Time will tell: Secular change in metamorphic timescales and the tectonic implications
The pressure-temperature-time (PTt) evolution of metamorphic rocks is directly related to
geodynamics as different tectonic settings vary in their thermal architecture. The shapes of …

[HTML][HTML] A geochronological review of magmatism along the external margin of Columbia and in the Grenville-age orogens forming the core of Rodinia
A total of 4344 magmatic U-Pb ages in the range 2300 to 800 Ma have been compiled from
the Great Proterozoic Accretionary Orogen along the margin of the Columbia/Nuna …

[HTML][HTML] On the enigmatic mid-Proterozoic: Single-lid versus plate tectonics
Abstract The mid-Proterozoic (ca. 1850–850 Ma) is a peculiar period of Earth history in many
respects: ophiolites and passive margins of this age are rare, whereas anorthosite and A …

A template for an improved rock-based subdivision of the pre-Cryogenian timescale
The geological timescale before 720 Ma uses rounded absolute ages rather than specific
events recorded in rocks to subdivide time. This has led increasingly to mismatches between …

[HTML][HTML] Detrital zircon U–Pb age analysis of last glacial loess sources and proglacial sediment dynamics in the Northern European Plain
Loess deposits along the northern fringe of the European loess belt potentially record past
changes in dust emission from areas proximal to former ice sheets. Recent chronologies …

Geologic, geomorphic, tectonic, and paleoclimatic controls on the distribution and preservation of Chicxulub distal ejecta: A global perspective
Abstract The Cretaceous-Paleogene Boundary (KPB), the only known global impact ejecta
layer, resulted from the 66 million years ago Chicxulub Impact Event. KPB is well …

[HTML][HTML] Eurasian Ice Sheet derived meltwater pulses and their role in driving atmospheric dust activity: Late Quaternary loess sources in SE England
The role of Quaternary ice sheet fluctuations in driving meltwater pulses and ocean
circulation perturbations is widely acknowledged. What is less clear is the role of these …

[HTML][HTML] Geochronological constraints for a two-stage history of the Sveconorwegian rare-element pegmatite province formation
Most pegmatites of southern Norway seem to be derived from anatectic melting of
metamorphic rocks during the Sveconorwegian orogeny rather than to be highly evolved …
