The starting material, kukersite
, is known to contain up to 3% sulphur, whereas about 3.3% of the mineral matter is pyrite .
In the latter region, unusual environments with kukersite
kerogenrich deposits contributed to the development of a highly diverse biota.

kerogen evaluated by C-13 MAS NMR spectra," Fuel, vol.
The total amount of water-soluble phenols from high unit capacity generators for shale oil production from kukersite
(Kiviter process) is over 5.5 kg per tonne of processed shale; for 5-methyl resorcinol it is more than 1.5 kg and for 2,5-dimethyl resorcinol more than 0.4 kg per tonne .
oil shale forms horizontal sequences in the limestone from which it has been extracted in underground mines.
The Viivikonna Formation of the Kukruse Regional Stage is the main stratigraphic unit containing oil shale (kukersite
) in the Ordovician strata of Estonia (Fig.
Comparison and parallels with fossil BM using data obtained for kukersite
oil shale have been drawn further here and there.
oil shale is the major fuel used for power generation in Estonia.
Interaction of Estonian kukersite
with organic solvents: a volumetric swelling and molecular simulation study.
Ash utilization after combustion and thermal processing of Estonian (kukersite
) oil shale.
On the kukersite
layers in the Johvi and Keila Regional Stages in Estonia.
For example, in a recent summary for Estonian kukersite
oil shale derived oils, it has been shown that the publicly available information is spotty and poorly suitable for evaluating the applicability of available thermodynamic property prediction methods, even for the simplest approaches based on "undefined" pseudocomponents .
