“…Only coal is targeted, because peatlands are considered to represent more continuous and in situ records of accumulation compared to terrestrial clastic-dominated sedimentary successions (Davies et al, 2006;Wadsworth et al, 2010), and the surface that separates the bases of some coals and their underlying sediment have been interpreted as hiatal (e.g., Aitken and Flint, 1996;Jerrett et al, 2011b) and likely to have been subject to postdepositional subaerial exposure, truncation, and diagenetic alteration (Gardner et al, 1988;Aitken and Flint, 1996;Driese and Ober, 2005) and postcompaction penetration by the roots of significantly later plants. The purpose of this study is to demonstrate that a regional record of paleoatmospheric d 13 C can be extracted from the terrestrial sedimentary record and to compare the record of terrestrial d 13 C with that from extensively described time-equivalent marine sections.…”

Petrological and δ 13 C analyses were under taken on contiguous specimens of coal and intercalated minor organicrich clastic sedi ments collected from coal seams spanning the CretaceousPaleogene boundary in the Alberta and Saskatchewan portions of the Western Interior Basin. The generally high smectite content of the coal suggests that the original mires were largely small, discon nected, and rheotrophic, readily receiving abundant waterborne detrital clastic mate rial of largely volcanic origin. Nevertheless, using the distinctive claystone that marks the CretaceousPaleogene boundary as a regional datum , it is possible to correlate cycles in the vitrinite and inertinite compo sition of the coals over >500 km. Estimates of peat accumulation rates suggest that the cycles in vitrinite and inertinite composi tion represent regional, cyclic fluctuations in wildfire and oxi da tion of the peatlands and overlying canopy at a frequency of hundreds to thousands of years. The likely causes of these fluctuations were cyclic, regionalscale changes in temperature. The Cretaceous Paleogene boundary event occurred early during a phase of gradually increasing tem perature and/or decreasing rainfall, but peak wildfire and desiccation of peat occurred up to 14,000 yr later than the Cretaceous Paleogene boundary, and the mires did not experience significant water stress in the im mediate aftermath of the extinction event. A persistent, 1.5‰-3.0‰ negative δ 13 C excur sion occurs across the CretaceousPaleogene boundary, but it cannot be readily separated from four, further negative excursions later in the earliest Danian. The negative carbon isotope excursion linked to the Cretaceous Paleogene boundary began a few hundred years before the event itself, and recovery occurred within 21 k.y., and possibly in as little as just a few thousand years, consistent with recently calibrated shallowmarine δ 13 C records. Hence, the atmospheric and surface ocean carbon pools were coupled at this time. The absence of evidence for catastrophic change in the climatic regime at the time of the CretaceousPaleogene extinction in these mires supports the notion that the negative shift in atmospheric δ 13 C was brought about by changes in the δ 13 C composition of the sur face ocean. This is consistent with the greater magnitude of extinction experienced by ma rine fauna relative to the terrestrial realm.

“…Within the Hailar Basin, coal seams have a relatively shallow burial depth (mostly < 1000 m), low coal rank (Ro, max < 0.5%), and anomalous thickness (up to 40 m) (Guo et al, 2018). The coal seams preserve continuous and in-situ records of peat accumulation (Wadsworth et al, 2010). Almost all inertinite (Fusinite, semifusinite and inertodetrinite) is believed to be the products of incomplete combustion as a result of wildfire (Scott, 2002;Glasspool and Scott, 2010).…”

“…This stratigraphic framework acknowledges but does not focus on other factors (e.g., climate, groundwater, vegetation, and geomorphology) that influence peat accumulation. By applying this stratigraphic framework, coal is integrated into stratigraphic models (Davies et al., 2005; Jerrett, Flint, et al., 2011; Michaelsen et al., 2000; Staub, 2002) where it forms an interpretative bridge between the marine and terrestrial realms (Wadsworth et al., 2010).…”

• To understand how peat enters long term carbon storage requires consideration of peat accumulation over periods of 10 5 to 10 6 years. • Peat accumulation over these timeframes requires sustained storage of water above depositional base level • This has profound implications for our understanding of peat in the earth system and the interpretation of the geological record Accepted Article This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record.
