The Sample Repository systematically stores rock/surface core samples and Quaternary marine sediment samples collected from mineral resources exploration (metal, non-metal, construction material,placer deposit), energy resources exploration (oil, hot spring, geothermal), nuclear power plant and waste disposal site survey, and applied geological survey (land subsidence) executed by the Korea Institute of Geoscience and Mineral Resources, and perform its duty as a geological sample library.
The Sample Repository systematically stores rock/surface core samples and Quaternary marine sediment samples collected from mineral resources exploration (metal, non-metal, coalfield, construction material,placer deposit), energy resources exploration (oil, hot spring, geothermal), nuclear power plant and waste disposal site survey, and applied geological survey (land subsidence) executed by the Korea Institute of Geoscience and Mineral Resources, and perform its duty as a "geological sample library".
Drill cores, rocks, mineral samples stored in the Sample Repository are 231,392.3 m rock drill core samples of 16,494 boxes from 2,964 sites acquired by the Korea Institute of Geoscience and Mineral Resources from 1973 to 2013 (excluding oil drill exploration), and 2,735 boxes of rocks and mineral samples.
In addition, Special Exhibition Hall was arranged in the Sample Repository, and is utilized as a space for relaxation through visits to the Special Exhibitions on diverse topics.
Metal drill cores
Starting with the copper deposit drill exploration in the Yeongyang area of Gyeongsangbuk-do in 1973, drill cores focused on rare-earth mineral deposit in the Hongcheon area of Gangwon-do in 2013, a total of 4,100 boxes are stored.
Non-metal drill cores
Focusing on non-metal mineral deposits, starting from the drill exploration of pyrophylite deposit in the Gasado area of Haenam-gun, Jeollanam-do in 1973, to zeolite deposit drill cores in the Guryongpo area of Pohang, Gyeongsangbuk-do collected until 1983, a total of 156 boxes are stored.
Coal drill cores
Mungyeong Coalfield area of Gyeongsangbuk-do in 1975, and drill cores of Boeun Coalfield area of Chungcheongbuk-do until 1991, a total of 463 boxes are stored.
Construction material drill cores
Starting from the Beomseong Mine of Pocheon area, Gyeonggi-do in 1986, to granites from the Samgwang Mine of Hadong area, Gyeongsangnam-do until 2000, a total of 1,526 boxes of drill cores are stored.
Groundwater drill cores
Focusing on groundwater development, from 1981 to 2001, there is a total of 2,253 boxes of drill cores collected from the Yeonggwang area.
Oil drill cores
The Pohang area of Gyeongsangbuk-do in 1975, Namgi of Gyeongsangnam-do and Haenam of Jeollanam-do between 1978 and 2013, and parts of drill cores done by Heungguk Oil, Inc. on Euseong Basin of Gyeongsangbuk-do in 1980, a total of 1,342 boxes are stored.
Other drill cores
Drill cores from North Korea, land subsidence survey drill cores, and parts of unconfirmed drill cores are stored.
