Drill Core Database

Please note! The Parliament of Estonia has made a decision that as of 01.01.2025, the Estonian Geological Survey will take over all tasks related to the geology field previously carried out by the Land Board.

Drill holes provide important information about the subsoil plots. Drill core database contains data used for compiling the Geological Base Map of Estonia, including descriptions and photos of the state-owned drill cores (~ 25000 boxes) and samples taken from them.

The most recent data can be found by searching the drill core database.
