The paper presents results of the study on oil shale mining (Estonia underground mine) possibilities under the Selisoo mire. The Selisoo area is 2,051 ha in extent, and most of the mire is in natural state. Peat layer consists of thick (4.4–6.5 m)

The Dividalen Group is exposed in a narrow zone along the eastern Caledonian front of northern Fennoscandia. Trace fossils provide important age constraints in these largely siliciclastic strata and demonstrate that in Sweden the entire Dividalen Gro

The 150-300 m thick Ediacaran-Devonian sedimentary cover of Estonia, which contains the commercial oil shale deposit, is divided into blocks by linear fracture and tectonic disturbance zones. Along these zones the bedrock is modified, its composition

Three linear tectonic dislocation groups of different orientation (and probably also of different age) cut the Estonian oil shale-kukersite deposits. Two younger groups of structures are typical fault zones with N-NE and NW trends, which are expresse
