The School of Geography, Earth and Environmental Sciences organises a regular series of research seminars throughout the academic year to which everyone is welcome to attend. Speakers - both external and internal to the University - will talk on topics related to all aspects of Earth Sciences.
Today's speaker is Grant Cole from the University of Plymouth.
Architectural analysis facilitates the identification of the individual building blocks (facies/elements) that make-up a depositional system or setting and can be applied at the field-wide/basin scale (large) through to the bedding scale (small). This approach combined with sequence stratigraphy (which identifies changes in the rates of sediment supply vs the rate of accommodation space creation) allows for the determination of the spatial and temporal changes/evolution of the depositional system and their controls. The results of which can then be used as an analogue against subsurface (seismic and well data), laboratory experiments (flume tests) and/or modern (Mississippi delta) examples.
The above approach has been applied to a superbly exposed succession of Lower Cretaceous, terrestrial to open marine siliciclastic and carbonate rocks, in the region of Aliaga (Teruel province), central-eastern Spain. The focus of the field-based study are the delta front sandstones of the Barremian-Lower Aptian Xert Formation. This presentation explores the large and small scale architecture of the study area and puts forward possible controls on their spatial and temporal evolution.
