Zircon Th/U ratios in magmatic environs by Kirkland, Chris, Smithies, R., Taylor, Richard, Evans, Noreen, McDonald, B.

“…A comprehensive database of zircon composition in West Australian magmatic rocks reveals negative correlations between both U and Th zircon/whole rock ratio and the zircon saturation temperature, with the observed change with temperature less for U(zircon/whole rock) than for Th(zircon/whole rock). …”

Deformation-related microstructures in magmatic zircon and implications for diffusion by Reddy, Steven, Timms, Nicholas Eric, Hamilton, P. Joseph, Smyth, Helen

“…Tectonic stresses within the compressional Sunda Arc at the time of magmatism are consideredto be the probable driver for low-strain deformation of the cumulate in the late stages of initial crystallisation.These results provide the first evidence of crystal plastic dislocation creep in zircon associated with magmatic crystallisation and indicate that the development of crystal-plastic microstructures in zircon is not restricted to high-strain rocks. …”

Mesoproterozoic intraplate magmatic ‘barcode’ record of the Angola portion of the Congo Craton: Newly dated magmatic events at 1505 and 1110 Ma and implications for Nuna (Columbia) supercontinent reconstructions by Pisarevsky, Sergei, Ernst, R., Pereira, E., Hamilton, M., Rodriques, J., Tassinari, C., Teixeira, W., Van-Dunem, V.

“…The identification of these three Mesoproterozoic magmatic events (ca. 1505, 1380, and 1110 Ma) represent an initial magmatic ‘barcode’ for this portion of Congo Craton (and formerly connected São Francisco Craton), which can be compared with the magmatic ‘barcode’ record of other blocks to identify former nearest neighbors in the Precambrian supercontinent Nuna (also known as Columbia).Specifically, a 1502 ± 5 Ma U–Pb TIMS baddeleyite age has been obtained for the prominent Humpata dolerite sill which is part of a wider sill province in SW Angola portion of the Congo Craton. …”

The relationship of Palaeozoic metamorphism and S-type magmatism on the paleo-Pacific Gondwana margin by Scott, J., Muhling, J., Fletcher, Ian, Billia, M., Palin, J., Elliot, T., Gunter, C.

“…This age overlaps with the initiation of regional Karamea S-type granitic magmatism. Although estimated metamorphic conditions were insufficient for large amounts of melt to have been produced from Bonar Range pelites (calculated melt volumes are < 10%), they do provide evidence consistent with widespread heating and partial melting in the deeper crust.This heating episode was contemporaneous with partial melting in Fiordland (New Zealand) and West Antarctica, although Mesozoic thermal and deformational events complicate the Palaeozoic record in both those areas. …”

A Palaeoproterozoic tectono-magmatic lull as a potential trigger for the supercontinent cycle by Spencer, Christopher, Murphy, J., Kirkland, Chris, Liu, Y., Mitchell, R.

“…An appraisal of the global geologic record from about 2.3 to 2.2 billion years ago demonstrates a Palaeoproterozoic tectono-magmatic lull. During this lull, global-scale continental magmatism (plume and arc magmatism) and orogenic activity decreased. …”
