Article
Full-text available
The provocative hypothesis that the Shinumo Sandstone in the depths of Grand Canyon was the source for clasts of orthoquartzite in conglomerate of the Sespe Formation of coastal California, if verified, would indicate that a major river system flowed southwest from the Colorado Plateau to the Pacific Ocean prior to opening of the Gulf of California...
Article
The growth of southern Laurentia has been attributed to the accretion of juvenile arc terranes during the successive 1.74-1.68 Ga Yavapai and 1.65-1.60 Ga Mazatzal orogenies. However, in light of the increasing importance of the ca. 1.49-1.40 Ga Mesoproterozoic Picuris orogeny, the tectonic setting in which the Mazatzal crustal province and its dis...
Conference Paper
Multiple unconformity-bound packages of metasedimentary rocks in central Arizona are key markers for models of Proterozoic crustal growth by accretionary orogenesis, but scattered exposures and limited geochronologic constraints have hindered regional correlations. Detrital zircon geochronologic data from these basin successions across a NW-SE tran...
Article
The formation of the Mojave crustal province has been a persistent enigma in models of the Proterozoic tectonic history of southwestern Laurentia. It is composed of similarly-aged 1.8–1.7 Ga rocks as the adjacent Yavapai province, yet shows evidence of much older (>2.2 Ga) lithospheric components in all isotopic systems. We present >700 new U-Pb an...
Article
Full-text available
The Sandia-Manzano and adjacent Los Piños mountains, the eastern uplift of the Rio Grande rift along the Albuquerque basin, expose a series of Paleoproterozoic and Mesoproterozoic plutons that intrude the 1.70-1.60 Ga Manzano Group within the Manzano thrust belt. This paper summarizes the age and tectonic setting of two distinct pulses of magmatism...
Article
Full-text available
For more than 25 yr, the Mazatzal orogeny has been a central component of virtually all tectonic models involving the Proterozoic rocks of the south-western United States. Recent recognition that some sedimentary sequences and some major structures are Mesoproterozoic rather than Paleoproterozoic has led to new questions about the nature, even the...
Article
Full-text available
Lithospheric growth of southwestern Laurentia during the Paleoproterozoic has been hypothesized to have involved addition of two dominantly juvenile crustal provinces: the 1.8–1.7 Ga Yavapai province and the 1.7–1.6 Ga Mazatzal province. Timing of assembly of these two crustal provinces has been stated to have occurred during the 1.72–1.68 Ga Yavap...
Article
Full-text available
The Paleoproterozoic Mojave and Yavapai crustal provinces in southwestern Laurentia contain evolved and juvenile crust, respectively, but the nature of the province boundary remains uncertain. 1.78-1.35 Ga crystalline basement rocks of the Mojave Province preserve an evolved isotopic signature reflecting an Archean crustal component in several isot...
Article
Full-text available
Growth of garnet and pyroxene in orthogneiss from the Athabasca granulite terrane (AGT), northern Saskatchewan, provides a model for progressive densification and strengthening of the lower continental crust with implications for the recycling and long-term evolution of continental crust. Two distinct assemblages and textures are preserved in grani...
Article
Full-text available
The Cora Lake shear zone (CLsz) is a 4–6 km wide localized high-strain zone that bisects the polydeformed Athabasca granulite terrane, northern Saskatchewan. It also coincides with the geophysical trace of the Snowbird tectonic zone. The CLsz represents a major lithotectonic and thermobarometric discontinuity within the exposure of >20 000 km2 of h...
Conference Paper
Deep crustal flow is a fundamental tectonic process that may serve to reduce topographic gradients, especially in overthickened collisional orogens. Recent studies have utilized numerical models and seismic interpretations, but generally in two dimensions. Although useful, two dimensional models can not fully characterize lower crustal flow or coup...

The goal of this project is to improve our understanding of the behavior of muscovite during in-vacuo heating. Muscovite is one of the most common minerals dated for geochronologic/thermochronologic via the Ar/Ar method, but the kinetics of degassing during laboratory heating are poorly constrained. With a greater kinetic understanding of Ar transport during in-vacuo heating, geologically meaningful, high-resolution thermochronologic data may be determined from step-heating.
