Mylonite developed a dextral strike-slip fault of the 4 km wide Brookneal shear zone in the southwest Virginia Piedmont. The shear zone is, in part, superimposed on the Melrose Granite where an SC mylonite (this sample) was produced by dynamic recrystallization of all constituent minerals. The age of movement on the Brookneal shear zone has been constrained by isotopic dating to between 324 and 300 Ma.
