The Colorado Proterozoic province is separated from Archean rocks of the Wyoming province by a major structural boundary, the Cheyenne belt. Proterozoic rocks south of the Cheyenne belt are exposed in the Sierra Madre, Medicine Bow Mountains, and Laramie Range of southern Wyoming. They consist of metavolcanic units, metagraywacke, pelitic schist and gneiss, amphibolite, and felsic to mafic intrusive rocks that locally resemble rocks of central Colorado. North of the Cheyenne belt, Archean… 

Evidence for an inverted metamorphic gradient associated with a Precambrian suture, southern Wyoming

An inverted metamorphic gradient associated with the northern mylonite zone of the Cheyenne belt, a deeply eroded Precambrian suture in southern Wyoming, has been documented within metasedimentary

New models for Paleoproterozoic orogenesis in the Cheyenne belt region: Evidence from the geology and U-Pb geochronology of the Big Creek Gneiss, southeastern Wyoming

The disputed age of the deep crust of the Colorado Province is central to hypotheses for Paleoproterozoic crustal growth in the region. We studied the high-grade Big Creek Gneiss, southeastern

A new view of an old suture zone: Evidence for sinistral transpression in the Cheyenne belt

The type locality of the Archean–Paleoproterozoic suture zone in the southern Rocky Mountains is marked by a series of subvertical shear zones collectively called the Cheyenne belt. The Cheyenne belt

Reactivation of the Archean-Proterozoic suture along the southern margin of Laurentia during the Mazatzal orogeny: Petrogenesis and tectonic implications of ca. 1.63 Ga granite in southeastern Wyoming

The presence of ca. 1.63 Ga monzogranite (the “white quartz monzonite”) in the southern Sierra Madre, southeastern Wyoming, is anomalous given its distance from the nearest documented plutons of

Tracking the Archean-Proterozoic suture zone in the northeastern Great Basin, Nevada and Utah

It is important to know whether major mining districts in north-central Nevada are underlain by crust of the Archean Wyoming craton, known to contain major orogenic gold deposits or, alternatively,

Early Archean to Mesoproterozoic evolution of the Wyoming Province: Archean origins to modern lithospheric architecture

Local preservation of 3.6–3.0 Ga gneisses and widespread isotopic evidence for crust of this age incorporated into younger plutons indicates that the Wyoming Province was a 100 000 km2 middle Archean

Paleomagnetism of the Middle Proterozoic Laramie anorthosite complex and Sherman Granite, southern Laramie Range, Wyoming and Colorado

We present the results of a combined paleomagnetic and 40Ar/39Ar geochronologic investigation of the Middle Proterozoic Laramie anorthosite complex and Sherman Granite in the southern Laramie Range

Laramie Peak shear system, central Laramie Mountains, Wyoming, USA: regeneration of the Archean Wyoming province during Palaeoproterozoic accretion

Abstract The Laramie Peak shear system (LPSS) is a 10 km-thick zone of heterogeneous general shear (non-coaxial) that records significant tectonic regeneration of middle-lower crustal rocks of the

The Proterozoic Cheyenne belt marks the southern boundary of the Archean Wyoming province. Within the Medicine Bow Mountains, it consists of strongly deformed, lithologically distinct blocks bounded
