Geological Values

  • Geological value 01

    The professional education center of the entire geological era!

    The mudeungsan area contains rocks and geological structures formed during each geological period from the Precambrian to the Cenozoic. Visit the 20 geosites recommended by the Mudeungsan National Geopark and enjoy the beautiful scenery along with the study of the geological era.

    Why don't you visit the 20 geological landmarks recommended by the Mudeungsan National Geolpark, and study with the beautiful scenery and even the geology era?

  • Geological value 02

    The type locality of the Mesozoic volcanic activity in the southwest part of the Korea peninsula!

    The volcanic activity on the peninsula of the Mesozoic era has been sporadic and wild, especially in the Mudeungsan area, where volcanic activity around the southwestern peninsula can be seen. There were at least three volcanic eruptions in the Mt. Mudeung area including Gwangju, Damyang and Hwasun.

  • Geological value 03

    The largest colonnade in the world!

    The colonnade in Mt. Mudeung distributed to at least 11㎢.

    In Gwangseokdae colonnade, the diameter of the columnar joint is up to 7m.

    The characteristics of Columnar joints in the Mudeungsan area

    Columnar joints in the Mudeungsan area graph
    Columnar Joints in the Mudeungsan area were formed in the late Cretaceous and show a wide range(over 3km2 scale) on the mountain more than 750m above sea level, which is the only one in the world.
    They have a great value and academic significance in that they shows the history as they were. The columnar joints developed at Mudeungsan Mountain are geologic structures developed by contraction due to slow cooling dacitic tuff composed of volcanic ash expelled in the volcanic explosions during the late Cretaceous period of the Mesozoic era (approximately 85~87 million years ago). This columnar jointed Mudeungsan Tuff was exposed to the ground surface by weathering after a long time to consequently create the colonnades.
    The Mudeungsan Tuff was formed by one or more than two eruptions, in which the columnar joints in Gyubong Colonnade are of world-class scale with the column width of up to 7m. The columnar joints in Mudeungsan Mountain are designated as Natural Monument No. 465.
  • Geological value 04

    Highest-density distribution of the block stream in South Korea

    • Deoksan block stream

      MG06 Deoksan block stream

      • The length of block stream is about 600m and the width is up to 250m.
      • About 130,000㎡ of blocks are clearly exposed making it the largest block stream in the Mudeungsan Area.
    • Jigong block stream

      MG07 Jigong block stream

      • Total area is 42,000㎢.
      • The block stream on the upper side is at an altitude of 1,000~1,100 m and 150 m wide.
  • Geological value 06

    Identified the diversity of dinosaurs and the theory of dinosaur acceleration in the Korean peninsula.

    • Seoyu-ri Dinosaur Fossil Site

      MG18 Seoyu-ri Dinosaur Fossil Site

      • The Seoyu-ri dinosaur fossil site is a geologically important place and has six sedimentary zones where about 1,500 dinosaur footprints and 73 trackways are observable.
      • Approximately 88% of these footprints belong to carnivorous deinonychosaurs. Small deinonychosaur footprints are especially abundant.
      • This site in Hwasun, unlike most other dinosaur footrpint fossil sites, has intensive footprint assemblies in small areas.
      • Based on these footprints, new research results have been reported including unusual tracks and acceleration theory of dinosaur movement (Kim and Huh, 2010).
    • World-class geological attractions blended culture and nature

      World-class geological attractions blended culture and nature

      • Seoyu-ri Dinosaur Fossil Site is on the Korean World Nature Heritage Tentative List (2007) as part of the Korean Cretaceous Dinosaur Coast.
      • Hwasun Dolmen Jangdong Tuff was inscribed as the UNESCO World Heritage in 2000 as part of the serial Gochang, Hwasun and Ganghwa Dolmen World Heritage property.
      • Unjusa Stratified Tuff is now on the Korean World Cultural Heritage Tentative List (2017) and finally we plan to apply as a World Heritage Cultural Heritage in 2018.
