Formation of Mudeungsan Area

Records of the Breath of the Earth

Since the birth of the Earth, the Mudeungsan region has been recording about 2 billion years.

The solid foundation made during thepre-Cambrian era was strengthened by heat and pressure, and covered with lime and sandbags during the time of thegonigen, which was briefly submerged in the warm, shallow sea. Later in the middle ages, sedimentation basins opened, and violent volcanic activities that shook the entire Korean Peninsula surprised the dinosaurs, and the fierce rain, wind and cold that were in the Neolithic Age carved the pieces of time and brought them to their present form.

As such, the Mudeungsan region has recorded the breath of the earth from the pre-Cambrian period to the present, leaving us valuable evidence that it is a geological heritage.

STAGE 01 Precambrian Era

  • Hydrostatic rock is the rock at the bottom of the Mudeungsan area.
  • The rock has been made about two billion years ago, and has been strengthened by heat and pressure, and supports the area of Mount Mudeung.

STAGE 02 Paleozoic

  • The Mudeungsan Mountain region was warm and shallow in the early days of the alpine era, when carbonate formations (limestone) from the sea were deposited at the bottom.
  • By the late days of the Prehistoric Age, a long basin was formed in the north-western andsouth-western directions, and sand and other sediments were piled up.

STAGE 03 Mesozoic - Jurassic

  • ① In the central part of the Korean Peninsula, a large-scale granite movement took place in the northeast-southwest direction. The granite was created by slowly cooling and solidifying the underground core. The one made at this time is Gwangju granite.
  • ② Since then, the granite in the heart has been in full bloom, and erosion and oppression have continued to occur until now, and the indicators have revealed it, allowing us to see the granite in Gwangju around us today.

STAGE 04 Mesozoic - Cretaceous

  • ①In the central part of the Korean Peninsula, a huge perceptual movement took place in the northeast-southwest direction, and several small areas, including Neungju Basin, were created along the insulation.
  • ②Neungju Basin is the largest Cretaceous sedimentary basin in Jeollanam-do, which is located in Hwasun, Damyang, Gokseong, and Boseong, and dinosaurs roamed around large lakes (now Hwasun) in Neungju Basin, leaving traces in the sedimentary layers.

STAGE 05 Mesozoic - Cretaceous

  • The volcanic activity of Ansan rock has begun extensively in the northeast-southwest direction around Mudeungsan Mountain area.

STAGE 06 Mesozoic - Cretaceous

  • Volcanic activity began in Mudeungsan Mountain area, and several times, magma and ash erupted in large quantities to form a thick layer of lava. And a massive eruption caused an elliptical dent.
  • A few kilometers southwest of the magma venting center has begun to engage in a volcanic activity called glaucoma. The metamorphic lava flows or penetrates in large quantities in the form of a dome.

STAGE 07 Mesozoic - Cretaceous

  • Magma, which remained inside the basement, was introduced along the thermo-tropical zone formed around the macromolecular body, and the rock formed by entering the rock formations.

STAGE 08 the fourth stage of the Cenozoic Era

  • In the Cenozoic Era, rust and weathering took place, and rocks with columnar joints began to emerge.
  • During the fourth phase of the Cenozoic Era, many columnar joints were frozen, recorded repeatedly, broken and fell, forming the current rock monster.
  • In the Mudeungsan area, weathering continued, and soil was formed.
