Challenging the sensitivity limits of paleomagnetism : magnetostratigraphy of weakly magnetized Guadalupian-Lopingian (Permian) limestone from Kyushu, Japan
(2015-01-15) - Journal article,
Despite their utility for bio- and chemostratigraphy, many carbonate platform sequences have been difficult to analyze using paleomagnetic techniques due to their extraordinarily weak natural remanent magnetizations (NRMs). ...
Controlling for the effects of information in a public goods discrete choice model
(2016-03) - Journal article,
This paper develops a reduced form method of controlling for differences in information sets of subjects in public good discrete choice models, using stated preference data. The main contribution of our method comes from ...
Not so non-marine? Revisiting the Stoer Group and the Mesoproterozoic biosphere
(2017-06-13) - Journal article,
The Poll a’Mhuilt Member of the Stoer Group (Torridonian Supergroup) in Scotland has been heralded as a rare window into the ecology of Mesoproterozoic terrestrial environments. Its unusually high molybdenum concentrations ...
Stable vanadium isotopes as a redox proxy in magmatic systems
(2016-10-26) - Journal article,
Recycling pathways of multivalent elements, that impact our understanding of diverse geological processes from ore formation to the rise of atmospheric oxygen, depend critically on the spatial and temporal variation of ...
The isotope geochemistry of zinc and copper
(2017-01-31) - Journal article,
Time-resolved optically stimulated luminescence and spectral emission features of α-Al2O3:C
(2015) - Journal article,
Abstract This report is concerned with the influence of measurement temperature on luminescence lifetime and on the spectral emission features of luminescence from α-Al2O3:C. The lifetimes were determined from time-resolved ...
Copper isotope evidence for large-scale sulphide fractionation during Earth’s differentiation
(2015-06-04) - Journal article,
Abstract The differentiation of Earth into a metallic core and silicate mantle left its signature on the chemical and isotopic composition of the bulk silicate Earth (BSE). This is seen in the depletion of siderophile ...
Multiple Palaeoproterozoic carbon burial episodes and excursions
(2015-08-15) - Journal article,
Abstract Organic-rich rocks (averaging 2–5% total organic carbon) and positive carbonate-carbon isotope excursions ( δ 13C > + 5‰ and locally much higher, i.e. the Lomagundi-Jatuli Event) are hallmark features of ...
Neoproterozoic crustal growth of the Southern Yangtze Block : Geochemical and zircon U–Pb geochronological and Lu-Hf isotopic evidence of Neoproterozoic diorite from the Ailaoshan zone
(2015-09) - Journal article,
Abstract Neoproterozoic felsic igneous rocks associated with mafic-ultramafic bodies along the margins of the Yangtze Block, South China, can be used to constrain the continental crustal growth and secular evolution of the ...
In what sense ‘distinctive’? The search for distinction amongst cross-border student migrants in the UK
(2015-08) - Journal article,
This paper offers a geographical analysis of the concept of ‘distinction’ in relation to student mobility within the UK. The analysis in this paper is based primarily on interviews with Scottish students who have chosen ...
