Petrology of Pliocene (?) Basalts of Curlew Valley (Box Elder Co.), Utah

Basalt outcrops in Curlew Valley consist of vii several flow remnants and eruptive centers situated along the valley margins. Basalt is also found in association with salic rocks that erupted in the central portion of The basalts are of probable Pliocene age and the valley. were erupted during a period of active extensional tectonics. Since their emplacement, and downfaulted. the basalts have been extensively eroded The present morphology reflects the erosional and depositional processes of prehistoric Lake Bonneville. Twelve samples were analyzed chemically for major oxides, trace elements, and rare-earth elements. The basalts form a hypersthene normative series ranging from olivine tholeiite to tholeiite. Based on chemical data, the basalts form three distinct groups. Comparison of the major oxides shows two of the groups forming a differentiation sequence separate from the third group. Trace element and rare-earth element data indicate that the three chemical groups are related to a common source but that two batches of magma probably emanated from this source. Pyrolite, spinel lherzolite, and garnet lherzolite were evaluated as hypothetical mantle materials from which a parent magma might be derived through partial melting. Based on rare-earth element profiles, garnet lherzolite appears to be the most likely source material for deriving the basalts. The trace element and rare-earth element data do not show any anomalies that would suggest contamination from crustal material. Comparison of chemical data shows that the Curlew Valley basalts are genetically similar to basalts from the Kelton and Rozel Point-Black Mountain areas, southwest and southeast of the study area, respectively. The Curlew Valley basalts are chemically similar to olivine tholeiites from the Snake River Plain and Blackfoot Reservoir areas in Idaho, but they do not show much similarity to basalts near Snowville, Utah, northeast of the study area. The Curlew Valley basalts are generally more iron rich and less alkalic than other basaltic rocks from the eastern Basin and Range Province

Charge Transfer in Poly (3-Hexylthiophene) / Titanium Dioxide Inverse Opals: Effects of Surface Passivation and Donor Concentration

Hybrid photovoltaics are attractive because of their low cost and ability to be applied onto flexible substrates. However defect states can trap charges and are undesirable. We investigate TiO2 inverse opals treated with titanium tetrachloride (TiCl4) and subsequently coated with poly(3-hexylthiophene) (P3HT) to elucidate the effect of surface passivation on the photoinduced charge transfer and polaron dynamics. The chemical, physical and morphological properties were characterized using UV-vis spectroscopy, reflectance microscopy, X-ray diffraction, Raman spectroscopy and scanning electron microscopy. Passivation resulted in increased wall thickness of the inorganic framework and crystallite size. Photoinduced absorption spectroscopy showed enhanced polaron absorptions and reduced polaron lifetimes with increased titanium tetrachloride concentration and reduced concentration of the solution from which the P3HT is cast. The 3D structure presents an opportunity to study the charge transfer within a percolated network

Politicising and depoliticising covid-19: four narratives the government used to manage the balance between taking credit and apportioning blame

Peter Kerr and Steve Kettell examine the politicising and depoliticising effects of the various stories that were deployed by the government in its response to the coronavirus crisis during its daily press briefings over a 2-month period between 16 March and 16 May 2020. They identify four key narratives: unprecedented government activism; working to plan; national security, wartime unity and sacrifice; and scientific guidance

The Brexit Religion and the Holy Grail of the NHS

The role of populism in mobilising support for Britain’s withdrawal from the European Union has been well noted. But a key feature of populist politics – the use of religious discourses – has been largely overlooked. This article addresses this gap by exploring the way in which the Leave campaign framed Brexit in quasi-religious and mythological terms. Three core themes are identified: (1) that the British ‘people’ had a unique role to play in global affairs; (2) that the sanctity of this special status was threatened by elites and migrants; (3) that the referendum gave voice to the sacred ‘will of the people’. These narratives were underpinned by a strategic discourse centring on claims that EU membership was exacerbating a crisis in health and social care. This myth was encapsulated by the so-called ‘Brexit bus’ campaign
