Widespread hydrocarbon occurrences are
present in Devonian-Carboniferous carbonate units of the
The sedimentary facies of
Devonian-Carboniferous strata reflect deposition on the margin of Baltica: on
the Barents Sea side of the archipelago, shallow marine shelf carbonates were
deposited, with abundant coral-stromatoporoid reefs; on the Kara Sea side of
the archipelago, deep-water slope and basin floor settings predominate, with
trubidities, shales, cherts and carbonate mudstones. A number of potential
source rocks were identified in the succession. Extensional tectonism affected
deposition, particularly during the late Givetian to early Frasnian interval
when fault-block rotation, subaerial erosion and basic volcanism occurred.
