TAILIEUCHUNG - Geological values of lava caves in Krongno Volcano Geopark, Dak Nong, Vietnam

The paper presents the initial results of the study of volcanic cave system and its typical formations in Krongno Volcano Geopark (KVG), Dak Nong, Vietnam. The volcanic caves have been discovered since 2007, under UNESCO sponsored the scientific project, are seen as unique geological heritages. The collaborative surveys and studies between Vietnamese geologists and the members of the Non-Profit Organization, Vulcanospeleological Society of Japan have discovered and surveyed 45 caves, and detailed mapping 20 caves. | Vietnam Journal of Earth Sciences 40 4 299-319 Doi 0866-7187 40 4 13101 VAST Vietnam Academy of Science and Technology Vietnam Journal of Earth Sciences http jse Geological values of lava caves in Krongno Volcano Geopark Dak Nong Vietnam La The Phuc1 Hiroshi Tachihara2 Tsutomu Honda2 Luong Thi Tuat1 Bui Van Thom3 Nguyen Hoang3 Yuriko Chikano2 Katsuji Yoshida2 Nguyen Thanh Tung4 Pham Ngoc Danhs Nguyen Ba Hung1 Tran Minh Due1 Pham Gia Minh Vu1 Nguyen Thi Mai Hoa1 Hoang Thi Bien6 Truong Quang Quy7 Nguyen Trung Minh1 1 Vietnam National Museum of Nature VNMN Vietnam Academy of Science and Technology VAST 2NPO Vulcano-Speleological Society VSS Japan 3Institute of Geological Sciences IGSVN Vietnam Academy of Science and Technology VAST 4International Tour Guide Dak Nong Province Vietnam - VNMN s Collaborator 5Department of Science and Technology of Dak Nong Province Vietnam 6Co Ltd.

The volcanic caves have been discovered since 2007 under UNESCO sponsored the scientific project are seen as unique geological heritages. The collaborative surveys and studies between Vietnamese geologists and the members of the Non-Profit Organization Vulcanospeleological Society of Japan have discovered and surveyed 45 caves and detailed mapping 20 caves. Using a complex of adequate methods especially Remote Sensing image interpretation method Surveying and mapping lava cave method K Ar dating isotopic analytical method and Current methodology the studies aim to affirm endogenous origin of the lava cave system the formation mechanism as well as the typical formations of the caves. Up to date the lava caves and .
