Correspondence analysis, a method of principle components analysis is applied to structural data collected from the Stansbury Mountains, located in Tooele County, Utah to aid in investigating the nature of folding and faulting in the region. The Stansbury Mountains of north-central Utah lie along the western edge of the Sevier orogenic belt, in the eastern Basin and Range physiographic province. The dominant structural feature of the area is the north-trending, east-vergent Deseret anticline which is interpreted as a tight, steeply overturned fold. Along its overturned eastern forelimb, the Deseret anticline is juxtaposed against the east-vergent, Martin Fork syncline to the east, by the Broad Canyon, thrust. Results from the correspondence analysis suggest that deformation in the upper and lower plates of the Broad Canyon thrust are very similar. This may be due to the occurrence of the shared overturned forelimb of the Deseret anticline/Martin Fork syncline fold pair within the upper and lower plates of the Broad Canyon thrust.
