CM carbonaceous chondrites display a range of alteration (aqueous alteration) from slightly altered (CM2.5) to most altered (CM2.0). They are of particular interest in understanding early solar system evolution because they are made of a mixture of mineral grains that formed at …

Mass extinctions are important events for the evolution of life on Earth but often the mechanisms behind them are poorly understood. The Eocene - Oligocene Transition (EOT) had a profound and lasting influence on global climate and, though not one of the “big 5” mass extinction …
Ground improvement work is crucial in enhancing the characteristics of weak soils commonly encountered in Civil Engineering, and one such technique commonly used is vibro-stone columns. An assessment of the effectiveness of such an approach is critical to determine whether the q…
Ostracod assemblages from samples collected through the Turonian Stage of the Late Cretaceous from Dover, Kent, south-east England, consist of one hundred and three species group taxa. These are described and illustrated. This represents a significant increase in the knowledge o…
Glasgow contains many buildings made from local ‘blond’ sandstones that are showing the legacy of 150 years of urban weathering and this decay may accelerate as climate changes in the future. Most of the blond sandstones are Carboniferous in age and comprise of micaceous quartz …
Reservoirs of South Brae Oilfield comprise a 1540m sequence of Upper Jurassic submarine fan sandstones and conglomerates. The diagentic history of the reservoir between 3684 and 4202m was studied using petrographic, geochemical, fluid inclusion thermometry and isotope techniques…
The late Pliocene is marked by the end of an interval of warm, relatively stable global climate and a secular shift into a bipolar glaciated world. The intensification of northern hemisphere glaciation (iNHG) central to this climatic transition was accompanied by a decrease in a…
This dissertation introduces the habitat use and spatial-temporal distribution of Cuvier’s beaked whale (Ziphius cavirostris, Cuvier, 1823) in the Bay of Biscay, from surveys carried out by the Biscay Dolphin Research Programme between 1995 and 2007. I have analysed the spatio-t…
This thesis discusses a comprehensive study of the structure and properties of selected stacked perovskites using non-ambient powder and single-crystal x-ray diffraction, powder neutron diffraction, birefringence microscopy and dielectric spectroscopy. The major portion of this …
The impact of a 1 in 40 year flood on the morphology and sedimentology of the sandy braided South Saskatchewan River, Canada was assessed. Comparison of 2004 - 2007 repeat GPR surveys and the production of DEMs of difference allowed quantification of the initial and long-term 20…
There has recently been a steady increase in the number of licenses granted for the abstraction of water from the Chalk aquifer beneath London to supply "open loop" geothermal systems (Environment Agency, 2007). However, there has been little research conducted on how the water …
This project compares palaeo-oxygenation related features of lower Cretaceous rocks from the shallow sea muds of the Gault Clay (south east England) and Niveau Pacquier and Briestroffer sequences (south east France), and the Tarfaya Basin upwelling-zone Amma Fatma sediments (Mor…
The search for life beyond Earth, and on Mars in particular, is one of the key points of astrobiology research. However, space missions are expensive and time-consuming. Simulating such missions at analogue sites on Earth can thus save time and money whilst working in natural se…
Future robotic exploration missions within the Solar System, focussing on either scientific discovery or the emerging field of In-Situ Resource Utilisation (ISRU), shall require the development of technologies which are capable of exploring to ever-greater depths beneath the pla…
Abrupt lateral changes in thrust geometry occur in many mountain-building fold-thrust belts. Whilst many works have dealt with palinspastic reconstructions and transport-directionparallel balanced cross-sections, far fewer show a full three-dimensional architecture, or examine h…
The geological and geodynamic processes that have controlled the evolution of the Northumberland Trough Region in Northern England have been investigated to expand understanding of the evolution of continental extensional basins. The region has experienced a number of extensiona…
Fast-spreading mid-ocean ridges (MOR) are underlain by a thin, quasi-steady-state melt or crystal mush body at the base of the sheeted dykes, referred to as the axial melt lens (AML). Although the AML is thought to play a key role in the development of MOR basalts (MORB), debate…
The migration of hydrocarbons on formation and accumulation on commercially viable oil and gas deposits/reserves/reservoirs. Reflection 2D/3D seismic data can be used to identify the position of these fluids in the subsurface and analyse their habitat and pathways in the context…
