Abstract Deep geology of ancient continental crust can be difficult to access, with direct observation restricted to limited exposures. The age and composition of hidden geology can be gleaned from indirect isotopic modelling or via detrital minerals

Combined apatite Lu–Hf, U–Pb, and fission track (AFT) triple dating affords the opportunity to investigate the ~60 and 730°C thermal history of a study area. Here, we apply apatite triple dating to resolve the tempo of multiple thermo-tectonic e

Abstract Argyle is the world’s largest source of natural diamonds, yet one of only a few economic deposits hosted in a Paleoproterozoic orogen. The geodynamic triggers responsible for its alkaline ultramafic volcanic host are unknown. Here we show,

Abstract Passive continental margins (PCMs) represent the interface between the marine and terrestrial realms. However, topographic evolution of PCMs is often difficult to decipher due to paucity of the preserved geological record. Here, we report ur

The timing of deformation in ancient shear zones of the Akia Terrane, Greenland, is recorded by the Proterozoic Rb-Sr age of mylonitic biotite which is determined through collision cell laser ablation and inverse thermal history modelling.

Abstract Accurate chronology of climatic shifts is critical to understand the controls on landscape and species evolution. Unfortunately, direct dating of continental climate change is hindered by the scarcity of dateable terrestrial products evidenc

Abstract The Grenville Orogen, in North America, contains a belt of Proterozoic anorthosite massifs with an episodic emplacement history. These distinctive magmas reflect extensive fractional crystallization of plagioclase from a mafic magma and cont

Abstract The construction of ocean island basaltic volcanoes consists of a succession of eruptions, intrusions, and metamorphism. These events are often temporally ill‐constrained because the most widely used radiometric dating methods applicable t

The ~70 km-diameter Yarrabubba impact structure in Western Australia has previously been regarded as among Earth’s oldest meteorite craters, but has hitherto lacked absolute age constraints. Here, the authors determine a precise impact age of 2229
