Speleological discoveries contributed by the Institute of Geology

A few days ago, members of the Czech-Polish speleological expedition returned from China (Xiaonanhai area near Hanzhong in Shaanxi Province). The expedition was organized by the Czech Speleological Society and the Institute of Geology of the CAS. The speleologists continued in the survey and documentation of karst phenomena they have been discovering since 2016. In total, about 4 km of new cave spaces were discovered using rope techniques and boats, including large underground halls. Several new sedimentary phenomena have been noted as a part of the documentation and will be the subject of further research.
