Linking morphodynamics of deltaic distributary networks to stratigraphic connectivity of channel bodies

Elisabeth Steel - Queen’s University

11/08/2021 4:00 pm (London)

In deltaic environments, distributary channel networks serve as the primary conduits for water and sediment. Once these networks are buried and translated into the subsurface, the coarse-grained channel fills serve as likely conduits for subsurface fluids such as water, oil, or gas. This talk will focus on a new method for building synthetic stratigraphy from surface imagery and will discuss how the temporal evolution of a delta topset can be used to constrain subsurface architecture.

Submarine channel-lobe transition zones in an ancient passive-margin turbidite system

Lilian Navarro - Cape Breton University, University of Ottawa

18/08/2021 4:00 pm (London)

Deep-water turbidite systems have been the focus of much research during several decades, particularly much work has been done on slope channels and associated levees and basin-floor depositional lobes, but with much less attention devoted to the channel to lobe transition zone (also known as CLTZ) that separates them. Based on detailed lithological and architectural analyses of an interval consisting of intercalated, sheet-like, sandstone-rich strata that transition upward to channelized sandstones bounded by mudstone-rich strata of the Neoproterozoic, passive-margin Windermere turbidite system in the southern Canadian Cordillera, this study provide new insights into the spatial and temporal development of an ancient channel-lobe system and its related CLTZ (s), which are here interpreted to be largely linked to major changes in sediment supply and related flow characteristics (such as flow efficiency, and bypassing versus depositional character).

Disentangling the controls and orbital pacing of South-East Atlantic carbonate deposition since the Oligocene (30-0 Ma)

Anna Joy Drury - University College London

25/08/2021 4:00 pm (London)

In this study we use XRF core scanning to approximate carbonate content at Wallis Ridge in the Southeast Atlantic. We then look at how the patterns of carbonate deposition in this region have changed over the last 30 million years, and see what this record can tell us about how climate, the cryosphere and the carbon cycle interacted since the early Oligocene.
