Biography

I am fascinated by the workings of our planet and how processes operating in its deep interior influence those at its surface. My research is broad in scope and embraces mantle and volcanic rocks ranging from 3.5 billion to <1 year in age. The advancement of knowledge made by my research group has been accomplished by combining detailed field observations in remote parts of Africa, South and North America, Russia plus the Atlantic and Pacific Oceans with analytical studies of volcanic rocks, geophysical and numerical investigations. This rigorous approach has allowed me to address provocative and timely scientific questions related to global geodynamic processes. A large recent campaign of my research group has been focused on the cycling of volatiles. This is now being expanded to look at the origins of critical metals in our new REE-LITH project.

Research Interests

Linking Earth's deep interior with its surface evolution

My research group is focused on both field and laboratory (petrological, experimental, geochemical and geophysical) investigations in order to understand melt generation in the Earth’s crust and mantle and how this relates to surface processes. Key questions that our current research seeks to address fall into 4 major fields:

1. How does Earth's rigid outer shell modulate the release of volatiles from our planet's deep interior ?

On-going studies of fragments of deep-sourced mantle material (xenoliths) are providing important insights into the formation of the Earth’s lithosphere and how this large reservoir acts as a major sink and also a source for volatiles (CO2, H2O, S, F) released during volcanism. We have recently quantified the mass of the lithosphere beneath major tectonic settings and this has allowed us to calculate internally consistent estimates of multiple volatiles. Our studies reveal that the ancient cores of Earth's continents are a major sink in global volatile cycles. More work is now required to reduce the uncertainties in these estimates.

2. Ocean Islands: How do they form and what controls volcanism?

Ocean islands are sites of some of the world’s most active volcanism.

  • Research on basaltic lavas from the islands of Tristan da Cuhna and Trindade in the South Atlantic has provided constraints on the role of recycled delaminated subcontinental lithosphere in the genesis of ocean-island basalts.
  • Mid ocean ridges are anchored to mantle plumes by deep seated melt channels. Galapagos is an archetypal example of this type of interaction: our findings suggest that twVariation in lithospheric thickness (depth to top of melt column) and magma type in the Galapagos archipelago (purple stars are depleted tholeiites). From Gibson & Geist (2010).o-phase rather than solid-state flow is important (Gibson et al., 2015).
  • A recent detailed investigation of alkaline and tholeiitic lavas from Santiago in the Galápagos has revealed that their compositions are as diverse as for any other island in the archipelago or indeed any other ocean island.
  • By combining new geochemical data with published geophysical data our research has led to an understanding of the causes of widespread active volcanism throughout Galápagos: significant lithospheric thinning in the NE of the archipelago explains the generation of volcanism away from the main axis of the Galápagos plume (Gibson & Geist, 2010)

 

Charles Darwin: some of the earliest insights into volcanic islands

Collage galapagos

 

Research in Galápagos was initiated in 2007 in collaboration with D. Geist, G. Estes, T. Grant, D. Norman and S. Herbert. The main focus of this research was to establish Darwin’s route on Santiago  -- formerly known as James Island -- in 1835 (Herbert et al., 2008). This is the island where Darwin made some of his most significant observations on volcanic rocks and led to his theory of gravitational settling as a cause of magmatic diversity (Gibson, 2009). 

Here's a link to some images from the Cambridge-Quito expedition to Galapagos in 2017 and another to the Cambridge-Idaho expedition to Galapagos in 2008

 

3. Large Igneous Provinces: What processes are responsible for the most voluminous outpourings of magma in our planet's history?

These represent the most voluminous emplacements and outpourings of maEtendeka flood basalts, NW Namibiagma that have occurred on Earth’s during its 4.5 billion year evolution. They frequently coincide with the break-up of supercontinents (e.g. the Paraná-Etendeka and Deccan flood-basalt provinces) and are formed by the arrival of a large, up to 2000 km in diameter, thermal anomaly on the base of Earth’s lithosphere. These so-called mantle plumes are thought to be derived from thermal boundary layers deep within the Earth, such as the 2700 km core-mantle boundary.

  • Our detailed and systematic geochemical studies, together with high pressure and temperature experiments, on high Fe-picrites (undertaken in collaboration with E. Takahashi, Tokyo; J. Tuff, Oxford) have shown that garnet pyroxenite, probably derived from subducted lithospheric mantle, is present within upwelling mantle plumes.
  • Our research has also documented the longevity of volcanism associated with the initial impact of the Tristan mantle plume and it’s role in the opening of the South Atlantic. fossilized magma chambers
  • Studies of olivine-hosted melt inclusions reveal that primitive melts in flood basalt provinces are homogenised prior to cooling and crystallisation in deep-seated magma chambers in the Earth's crust (Jennings et al., 2017).

 

4. Remote sensing of rare-earth element deposits

An exciting collaboration with Dr Teal Riley (British Antarctic Survey) and Dr Graham Ferrier (University of Hull) examined how novel remote sensing techniques can be used to locate rare-earth element deposits. For an insight into some of our findings from this innovative new project click here. Some of our results on global carbonatite deposits can be found in a recent paper by Neave et al. (2016).
