“…Bernard et al (2012a) reported nanoporous pyrobitumen (e.g., post-oil solid bitumen) in a Posidonia Shale sample at 1.45% VRo, but no organic nanoporosity in samples at 0.5% and 0.85% VRo. Milliken et al (2012) demonstrated that secondary porosity develops primarily in intergranular organic matter (e.g., post-oil solid bitumen) instead of within particulate organic matter (e.g., kerogen) and that porosity increases with increasing total organic carbon content. Hao et al (2013Hao et al ( , p. 1342 concluded that "gas sorption in organic-rich shales is mainly associated with micropores" (<2 nm).…”

“…the amount of organic matter flux, the type of organic matter present, the detrital grain assemblage, the sediment accumulation rate) is therefore critical in determining the characteristics and variability within any fine-grained sedimentary succession (e.g. Macquaker et al 2007;Milliken et al 2012;Hart et al 2013;Milliken 2014;Lazar et al 2015a;Schieber 2016a). Previous work on mud depositional settings has principally focused on processes acting on shelf (e.g.…”

A paucity of studies on mud-rich basin slope successions has resulted in a significant gap in our sedimentological understanding in these settings. Here, macro-and micro-scale analysis of mudstone composition, texture and organic matter was undertaken on a continuous core through a mud-dominated slope succession from the Marl Hill area in the Carboniferous Bowland Basin. Six lithofacies, all dominated by turbidites and debrites, combine into three basin slope facies associations: sediment-starved slope, slope dominated by low-density turbidites and slope dominated by debrites. Variation in slope sedimentation was a function of relative sea-level change, with the sediment-starved slope occurring during maximum flooding of the contemporaneous shelf, and the transition towards a slope dominated by turbidites and then debrites occurring during normal or forced shoreline progradation towards the shelf margin. The sediment-starved slope succession is dominated by Type II kerogen, whereas the slope dominated by low-density turbidites is dominated by Type III kerogen. This study suggests that mud-dominated lower slope settings are largely active depositional sites, with consistent evidence for sediment traction. Additionally, the composition and texture of basin slope mudstones, as well as organic content, vary predictably as a function of shelf processes linked to relative sea-level change.

“…Scanning electron micrographs indicate the presence of laminar organic matter and also abundant silt-grade detrital quartz ( Figure 12D). Whilst it is difficult to differentiate detrital and diagenetic quartz without cathodoluminescence data (Milliken et al, 2012;Schieber, 2000), textural evidence suggests that some quartz grains may be recrystallized biogenic silica ( Figure 12E). Lower Holywell Shale samples from River Terrig contain 0.6 -3.4 wt % TOC (Table 1).…”
