| Zusammenfassung |
| The Bowland Shale (late Mississippian, early Carboniferous) has potential for the
unconventional extraction of hydrocarbons in the UK and in equivalent successions that
extend across Europe to the Lublin Basin, Poland. The Bowland Shale was deposited in a
marine epicontinental seaway and in a basinal setting. This study seeks to characterise the
controls (sedimentological, geochemical, biological, preservation) on the spatial and temporal
distribution of organic matter in the Bowland Shale within the Craven Basin (UK) and link
this to resource potential. This approach can also contribute to understanding the role that
these basins had as a sink for organic carbon (hence sequestered CO2) on the geological
timescale.
The preliminary data presented delineate variation in lithology (utilising sedimentary
logging, optical and scanning electron microscopy) and organic carbon content (including
TOC and stable isotope analysis) through an exposed succession of the Bowland Shale,
located in the Craven Basin, Lancashire. These analyses are compared with time-equivalent
borehole core sample(s) also located within the Craven Basin. The study will seek to quantify
the effect of modern weathering, by comparing between outcrop and borehole samples.
Where modern weathering is considered to be minimal, such analyses can be utilised as an
analogue used during exploration for, and classification of, prospective hydrocarbon intervals
for unconventional extraction. Future analyses will target approximately time-equivalent
sections across the Craven Basin in order to delineate the variation in type, abundance
and spatial distribution of organic matter in more proximal and/or distal locations. |
