Monazite Geochronology of the Madison Mylonite Zone and Environs, Southwestern Montana: With Implications for Precambrian Thermotectonic Evolution of the Northern Wyoming Province
Neoarchean thermotectonism at in the northern Wyoming province is preserved in metamorphic zircon rims and monazite growth throughout the Snowy shear zone (SSZ) and the Madison mylonite zone (MMZ), South Madison Range, Montana. Comparison of U-Pb and U-Th-Pb ages yielded by monazite grains from …

Seismic delineation of the southern margin of the middle Devonian prairie evaporite in the Elk Point Basin, south-central Saskatchewan
… 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 gravity modeling of a shorter …

An investigation of a polymetamorphic terrain using <sup>40</sup>Ar-<sup>39</sup>Ar geochronology
… south-western Montana region of the Precambrian Wyoming Province was believed to have undergone at least three separate periods of metamorphism: M1- granulite facies in the Archaean, M2 - amphibolite facies in the Early Proterozoic, and M3 - greenschist to epidote-amphibolite facies in the …
