caves in Krong No area, Dak Nong province were discovered in 2007, detailed surveyed,
measured and mapped from 2012 to 2017, then have been studied in the
multidisciplinary fields (geological heritage - biodiversity - cultural
heritage and environmental bio-geochemistry) since 2017 to present. In term of geology, Krong No volcanic caves are primary/endogenic
caves, otherwise, their entrances are mainly secondary/exogenous origin.
Interior formations in Krong No volcanic caves are plentiful and diverse. They
are authentification evidences for the primary/endogenic origin and the formation
mechanism of volcanic cave due to gas escape - volume shrinkage of lava flow.
Biologically, Krong No volcanic cave is the habitat of many species, including
endemic species only found living there. In term of cutural heritages: Krong No
volcanic caves contain archaeological relics, especially prehistoric human
remains, which are very rare in The Central Highlands, as well as in volcanic
caves of the world. The bio-geochemistry environment in Krong No volcanic caves
is distinctive favourable for preservation of organic materials, animal bones
and teeth, as well as prehistoric human remains. The global outstanding value
of Krong No volcanic cave system was established in all three fields of
geological, biological and cultural/prehistoric archaeological heritages. They
all have been comprehensively studied, established for conservation, meeting
community’s various needs and tourism exploitation, contributing to
socio-economic sustainable development. Some initial typical research results
on heritage in Krong No volcanic caves of Dak Nong UGGp will be introduced in
Keywords: volcanic cave, geological heritage/geoheritage, prehistoric relic,
