There was a construction site Joe and I checked out on Wake Forest Rd.  There was interesting pegmatite veins running through mostly saprolitic gneiss.

This is a good reference for when people ask what to look for when prospecting.  That is, a feature that cross-cuts the dominant structure -- the diagonal pegmatite band across the horizontal saprolite layers, in this case.  It does not have to be of the same scale or as obvious or dramatic, but this is one thing to look for.  When scraping a creek bank with a shovel, it might not be as obvious as this machine cut.  Even without digging or scraping, sometimes you can "connect the dots" of like features and make a good guess on the direction of a cross-cutting vein.
