabie Ultrahigh-pressure Metamorphic Belt in Anhui Province. Together, they offer vital records of the Earth’s 4.6-billion-year history and the geological evolution of the planet.

Included within the tectonics category, the Xianshuihe Fault is recognized for its international scientific importance. It stretches for approximately 400 kilometers along the eastern edge of the Qinghai-Xizang Plateau, where well-preserved landforms and clear traces of seismic activity remain visible. These features provide a window into the mechanics of crustal deformation and fault activity, helping researchers understand the forces that sculpt the Earth's surface. Studies by various geological institutes identify this as one of the most active intracontinental fault zones in the world, serving as a key natural laboratory for the study of earthquake processes.

Another new addition is the Yunyang Dinosaur Fossil Site Museum in Chongqing Municipality, which preserves a significant collection of dinosaur remains from the Middle Jurassic period. This site offers a unique perspective on prehistoric life within the region. Joining it on the list is the Triassic Dabie Ultrahigh-pressure Metamorphic Belt in Anhui Province. This location broadens the geological diversity of the IUGS registry by showcasing rare formations that illustrate the intense pressure and heat involved in high-pressure metamorphic processes.

Adding these locations to the global list highlights the role of China's geological landscape in international science and points to the necessity of preserving them for future study. These sites provide a foundation for researchers to examine the ancient history of the Earth and the various processes that have shaped it over millions of years. Beyond their scientific value, they act as important resources for public education and for building a deeper understanding of geological science.

The recognition of these sites emphasizes the broader need for the conservation of geological heritage. As the world pays closer attention to environmental shifts, these locations become increasingly relevant for understanding natural disasters and climate patterns. The IUGS remains committed to advocating for the protection of such sites while working to expand the global registry and encourage international partnerships in geological research.
