The Llano Uplift of central Texas records middle Proterozoic               tectonism and metamorphism that has not been overprinted by                     subsequent events, unlike other Grenville-aged provinces in Canada              and the Appalachians.  This project will concentrate on U-Pb                    geochronometry integrated with field, petrographic, and analytical              data constraining the timing of sequential deformational, meta-                 morphic and intrusive events will test several current hypotheses               of the tectonic setting of the Precambrian margin of North                      America.  Results of this study of the Llano Uplift are expected                to be applicable to understanding the evolution of the Grenville                orogen along the entire margin.
