Sanqing Mountain Geopark is renowned for its rich and diverse geological relics and unique geohistorical value. On the aesthetic and scientific levels, the park features magnificent natural landscapes shaped by geological structures and biological formations of outstanding and universal value. From scientific and conservation perspectives, it preserves structural units with significant geological and geomorphological importance, as well as habitats of rare and endangered species. At the same time, in multiple dimensions including science, conservation, and aesthetics, Sanqing Mountain showcases highly representative natural landscapes and natural zones.

As an outstanding example of a key stage in the history of Earth's evolution, the geological relics of Sanqing Mountain record ongoing geological processes, landform evolution, biological evolution, and the harmonious interaction between humans and nature. The park not only contains unique, rare, or marvelous natural phenomena and landforms but also preserves habitats of rare or endangered species, presenting a rare natural aesthetic value. These precious geological heritages give Sanqing Mountain unique and significant global importance in scientific, educational, and aesthetic fields, making it an important base for earth science research, natural exploration, and science education.

Sanqing Mountain is located at the junction of the Yangtze Plate and the Huaxia Plate, with well-developed strata exposed from the Mesoproterozoic to the Quaternary, systematically recording the geological evolution and major geological events of the region over the past billion years. Research on the sedimentary strata in this area is crucial for understanding the formation and evolution of the junction between the Yangtze and Huaxia plates and is currently one of the hot research topics in the Chinese geological community.

Since the Cambrian, the strata of various periods in the Sanqing Mountain area have preserved abundant paleontological fossils, with clear evolutionary sequences. The Early Paleozoic is dominated by trilobites, conodonts, and brachiopods; the Late Paleozoic primarily features dragonflies, brachiopods, corals, and plant fossils; the Mesozoic is represented by bivalves, plants, leaf stems, and dinosaur fossils. During the Late Cretaceous, the Xinjiang Basin, where Sanqing Mountain is located, was a habitat for dinosaurs, leaving behind a large number of dinosaur eggs and some skeletal fossils. These findings hold important scientific significance for studying biological evolution, paleoenvironment changes, ancient climate, and paleoecology in southern China.
