PROSPECTS OF LITHUANIAN SILURIAN SHALE GAS, BALTIC SEDIMENTARY BASIN; pp. 357–372 [PDF]

Oil Shale, 2016
The Baltic sedimentary basin contains numerous hydrocarbon fields in Lithuania. The Lower Silurian shales are considered as potential for shale gas exploration. The thickness of shale units within the oil window ranges from 115 to 180 m in west Lithuania.

Weathering of phosphorus in black shales [PDF]

Global Biogeochemical Cycles, 2002
Rock weathering is the ultimate source of phosphorus (P) to the oceans, where P can be a limiting nutrient for biological production. In this paper, P weathering is examined in soil chronosequences formed in weathering profiles on the organic‐rich Woodford Shale, New Albany Shale and Green River Shale.

Hydrocarbon generation potential and organic matter accumulation patterns in organic-rich shale during the mesoproterozoic oxygenation event: evidence from the Xiamaling formation shale

Geomechanics and Geophysics for Geo-Energy and Geo-Resources, 2023
A significant deposition of black shales occurred during the Mesoproterozoic Oxygenation Event (MOE). In order to investigate the hydrocarbon generation potential and organic matter enrichment mechanism of these shale deposits, we studied the Xiamaling ...
