Chris Jackson visited Jean-Marc Daniel and Fadi Nadar at IFP Energies Nouvelles in Paris (13th June) to discuss results arising from an ongoing collaborative project focused on the salt tectonics of offshore Lebanon. Petroleum Geoscience MSc student Ciprian Verdes is currently analysing the stratigraphy and structural style of Messinian salt, with a particular emphasis on intrasalt deformation.
Robin Thomas, a 4th year undergraduate student has joined the group to complete a UROP summer placement working on a collaborative project with Oliver Duffy and Rebecca Bell from the BRG and Adriana Paluszny from the Rock Mechanics Research Group. Robin aims to examine the growth and interaction of normal faults in multiphase rifts using 3D finite element numerical modelling.

The Basins Research Group (BRG) turned out mob-handed for the Geometry and Growth of Normal Faults conference, which was held at the Geological Society of London (23rd-25th June) in memory of Juan Watterson, the god-father of modern thinking on normal faulting. Thilo Wrona, Craig Magee and Chris Jackson gave oral presentations, and Antje Lenhart, Han Claringbould, George Fisher, Stephen Watkins, Olly Duffy, Lewis Ryan, David Reader and Tom Barling all presented posters. George, Stephen, Lewis, David and Tom deserve special mention as their posters arose from work completed as part of their MSci degrees. Well done all!
Rebecca Bell gave a talk entitled “Did the Earth move for you?” as part of the London events for the Pint of Science Festival 2014, held at the Hoop & Toy in South Kensington. The talk introduced members of the public to the recent discovery of slow slip seismic events at subduction zones, and even included a few interactive demonstrations!
Susie Maidment is currently undertaking three months of fieldwork in Colorado, Wyoming and Montana, where she is studying and palaeomag sampling the Upper Jurassic Morrison Formation, which is home to all of the best dinosaurs! (Stegosaurus, Allosaurus, Diplodocus...) Good luck Susie!
As part of his Visiting Scientist position, Chris Jackson spent two weeks at the Bureau of Economic Geology (BEG), University of Texas at Austin, working with members of the Applied Geodynamic Laboratory (AGL). Together they focused on the use of 3D seismic reflection data to image complex internal structures within salt diapirs. Ongoing work will use scaled physical models to investigate the controls on salt diapir growth and internal deformation.
Azli Abu Bakar also visited the Iron Mountain Core Store in Aberdeen and the BGS Core Store in Keyworth (26-30th May) as part of his study of the sedimentology of the Upper Jurassic deposits of the Central North Sea. His previous visits last year were focused on the marine deposits of the Fulmar and Pentland formations, while in this trip he focused on the deepwater(-ish?) deposits of the Heather and Kimmeridge Clay formations. His time there was graced by the presence of his eminent supervisors, Chris Jackson, who accompanied him for two days (which included a sleeper train trip of death from Aberdeen to Nottingham via Crewe and Derby), and Howard Johnson, who managed a quick trip to view the cores on the last day in Keyworth. A total of around 350 m of cores were logged and, overall, he has obtained more than 1.5 km of core data from 27 offshore wells in the CNS. Plenty to keep him busy for the rest of his study - good luck Azli!
Chris Jackson attended the ‘Brae Play’ conference, which was held at the Ardoe House Hotel, Aberdeen (23rd-24th April 2014). The conference focused on the structure, stratigraphy and hydrocarbon systems of the South Viking Graben and surrounding areas. He presented two talks; the first focused on the role that thin-skinned, gravity-driven faulting above salt played in controlling the dispersal of Upper Jurassic turbidite sands, and the resultant stratigraphic of late syn-rift reservoirs. The second talk investigated the kinematics of gravity-driven normal faulting, with particular emphasis on the factors that control sub-seismic slip rate variability.
Azli Abu Bakar, Abdulaziz Al Balushi, Dan Collins, Peter Fitch, Yvette Flood and Marijn van Cappelle all attended AAPG Annual Conference & Exhibition 2014 in Houston, Texas to present their work.
Great work all! See below the break for AAPG poster/presentation titles and abstracts!
Dan Collins, Oliver Duffy, Peter Fitch, Chris Jackson, Antje Lenhart, Matt Reeve and Marijn van Cappelle all acted as demonstrators/co-leaders during the MSc Petroleum Geoscience fieldtrip to Utah and Texas. The Utah leg of the trip was led by Gary Hampson.
Marijn van Cappelle is currently undertaking fieldwork on the Sego Sandstone in the Book Cliffs, Utah, USA. Howard Johnson, Peter Allison, Gary Hampson and Daniel Collins have joined him in the field for discussion, and Marijn is being assisted in the field by Julia Beckert (Imperial College Carbonate Research Group) and Menno Hofstra (University of Leeds). Marijn is investigating the facies architecture of the transition from channalized to unconfined flow at the delta front of tide-dominated deltaic systems.
Well done all!
Rebecca Bell gave a guest lecture at the Institute for Geophysics, University of Texas (UTIG) in Austin on “Next-generation seismic experiments: wide-angle, multi-azimuth, three-dimensional, full-waveform inversion”. Rebecca also gave a guest lecture on “Recovering physical property information from subduction plate boundaries using 3D full-waveform seismic inversion” at GNS Science in Wellington, New Zealand.
Dan Collins, Howard Johnson and Marijn van Cappelle all gave talks to the Clastic Reservoir Research Team at Shell, Houston. Dan's talk was entitled: ‘The Macrotidal Miocene: Ocean modelling and insights into sedimentary facies analysis in the Mio-Pliocene, NW Borneo, South China Sea’, Howard’s talk was entitled: ‘Nature, origin and evolution of a Late Pleistocene incised valley-fill, Sunda Shelf, Southeast Asia’ and Marijn’s talk was entitled: ‘Tidal- to fluvial transitions in deltaic deposits: An outcrop analogue from the Sego Sandstone (Book Cliffs, USA) compared with the sub-surface Ile Formation (Halten Terrace, Norway)’.
See below the break for abstracts.
Well done all!
The Basins Research Group (BRG) at Imperial College London focuses on the geodynamic, struc-tural, and stratigraphic evolution of sedimentary basins. This range of ac-tivities is centred around a multidisciplinary group of Earth Scientists who are committed to understand-ing the fundamental geo-logical processes opera-ting in evolving sediment-ary basins, and the application of this under-standing to determining the nature, origin and occurrence of natural resources (see Themes).
