Secular evolution of continents and the Earth system
Understanding of secular evolution of the Earth system is based largely on the rock and
mineral archive preserved in the continental lithosphere. Based on the frequency and range …

The Columbia supercontinent: Retrospective, status, and a statistical assessment of paleomagnetic poles used in reconstructions
The proposal that a Paleo-Mesoproterozoic supercontinent, Columbia, preceded the
existence of Rodinia was forwarded in 2002. A similar proposal that same year provided a …

Crustal melting and suprasolidus phase equilibria: From first principles to the state-of-the-art
Partial melting is the fundamental process by which juvenile crust was produced from the
mantle and subsequently reworked to become the stable, compositionally-differentiated …

Multispecies diffusion of yttrium, rare earth elements and hafnium in garnet
We report experimental data for Y, La, Lu and Hf diffusion in garnet, in which diffusant
concentrations and silica activity have been systematically varied. Experiments were …

Indenter tectonics in the Canadian Shield: A case study for Paleoproterozoic lower crust exhumation, orocline development, and lateral extrusion
D Corrigan, D van Rooyen, N Wodicka - Precambrian Research, 2021 - Elsevier
There are lingering questions about how far back in geologic time plate tectonic processes

Contrasting styles of lower crustal metamorphism from a granulite suite of rocks from Angul, Eastern Ghats Belt, India: implications for the India–Antarctica Correlation
The present work is focussed on a suite of high-grade rocks including mafic granulite,
aluminous granulite, khondalite, charnockite, and augen gneiss along with medium-grade …

Atoll garnet: insights from LA-ICP-MS trace element mapping
Atoll garnets are uncommon features that have been recognized in contrasting metamorphic
environments worldwide, but their origin remains largely debated. Several models have …

Decoupling of metamorphic zircon U-Pb ages and PT paths in the Dunhuang metamorphic complex, northwestern China
Y Si, R Ge, T Zhou, Y Wang - Precambrian Research, 2022 - Elsevier
U-Pb dating of metamorphic zircon is commonly used to determine the timing of high-grade
metamorphism, but linking zircon U-Pb ages to metamorphic PT paths can be challenging …

Neoproterozoic extension and decompression in the northern Eastern Ghats Province, India: Mid-crustal signature of Rodinia break-up?
Abstract The Eastern Ghats Province (EGP) of India is considered to have been a part of the
supercontinents Rodinia and Gondwana at c. 1.0 Ga and 500 Ma, respectively. A range of …

Long-lived anatexis in the exhumed middle crust of the Torngat Orogen: Constraints from phase equilibria modeling and garnet, zircon, and monazite geochronology
Middle and lower orogenic crust exposed at the Earth's surface represent an exceptional
opportunity to investigate accretionary and collisional processes in various tectonic settings …
