Dating faults, fractures and fluids with U-Pb calcite geochronology:
appraising the relationship between deformation and basinal fluid-flow in the Cleveland Basin
Jack Lee, Durham University
The Cleveland Basin has long held a special place in the hearts of Yorkshire geologists with a rich geological history. Using cutting edge U-Pb dating techniques combined with structural analysis and isotopic traces we are re-evaluating the deformation and fluid-flow history in the Early Jurassic mudrocks. This furthers our understanding of the relationship between fluid-flow and deformation in mud-rich lithologies with important implications for mudrock seal integrity in petroleum systems and Carbon Capture and Storage.
Jack Lee is in the final year of a PhD at Durham University studying “Fracturing and fluid-flow in an exhumed Jurassic basin: an integrated field, microstructural, geochronological and isotopic study of vein mineralisation within mudstone-dominated successions”, supervised by Nick Roberts, Jonathan Imber, Bob Holdsworth, Andy Aplin, Richard Haslam and Cedric John. Jack had previously completed a MSc by Research at Durham University on “The Jurassic Source Rock Potential of the Celtic Sea and Western Approaches ” and also has three and a half years’ experience analysing abnormal fluid pressure in shales working for Ikon Science.
Jack was awarded a grant from the YGS Research Fund in 2018/19.
