Chinle provenance

    I am trying to locate papers on determining the provenance of sediments in the Chinle Formation using mineralogy.  Most studies (like Stewart et al's USGS paper and Dubiel's studies) suggest provenance indriectly through inferred stream flow directions (these streams seem to be flowing off the early Mesozoic magmatic arc, these streams seem to be flowing off the Uncomphagre highlands), but very few provide much in the way of detailed mineralogical studies with the potential source rocks to establish a more concrete tie.  Does anyone know if such studies have been done?
