Cretaceous coal-bearing sequences from the Moose River basin in northern Ontario and the Peace River basin in northeast British Columbia were analysed for trace- and major-element contents. Modes of occurrence of the trace elements are proposed on the basis of Pearson correlation coefficients and scanning electron microscopy coupled with energy-dispersive X-ray analysis.The Moose River basin lignite was deposited in an alluvial floodplain environment, and the restricted mineralogy, dominated by quartz and kaolinite, reflects derivation from a highly weathered terrain. The bituminous coal from the Peace River basin was deposited in an alluvial to deltaic environment, with a dominant mineralogy including quartz, illite, kaolinite, mixed-layer clays, carbonates, barite, feldspar, and pyrite.Trace-element contents in both deposits are comparable to the average concentration in United States coals. Modes of occurrence of trace elements in the coals are extremely variable and depend on local conditions both during deposition and subsequently. Association with the organic matter is the most common mode of occurrence of trace elements in the Moose River basin lignites, whereas clay minerals are important trace-element sites in the Peace River basin coal.Factors including coal rank, clay mineralogy, nature of the surrounding rocks, and composition of the groundwaters appear to have important influences on the concentrations of the trace elements and their siting in the coals.

The Long Rapids Formation, a sequence of interbedded black shales, green–grey mudstones, and carbonates in the Moose River Basin of northern Ontario, is Late Devonian in age and has counterpart equivalents in the Michigan, Appalachian, and Illinois basins. The Long Rapids Formation has a maximum known thickness of 85 m and can be divided into three informal members. Based on conodont studies, the formation spans the Frasnian–Famennian age boundary.The Long Rapids Formation is an organic-rich, laminated, marine black-shale sequence interbedded with green–grey mudstones and concretionary carbonate interbeds and nodules. The environment of deposition was principally reducing, allowing for preservation of large amounts of organic matter both originating in the overlying water column and derived from terrestrial sources. The depositional basin was stratified, and anoxic bottom waters and oxic surface waters were separated by a pycnocline. The position of the pycnocline (or the absence of it) dictated the type of sediment facies deposited.The Moose River Basin in the Late Devonian was located on the Laurasian Continent, proximal to the equator, in an area where tropical weather conditions prevailed. Conditions were warm and wet along the Appalachian highlands, and farther inland they were warm and dry as a result of the rain-shadow effect. The black shales in the Long Rapids Formation represent a period of transgression of the large epicontinental Catskill Sea, and the green–grey mudstones and carbonates represent periods of minor eustatic or tectonic perturbations.Dark-coloured, organic-rich shale facies (sometimes with abundant bioturbation) are succeeded by lighter coloured shale or mudstone facies and carbonate facies in a repetitive fashion. The facies sequences appear to represent a three-part sedimentary package, or "rhythm", that is very common in the lower two members of the Long Rapids Formation. Bioturbation and total organic carbon content are less in the green–grey shales or mudstones, as well as in the carbonate facies, than in the darker shale facies.

Abstract Peatland waters of the Moose River basin, as well as surficial sediments and vascular plants of the estuary were sampled in 1982. Elevated levels of PCBs were found at all five peatland sites; concentrations ranged from 28 to 65 ng/L. Of the seventeen organochlorine pesticides investigated, the hexachlorocyclohexane isomers (a-and y-BHC) were the most prominent with total BHC concentrations ranging from 1.5 to 13.7 ng/L. The presence of these contaminants in ombrotrophic bogs indicated that there was atmospheric deposition of organochlorine contaminants in the basin. Analyses of surficial sediments, collected from tidal flats and coastal marshes, showed that PCBs and organochlorine pesticides were not present. Samples of Triglochin maritima L. seed heads and Typha latifolia L. roots were also free of PCBs.

Moose River

The Moose River Basin in Ontario, Canada, contains nearly 1 km of Silurian marine strata, and although it has been studied for more than a century, its precise correlation globally has not been constrained. Herein, a core from the Victor Mine in the Moose River Basin was examined for conodont biostratigraphy and carbonate carbon (δ13Ccarb) isotope chemostratigraphy to provide a detailed chronostratigraphic framework for the Silurian strata (Severn River, Ekwan River, and Attawapiskat formations) in the Moose River Basin. The recovery of Aspelundia expansa, Aspelundia fluegeli fluegeli, Distomodus staurognathoides, Ozarkodina polinclinata estonica, Pterospathodus eopennatus, and Aulacognathus bullatus, as well as the lower Aeronian, upper Aeronian, lower Telychian (Valgu), and ascending limb of the Sheinwoodian (Ireviken) positive carbonate carbon (δ13Ccarb) isotope excursions provide significantly improved chronostratigraphic correlation of Llandovery strata in the Moose River Basin.
