摘要

For candidates of UNESCO Global Geopark, how to carefully select the types of geological heritage to ensure their geological diversity, and how to fully demonstrate the international value of these geological heritage have a crucial impact on whether they can successfully join the global geoparks network. Kanbula Geopark is located in Huangnan Tibetan Autonomous Prefecture of Qinghai Province of the People’s Republic of China, and the only geopark where the Tibetan people are the main inhabitants. The Geopark was defered as a UNESCO Global Geopark for a maximum duration of two years and the first delayed geopark in China because that it was not sufficiently demonstrated the international geological significance of the key geological sites. According to the newly issued Guidelines for the assessment of the international significance of geological heritage in UNESCO Global Geopark applications (Document code: SC/EES/2023/UGGp/4), the Kanbula Geopark was redefined the selection principle of the geological heritage and discussed the international value of its geological sites, and was included in the Global Geoparks Network in September 2024. 45 geological sites were selected to reflect the diversity of geological heritage in the region. By comparing with the geological heritage of the existing global geoparks and analyzing the scientific research value of the geological heritage based on scientific publications, four geological sites of international significance have been recongised within the Kanbula Geopark. Hongtushan unconformity between the Cretaceous Hekou Group and the Triassic Longwuhe Group represent the closure-collision orogeny of the Paleo-Tethys Ocean and the subsequent weathering and erosion during the Late Triassic to the Jurassic. Longwuhe Triassic section, one of the most important section of the Triassic successions, provides key sedimentary evidence that helps deciphering the evolution of the Paleo-Tethys Ocean during the Triassic. Maixiu Mesozoic volcanic group recorded the tectonic environmental changes before and after the closure of the Paleo-Tethys Ocean. The landslides on the south bank of the Yellow River are closely related to the uplift of the Qinghai-Tibet Plateau and the incision of the Yellow River since the Quaternary.
