The Department of Geology and Mines (DGM) was established in April 1981 after the 43rd resolution of Lhengye Zhungtshog. Prior to the establishment of the DGM in April 1981, most of the geologic mapping and mineral exploration activities in the country were undertaken by the Geological Survey of India (GSI) who continued their work concomitantly with the DGM until their exit in 2002. Today, the Deparment of Geology and Mines has four divisions, each division supported by different sections:
- Geological Survey of Bhutan (GSB) Division
- Glaciology Division
- Seismology Division
- Mining Division
The functions of the each division are mentioned as here under:
