Abstract
Tide-influenced Channel Deposits in the Lower Cretaceous Glauconitic Member, Southern Alberta
Abstract
In the subsurface of southern Alberta, the Glauconitic sandstone member of the lower Cretaceous Mannville Group contains channel-fill sandstone deposits interpreted to have formed in an estuarine environment under the influence of tides. The channel sandstones display physical sedimentary structures (bundles, mud-layer couplets) which are characteristic of Holocene estuarine tidal deposits. The channel sandstones are in gradational relationship with bioturbated interstratified sandstone-mudstone lithofacies which are thought to represent lateral accretion bedding associated with subtidal estuarine channel point-bar deposits.
