Meli:

WRI is using portable XRF to find and map sites and to characterize living 
and activity areas by their chemistry.  WRI presented on this at SHA in 
Williamsburg for characterizing living and activity areas for anomalous P, K 
and metal values for Fort Louis de Louisianne and worked on the Ravenscroft 
Site at that conference.  We gave an abstract at SAA in Austin on an 
extensive project we did for the mineral industry  for characterizing hidden 
midden areas and burials for prehistoric sites in Arizona.  WRI is going to 
be presenting at SAA on pXRF work in Mexico to confirm and complement 
traditional P  "wet chemistry" methods Mexico.  We are also going to present 
on usinging anomalous metal values in plants to find a deeply buried 16th 
Century shipwreck in California at WAC-6.    This is truly new and 
innovative technology with almost limitless applications for archaeology and 
I will be describing these in my upcoming paper in Archaeological 
Prospection.  If you can't make out workshop in San Diego, come to the one 
at SHA in Albuquerque.  If you have any other questions or need further 
information, please feel free to e-mail me or call me at WRI's Sonora, 
California Office number (209) 532-3873.
