We have investigated petrogenic characteristics of detrital opaque Fe-Ti oxide minerals (DOPQ) in sand samples collected from Holocene streams draining exclusively igneous and metamorphic source rocks in the Rocky Mountain region under a semi-arid climate, and from the Appalachian Mountains under a humid climate. Whereas no single character of DOPQ may be diagnostic of provenance, discriminant function analysis of the complete set of data shows that collectively they are diagnostic in 95% to 100% of cases. -from Authors

Abstract
We have investigated petrogenic characteristics of detrital opaque Fe-Ti oxide minerals (DOPQ) in sand samples collected from Holocene streams draining exclusively igneous and metamorphic source rocks in the Rocky Mountain region under a semi-arid climate, and from the Appalachian Mountains under a humid climate. Whereas no single character of DOPQ may be diagnostic of provenance, discriminant function analysis of the complete set of data shows that collectively they are diagnostic in 95% to 100% of cases. -from Authors
