'Linking cyclicity from terrestrial to marine sedimentary successions'
NERC DTP
Supervisors: Dr Rob Duller and Dr Silvio De Angelis
Description: My research will focus on a fundamental aspect of stratigraphy: the presence of hierarchical organization and cyclicity at the full range of physical scales. Hierarchical cyclicity of this kind can be generated by autogenic process and allogenic processes. However, there is considerable ambiguity over what process dominates the stratigraphic record and under what conditions these processes dominate. The goal of my studentship is to elucidate the nature of clastic stratigraphic record, from the land-system to the marine-system with a focus on fan systems. To do this, laboratory experiments and numerical experiments will be used to test a theoretical framework, which will then be applied to a field-scale sedimentary succession. - Email Stephan

'Developing a new stratigraphic forward model to understand and predict carbonate platform geometries and facies distribution in syn-rift settings'
My project belongs to PD3 (Prediction of Deposition, Deformation and Diagenesis in Carbonate Systems), an industry-funded consortium involving academic staff and PhD students in the Universities of Bergen, Bristol, Manchester and Liverpool.
Supervisors: Prof. Peter Burgess
Description: My research focuses on the development of a numerical 3D stratigraphic forward model of carbonate strata deposited in syn-rift settings. The project started with an existing model, CarboCAT, and is refining existing and developing new algorithms to allow better modelling of the development of carbonate platforms in syn-rift settings. Analysis of the model output for a wide range of input parameters will improve our understand of how syn-rift settings generate various carbonate platform geometries, including carbonate strata shed off the platform tops into deeper water. Generation of 2D and 3D synthetic seismic images from CarboCAT model output will allow prediction of the likely seismic response of carbonate stratal architectures and reservoir heterogeneities formed in syn-rift settings. The final outcome of my project will be modelling tools and a database of results to assist seismic interpretation and carbonate facies prediction in complex extensional environments. - Email Isabella
