Geology, geochemistry and geochronology of the Songwe Hill carbonatite, Malawi
(Elsevier for Geological Society of Africa, 2017-06-02)Songwe Hill, Malawi, is one of the least studied carbonatites but has now become particularly important as it hosts a relatively large rare earth deposit. The results of new mapping, petrography, geochemistry and geochronology ... -
An investigation into the development of toppling at the edge of fractured rock plateaux using a numerical modelling approach
(Elsevier for International Geosynthetics Society (IGS), 2017-03-24)The mechanisms controlling the onset of minor slope instability at the edges of rocky plateaux exhibiting lateral spreading phenomena are yet to be fully understood. Hypotheses have recently been introduced to explain the ... -
Pliocene-Pleistocene evolution of sea surface and intermediate water temperatures from the southwest Pacific
(Wiley & American Geophysical Union (AGU), 2016-06)Over the last 5 million years, the global climate system has evolved toward a colder mean state, marked by large-amplitude oscillations in continental ice volume. Equatorward expansion of polar waters and strengthening ... -
Mid Pleistocene foraminiferal mass extinction coupled with phytoplankton evolution
(Nature Publishing Group:, 2016-06-17)Understanding the interaction between climate and biotic evolution is crucial for deciphering the sensitivity of life. An enigmatic mass extinction occurred in the deep oceans during the Mid Pleistocene, with a loss of ... -
The geological setting of the Hemerdon W–Sn deposit
(Maney Publishing for Institute of Materials, Minerals and Mining (UK); Australasian Institute of Mining and Metallurgy (AusIMM), 2017-03)The Hemerdon W-Sn deposit, being worked at Drakelands Mine near Plymouth by Wolf Minerals is centred upon a subvertical, NNE-SSW striking, 100+ m wide Early Permian granite dyke hosted by Devonian metasedimentary and ... -
Homogenisation of sulphide inclusions within diamonds: A new approach to diamond inclusion geochemistry
(Elsevier, 2017-05-08)metal sulphide (BMS) inclusions in diamonds provide a unique insight into the chalcophile and highly siderophile element composition of the mantle. Entombed within their diamond hosts, these provide a more robust (closed ... -
Charcoal evidence that rising atmospheric oxygen terminated Early Jurassic ocean anoxia
(Nature Publishing Group, 2017-05-12)The Toarcian Oceanic Anoxic Event (T-OAE) was characterized by a major disturbance to the global carbon(C)-cycle, and depleted oxygen in Earth’s oceans resulting in marine mass extinction. Numerical models predict that ... -
Orbital forcing of the Paleocene and Eocene carbon cycle
(American Geophysical Union, 2017-05-04)Multimillion-year proxy records across the Paleocene and Eocene show prominent variations on orbital time scales. The cycles, which have been identified at various sites across the globe, preferentially concentrate ... -
The rare earth elements: demand, global resources, and challenges for resourcing future generations
(Springer Verlag (Germany), 2017-04-20)The rare earth elements (REE) have attracted much attention in recent years, being viewed as critical metals because of China’s domination of their supply chain. This is despite the fact that REE enrichments are known to ... -
Responsible sourcing of critical metals
(Taylor & Francis, 2017-03-30)We use a wider range of specialist raw materials in our manufactured goods than ever before. Many of these are mined in just small quantities, of tens to thousands of tons per year, and that means that a small number of ... -
Incorporating criticality into Life Cycle Assessment for rare earth production
(Taylor & Francis, 2017-04-05)Rare earth elements (REE) have a broad and expanding range of uses in low carbon energy technologies, from wind turbines, to batteries, catalysts and electric cars. Concerns about the future supply of individual REE, such ... -
Base of the Toarcian Stage of the Lower Jurassic defined by the Global Boundary Stratotype Section and Point (GSSP) at the Peniche section (Portugal)
(International Union of Geological Sciences, 2016-09)The Global Stratotype Section and Point (GSSP) for the base of Toarcian Stage, Lower Jurassic, is placed at the base of micritic limestone bed 15e at Ponta do Trovão (Peniche, Lusitanian Basin, Portugal; coordinates: ... -
Multiple Osmotic Stress Responses in Acidihalobacter prosperus Result in Tolerance to Chloride Ions
(Frontiers Media, 2017-01-05)Extremely acidophilic microorganisms (pH optima for growth of ≤3) are utilized for the extraction of metals from sulfide minerals in the industrial biotechnology of "biomining." A long term goal for biomining has been ... -
The DeepMIP contribution to PMIP4: Experimental design for model simulations of the EECO, PETM, and pre-PETM (version 1.0)
(European Geosciences Union (EGU) / Copernicus Publications, 2017-02-23)Past warm periods provide an opportunity to evaluate climate models under extreme forcing scenarios, in particular high (> 800ppmv) atmospheric CO2 concentrations. Although a post hoc intercomparison of Eocene (∼ 50 Ma) ... -
The Bottaccione section at Gubbio, central Italy: a classical Paleocene Tethyan setting revisited
(Schweizerbart Science Publishers, 2015-08-03)The Upper Cretaceous to Paleocene succession cropping out at the Bottaccione section (Gubbio, central Italy) represents a classical Tethyan setting that served as a standard for the construction of the geomagnetic polarity ... -
The breakdown of static and evolutionary allometries during climatic upheaval
(University of Chicago Press, 2017)The influence of within-species variation and covariation on evolutionary patterns is well established for generational and macroevolutionary processes, most prominently through genetic lines of least resistance. However, ... -
