Geology and Geophysics team

Our ambition

Is to understand the geological structure and tectonic evolution of the Antarctic continent to generate new knowledge about its key role in the evolution of the Earth System itself. Our aim is to use state of the art technologies to explore both the landscape and the deeper structure of Earth hidden beneath the thick ice sheets that cover more than 99% of Antarctica. By achieving this we will produce new geological and geophysical maps and improve models and simulations of key geological processes such as mountain building, basin formation, magmatism and crustal growth.

We work collaboratively with national and international partners to deploy a combination of airborne and marine geophysics, spectral remote sensing, field mapping and geochemistry and geochronology to improve our understanding of the geological evolution of Antarctica and its super-continental linkages. Combining this with results from global geological studies we can interpret the role of Antarctica in the breakup of the Gondwana supercontinent as well as the assembly of earlier supercontinents, such as Rodinia and Columbia. Understanding Antarctic geology is also critical for comprehending the internal factors affecting ice flow dynamics and long-term ice sheet stability, in addition to climate and ocean processes. Our research provides unprecedented insights into the structure and evolution of interior East Antarctica and on the fundamental tectonic boundary between East and West Antarctica.

Team priorities

Science

Geology

  • Geochemical evolution of the Antarctic Peninsula magmatic system. Investigate the Earth’s crustal growth processes through studies of the Antarctic Peninsula as the southern continuation of the Andean Pacific margin
  • Geological and geophysical mapping of British Antarctic Territory. Develop a critical base-line for understanding and investigating Antarctica

Geophysics

  • Unveiling the South Pole Frontier. Assemble a new multinational and multidisciplinary team to explore one of last frontiers on Earth – the South Pole region south of 83⁰S to provide unprecedented insights into the structure and evolution of interior East Antarctica and the fundamental tectonic boundary between East and West Antarctica. The new gravity, magnetic, radar and ice surface datasets we will collect over the South Pole Frontier are urgently needed for global satellite gravity field determination, satellite magnetic studies and satellite altimetry missions
  • Revealing the mosaic of East Antarctica. To understand the different geological provinces, and some of the oldest rocks on the planet that are covered by the vast East Antarctic Ice sheet covers. Once thought to be a more or less homogeneous block, ground breaking geophysical exploration is revealing that the interior of East Antarctica is instead a complex mosaic of different geological provinces. Unique opportunities to comprehend the linkages between East Antarctica and ancient (Precambrian) supercontinents like Rodinia and Columbia are beginning to emerge. Comprehending how subglacial geology and geothermal heat flux may affect the largest ice sheet remaining on Earth is also a key priority.
  • Evolution of the West Antarctic and Weddell Sea Rift systems. To investigate and create new knowledge about the evolution of crustal and mantle processes that heralded the break-up of Gondwana. The West Antarctic Rift System is one of the largest and yet least understood continental rift systems on the planet. It is particularly critical as it forms the lithospheric cradle for several rapidly changing and potentially more unstable sectors of the West Antarctic Ice Sheet. The Weddell Sea Rift System underlies the Ronne and Fichner Ice shelves that buttress both the West and East Antarctic ice sheets.

 Technology, innovation and training

  • Airborne gravity, magnetic and radar provide the key tools we use for geophysical exploration of the ice covered Antarctic interior
  • Provide the broader geosciences community with critical new gravity, magnetic, radar and ice surface datasets over the South Pole region that are urgently required for global satellite gravity (GOCE) field determination, satellite magnetic studies (SWARM) and satellite altimetry missions (Cryosat-2)
  • State of the art geochemical analysis and dating is coupled with field based geological exploration and mapping to provide the most complete geological picture to date
  • Using and developing spectral remote sensing methods to map lithology and the target detection of minerals
  • Continued commitment to post graduate training through NERC Doctoral Training Partnerships and direct collaboration

Influencing and leading international programmes

  • Ongoing track record of successful exploration of remote and hostile frontier regions through major international collaborations such as the AGAP project over the Gamburtsev Subglacial Mountains
  • Play a key role in international projects compiling gravity (Ant-GP), magnetic (ADMAP2), and topographic (BEDMAP2) geophysical data for public release
  • Developing an international programme (with Greenland Geological Survey) to identify critical metals using spectral remote sensing

Stakeholder & public engagement

  • Producing new geological maps of British Antarctic Territory is part of our commitment to one of our key stakeholders, the FCO
  • Provision of geological and geophysical data sets to the wider scientific community
  • Publicising and explaining our scientific advances through the BAS Communications Team
  • Enthusing next generation of Antarctic explorers & scientist through outreach activities such as the Lyme Regis Fossil festival
  • Training early career researchers through master/PhD studentships in partnership with major UK Universities, post-Docs & EU fellowships, such as the Horizon 2020 Marie Curie scheme
