The Revised Edition of the Korean Geological Map Released After 24 Years

[Asia Economy Reporter Junho Hwang] The revised edition of the "Geological Map of Korea," an encyclopedia of our land, has been published for the first time in 24 years.

The Korea Institute of Geoscience and Mineral Resources (KIGAM) published the revised edition (2019) of the 1:1,000,000 scale Geological Map of Korea on the 22nd. A geological map is a drawing that represents the distribution of rocks exposed on the earth's surface, geological structures, and stratigraphic conditions using colors, symbols, shapes, and lines on a topographic map. This map is used in various fields such as national land development, environment, and resources. Recently, it has also been utilized as fundamental data for national key industries, including transportation facilities, electricity and telecommunications, and nuclear power plant site selection.

KIGAM is the only institution in Korea that produces geological maps. In 1956, it created the first 1:1,000,000 scale geological map covering the entire territory of the Republic of Korea, known as the Daehan Geological Map (Registered Cultural Property No. 604). Following editions were released in 1981, 1995, and this year marks the fourth edition.

This edition of the geological map includes new information on strata and rocks classified using the latest geochemical analysis and dating techniques, and it reflects the reclassification of stratigraphy in the North Korean region. An English version and an explanatory booklet were also included to enhance usability.

Dr. Wonseo Ki, the lead researcher, stated, "The geological map reveals where past strata were formed and the processes of their changes," adding, "It will contribute not only to the geology of the Korean Peninsula but also to the study of the tectonic evolution of Northeast Asia."

Meanwhile, KIGAM has been producing 1:50,000 scale geological maps by dividing the entire country into 359 sections since 1924. As of this year, 95% of the total domestic area has been published, and completion is expected by 2025.
