Nearly 3000 continuous metres of Eureka Sound Formation sandstones, shales and coals were examined in outcrop along Kanguk Peninsula, Axel Heiberg Island, N.W.T., in the present study. From these rocks, diagenetic parameters such as illite crystrallinity, 1.0 nm peak sharpness ratios, proportion of...

Nearly 3000 continuous metres of Eureka Sound Formation sandstones, shales and coals were examined in outcrop along Kanguk Peninsula, Axel Heiberg Island, N.W.T., in the present study. From these rocks, diagenetic parameters such as illite crystrallinity, 1.0 nm peak sharpness ratios, proportion of illite in illite/smectite mixed layers, and sandstone cement paragenesis have been used in combination with thermal modelling to make inferences about the thermochemical evolution of the strata and their contained pore waters. The findings from both the thermal modelling and sandstone petrology suggest that a syn- or post-tectonic heat flow anomaly existed whereby heated Na⁺-enriched waters passed from diapir cores (where halite dissolution occurred) into laterally adjacent permeable lithologies such as coals and arenites.
