Laurentia is the craton that forms the Precambrian core of North America and was a major
continent throughout the majority of the Proterozoic following its amalgamation 1.8 billion …

This study examines the Paleoproterozoic history of supracrustal rocks in the western
Canadian Shield to better inform the tectonic history of northern Laurentia. Samples for …

Mylonitic micaschists in the south-eastern sector of the Posada-Asinara Shear Zone in the
Axial Zone of the Sardinia Variscan chain were investigated for the reconstruction of their …

Corona textures, characterized by specific mineral assemblages as layers between existing
phases, are frequently observed in high-grade metamorphic rocks. The mechanisms of …

This study characterizes the polyphase tectonometamorphic history of a major shear system
in the Rae craton, the Howard Lake shear zone (HLsz), which exhumed high-grade rocks in …

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 …

Canada's northern cratons record a complex poly‐metamorphic evolution in response to
multiple orogenic events. The Snowbird Tectonic Zone (STZ), the principal suture between …

Garnet with complex, discontinuous zoning is a common occurrence in metamorphic
terrains, and the relationship between major and trace element zoning can provide insight …

The study of Paleoproterozoic sedimentary basins is critical to inform aspects of craton
development during some of Earth's earliest supercontinent cycles. The∼ 1.9 Ga Nonacho …

Abstract The Nonacho Group comprises six formations of continental clastic rocks that were
deposited between 1.91 and 1.83 Ga. The Nonacho Group is part of a broader assemblage …
