my country has added 3 new world geological heritage sites. What is their secret?

The reporter learned from the China Geological Survey of the Ministry of Natural Resources today (11th) that the International Union of Geological Sciences recently announced the third batch of 100 world geological heritage sites in Portugal, and three places including my country's Xianshui River fault were "on the list."

The geological heritage sites selected this time are the Xianshuihe Fault, the Yunyang Middle Jurassic Dinosaur Fossil Group and the Triassic Ultra-High Pressure Variable Zone in the Dabie Mountains. So far, the number of geological heritage sites in my country selected for the World Geological Heritage Sites list has increased to 13.

Geological heritage sites are engraved with the earth’s 4.6 billion years of vicissitudes. They are precious, non-renewable natural historical materials and are the “code books” that unlock the earth’s history. Among the three newly added geological heritage sites, the Xianshuihe Fault was selected into the "structural geology" category, and is included in this batch of lists with world-renowned structural sites such as the New Zealand Alps Fault and the San Andreas Fault in the United States, demonstrating its outstanding international geological scientific value. The Xianshuihe Fault is located in western Sichuan and the eastern edge of the Qinghai-Tibet Plateau, stretching for about 400 kilometers. The fault landforms and earthquake relics preserved here provide an important window for understanding fault activity, crustal deformation, and the shaping process of the surface landscape. The scientific research team of the Institute of Geology under the China Geological Survey has been conducting research on the Xianshuihe fault for a long time, revealing that it is not only one of the most active fault zones within the continent in the world, but also a special fault zone with long-term creep and stick-slip coexistence. It is a natural laboratory for studying earthquake processes and chain-generated geological disasters within the continent, and provides important scientific basis for earthquake prevention and disaster reduction.
