TL;DR: In this article, a 4417 6 Myr old zircon in lunar breccia sample 72215,195 was reported, which provides a precisely determined younger limit for the solidification of the Lunar Magma Ocean.

TL;DR: In this article, the authors graphically summarize the evolution from the Earth's core to its atmosphere, from the Neoarchaean to the Mesoproterozoic eras (specifically 3.0-1.2 Ga), to reveal intriguing temporal relationships across the various spheres of the Earth system.

TL;DR: In this article, the deformation-related microstructure of an Indian Ocean zircon hosted in a gabbro deformed at amphibolite grade has been quantified by electron backscatter diffraction.

TL;DR: In this article, panchromatic and wavelength cathodoluminescence (CL) was combined with quantitative rare earth element (REE) ion microprobe analyses to demonstrate modification of zircon REE chemistry within the areas of crystal plasticity.

TL;DR: In this paper, the phase relations of ZrSiO4 polymorphs and associated dissociation products under extreme conditions using available empirical and theoretical constraints are presented. And a conceptual framework for a zircon-based approach to extreme thermobarometry that incorporates both direct observation of high-P and high-T phases, as well as inferences for the former existence of phases from orientation relationships in recrystallised products, a concept referred to here as "phase heritage".
