TL;DR: In this paper, the authors present 257 δ 44 / 40 Ca and 131 δ 26 Mg measurements, along with [Mg], [Mn] and [Sr] data, from carbonates of the Ediacaran-aged Wonoka Formation (Fm.) of South Australia to bring new isotope systems to bear on understanding the Shuram excursion.

TL;DR: This article used whole-rock Sm−Nd isotope systematics of 79 Archean granitoids from the eastern Kaapvaal craton, southern Africa, to delineate lithospheric boundaries and to constrain the timescale of crustal growth, assembly and geochemical differentiation.

TL;DR: In this article, the potential petrogenetic link between a crystal-poor rhyolite (the Rhyolite Canyon Tuff) and its associated subvolcanic intrusion and crystal-rich post-caldera lavas from Turkey Creek, Arizona (USA), is examined using zircon chemical abrasion-thermal ionization mass spectrometry U-Pb geochronology and inductively coupled plasminetry trace element analyses.

TL;DR: In this article, high-precision ID-TIMS U-Pb zircon geochronology was combined with numerical thermal simulations to evaluate emplacement rates, test different emplacements models, inform zircoin age interpretations and evaluate the potential for melt storage during construction of the Mt. Capanne pluton.

TL;DR: The authors showed that the magma solidified in the crust within just 10-40 thousand years of being injected into the crust, implying that the time window for an eruption was short.
