Palaeoceanography students newsletter article published.

The students: Paul Bridger, Sinéad Lyster and Abigail Hunt discuss their experiences of using an ocean core replicate during a practical for the Palaeoceanography course (GeolGG17/M018). The core covers an interval of dramatic climate change around 55.8 million years ago, termed the Paleocene-Eocene Thermal Maximum (PETM). The students studied the colour changes in the core replica, plotted percent carbonate data and answered a series of questions to determine sedimentological changes through this interval. More...

2016-EGU Award

EGU 2016 Awards: Louis Néel Medal.

On 19 April, Phil Meredith was awarded the 2016 Louis Néel Medal at the European Geosciences Union Assembly in Vienna. The award recognises outstanding achievements in rock magnetism, rock physics and geomaterials. In his citation, Ian Main, from the University of Edinburgh, highlighted how Phil has pioneered an entirely new, holistic approach to experimental rock physics and how the rock-physics community has benefited enormously from his unselfish co-operation in research: “He is a lively, deeply thoughtful and generous collaborator, serious about his work, but fun to be with.” More...

Precambrian Research Group


The Precambrian is the informal name for the first 90% of Earth history during which life began its incredibly long journey towards biological complexity. 


This journey culminated in the appearance and diversification of animals between about 750 and 540 million years ago. Sedimentary rocks become increasingly scarce the further back in time one looks. For this reason, Precambrian studies are multidisciplinary by necessity, piecing together clues from a range of fields: geochemistry, palaeobiology, biochemistry, sedimentology, genetics and a range of earth system models (atmospheric, ocean circulation, climate and biogeochemical).

Our research group primarily uses the chemical, mineral and isotopic composition of sedimentary rocks to reconstruct earth system evolution during the two billion year interval from the end of the Archaean Eon (about 2500 million years ago) to the beginning of the Phanerozoic Eon (about 540 million years ago). During this Proterozoic Eon, extraordinary perturbations occurred to our planet’s surface environment. Some disturbances were extreme but transient, such as the ‘Snowball Earth’ intervals of global glaciation. Others caused irreversible changes that shaped the modern earth system, such as the ‘Great Oxidation Event’ and the ‘Neoproterozoic Oxygenation Event’ without which we would not be here today.
