Lectures offered by Professor Manning Lecture A: Mineral solutions to global problems The world faces tremendous challenges to resolve the problems associated with climate change and food supply. In both of these, minerals have a vital role to play. To achieve carbon sequestration targets of up to 8 gigatonnes per year, we have to consider reactions that may take place on a global scale, and one way to do this is to understand and exploit those that take place in soils, recognising the role of plants as a carbon sink that links the soil and the atmosphere. To provide the bottom billion, the poorest of the worlds population who struggle to raise subsistence crops let alone commodity crops, we need to exploit the natural processes by which soil minerals provide essential nutrients as an appropriate companion to conventional fertiliser use. In these and other areas, minerals have a vital role to play in sustaining the human race. Lecture B: Minerals in biological systems As a mineralogist surrounded by biologists, I am often asked what do minerals do? Despite the widespread perception that they just sit in glass cases in museums, minerals are of course dynamic components of the biosphere, as any creature with teeth, a skeleton or a shell can tell you. Even the silent plants depend on minerals within their biomass to perform specific functions on which they depend for their existence. What is remarkable is the way in which biological systems influence the rates of growth (and dissolution) of minerals. For example the antlers of a red deer, cast and regrown annually may weigh several kg, requiring ingestion and mobilisation of normally poorly soluble Ca and P on a timescale that is instant from a geological point of view. There are many other examples of remarkably rapid mineral reactions within both the plant and animal kingdoms, and of course microbes also interact closely with mineral systems. Lectures offered by Professor Fallick Lecture A: The oxygen and hydrogen stable isotope geochemistry of gemstones Gem deposits offer particularly interesting challenges to the geologist: because they are relatively rare, unusual circumstances are necessary for their formation. Stable isotope geochemistry is one of the tools with which we can investigate these exceptional geological conditions. Apart from the intrinsic scientific interest of understanding formation mechanisms and conditions, such research can also elucidate genetic models to guide exploration and exploitation strategies, and identify diverse contributions to placer deposits. As an aid in constraining provenance, stable isotope ratios may have application in fingerprinting conflict minerals and materials. The stable isotope (18O/16O; D/H) composition of silicate and oxide minerals is usually a function of the temperature, isotopic characteristics and chemistry of the parental fluid from which they precipitated. The oxygen isotope fractionation factor between the fluid and the mineral depends on the environment of chemical bonding in a reasonably well-understood way. The application of such concepts to the precious stones emerald, ruby and sapphire is now established, and progress is being made with newer favourites such as red spinel and green garnet (tsavorite, tsavolite). The approach has proven particularly informative for semi-precious varieties such as agate and amethyst. Lecture B: Planet Earths mid-life crisis: Carbon isotopes, concretions and the Great oxidation event Around 2.2 billion years ago, the Earth experienced a series of dramatic upheavals which accompanied the transition from a reducing to an oxidising ocean/atmosphere system. The global carbon cycle was perturbed to an extent unparalleled before or since, with the changes documented in the stable carbon isotope record of carbonate (13Ccarb). From concretions in sediments, there is evidence that the manner in which organic matter is remineralised underwent radical change. However, the exact sequence of events leading to this  greatest pollution event of all time (Lovelock) is not yet clear, and several aspects are paradoxical. It is an open question whether there was one or several excursions to high (13Ccarb); the end of the high 13C record is reasonably well-established at 2056 6Ma, but its inception is not well defined, so that only a minimum duration (~ 140 my) is known. The interplay of the records of oxidised carbon (as carbonate) and reduced carbon (as organic matter) is especially problematic. Recent drilling in Arctic Russia by the International Continental Scientific Drilling Program FAR-DEEP Consortium has produced a marvellous new archive of 3.6km of drillcore with which these and other issues are being addressed.
