Multi-stage orogenic gold mineralization of the Pine Lake greenstone belt: evidence from the Seabee Gold Operation, Trans-Hudson orogen, northern Saskatchewan
… Glennie domain of the larger Paleoproterozoic Trans-Hudson orogen. At the Seabee Gold Operation, auriferous quartz veins are hosted within shear zones, such as the Santoy shear system, that are focussed along basalt-intrusion contacts, extending south onto the Fisher property. The systematics …

Seismic delineation of the southern margin of the middle Devonian prairie evaporite in the Elk Point Basin, south-central Saskatchewan
… crossing the salt collapse margin and the Trans-Hudson Orogen and the Wyoming Structural Province were analysed. Regional-scale gravity modeling showed that the transition from the Trans-Hudson Orogen to Wyoming Province was marked by deep-seated structures within the basemen. Detailed …

Metamorphic and Tectonic Evolution of the Paleoproterozoic Thompson Nickel Belt, Manitoba
… reworked during the Paleoproterozoic Trans-Hudson orogeny. This work represents the first comprehensive regional metamorphic study of the belt. Three nested metamorphic domains are present in the Thompson Nickel Belt which are elongate subparallel to the regional strike of the belt. …

The Geobiology of the Paleoproterozoic Belcher Group, Nunavut, Canada
… deep burial or strong deformation during the Trans-Hudson orogen. The 6-9 km thick Belcher Group includes a variety of shallow marine depositional environments, two distinct periods of volcanism, and a prograding submarine fan system. The rock types range from dolomitic carbonate platforms to …

Fluid Evolution and Structural Control on Uranium Deposits in Successor Basins in Northern Canada and Northern Australia
… metasomatism during regional metamorphism of the Trans-Hudson Orogen. The ore-forming fluids were likely derived from metamorphic remobilization of pre-existing U-rich basement rocks, and ascended upward along deep fracture systems that resulted from brittle reactivation of early ductile shear …

The Fraser Lakes Zone B U-Th-REE deposit and its host rocks : implications for pegmatite- and leucogranite-hosted U-Th-REE deposits in northern Saskatchewan, Canada
… decompression related to the ca. 1.9 to 1.8 Ga Trans-Hudson Orogen (THO). Examination of the pelitic gneiss host rocks at Fraser Lakes Zone B revealed that the area underwent high temperature (up to ~780°-800° C), low to medium pressure (max pressures of ~7-8 kbar), upper amphibolite to …

CHARACTERIZING THE AURIFEROUS SYSTEM AT PORKY LAKE WITHIN THE PINE LAKE GREENSTONE BELT, NORTHERN SASKATCHEWAN, WITH A FOCUS ON PETROGRAPHY AND MINERAL CHEMISTRY
… supporting an interconnected, multi-stage orogenic gold system throughout the belt. Lastly, we report new geochronology of a ca. 1851 Ma granodiorite that intrudes the Porky Lake Group, refining previous age constraints.
