“…Basin-wide forcing implies a more significant probability of the occurrence of sandstones within these stratigraphic intervals in the otherwise overall low net-to-gross Westoe and Cleaver Formations. Similar variations in net-to-gross ratios associated with long-eccentricity climate control are suggested for the Upper Carboniferous Upper Silesian (Opluštil et al, 2022) and Appalachian Basins (Le Cotonnec et al, 2020).…”

“…Palaeo-polar ice volume changes are also related to palaeo-tropical climatic variations with changes in rainfall and vegetation affecting upstream sediment supply and leading to cyclic behaviour in fluvial systems (e.g. Noorbergen et al, 2018; Opluštil et al, 2022). There is strong evidence that Pennsylvanian glacial-interglacial fluctuations produced significant climatic variations, with shifts from perhumid to semi-arid seasonal climates recorded in palaeotropical Euramerica (Cecil et al, 2003; Roscher and Schneider, 2006; DiMichele et al, 2010; Eros et al, 2012).…”

“…Davydov et al, 2010;van der Belt et al, 2015). Besides base-level changes, upstream sediment fluxes, and variations in mid-stream water and vegetation levels have also been proposed as mechanisms for cyclothem formation (Jirásek et al, 2018;Opluštil et al, 2019Opluštil et al, , 2022. Smith and Joeckel (2020) demonstrated the potential for improved reservoir characterisation with a stratigraphic framework based on cyclothem correlations.…”

Orbital driven climate control on sedimentation produces regional, stratigraphically repetitive characters and so cyclostratigraphic correlation can improve correlation and identify stratigraphic trends in borehole sections. This concept is commonly used to correlate marine and lacustrine strata. However, in the alluvial domain, its use is more challenging because internal, local dynamics controlling sedimentation may interfere with the expression of cyclic climate forcing. Intervals of low net-to-gross may be important for successful application in this domain as they tend to better document regional changes. This study applies climate-based stratigraphic correlation concepts to improve well correlations, characterise vertical sand distribution, and identify potential reservoir targets in a generally low net-to-gross interval. Coarsening upward sedimentary repetitions (cyclothems) are identified and correlated with high certainty in nineteen well sections in the upper Carboniferous Westoe and Cleaver formations of the Silverpit Basin. Local sedimentary dynamics provide variability in the character of the cyclothems and several types of cyclothem are classified. Correlation of sections using cyclothems recognised on wireline logs is done twice: once manually and once semi-automatically. The semi-automated correlation is based on calculation of deviation curves which depict stratigraphic changes that are less dependent on absolute wireline values and follow vertical trends more clearly. The correlations provide composite stratigraphies that are analysed using vertical proportions curves. Both approaches yield similar results in terms of stratigraphic trends. However, for detailed correlation of wells, the manual correlation is better at accounting for any local variability within the system. The same two zones of higher net-to-gross ratios are found using both correlation methods. These are linked to palaeoclimatic changes driven by long eccentricity and the proposed climate stratigraphic model has predictive value for identifying sandstone occurrence. The climate-based stratigraphic correlation improves the assessment reservoir distribution and properties on small (10–20 m thickness) and large (100–200 m thickness) stratigraphical scales.

“…As a working assumption, the variation of sideritic contents, distribution of shapes and forms, and precipitation complexity is facies-related, likely correlative with the characteristics of a paralic Coalfield (Opluštil et al 2022, Shishlov 2009, p. 8, Hacquebard 1998). Bell (1938, p. 9) regarded the Sydney Coalfield as a freshwater deposit [sic limnic], pointing out "… the quiet tectonic develop-ment…".…”

Reported are descriptions of twelve samples representing a variety of sideritic structures, including nodules mostly from roof shale of the Middle Pennsylvanian Sydney Coalfield, Canada. The co-occurrence of fossiliferous nodules and compression fossils in the shaley roof rocks at Point Aconi enhance greatly palaeontological information. Newly discovered in a coal seam, and part of the sample, is a 40 mm thick continuous sheet-like layer of siderite with abundant permineralized-like-compressed small to micron-sized structures in a rather evenly-sized sideritic matrix, probably indicating a genetic origin different from that of the nodules. Methods include some thin-section, and two X-Ray analysis. However, large systematic sampling is a prerequisite to explore that situation, which additionally could provide faunal information for Euromerican correlation.
