Many of the precambrian shields or cratons are transgressed                by "mobile belts" that have been the loci of deformation and                    metamorphism subsequent to craton formation.  These belts are                   generally consistent with an origin by plate collision at former                plate margins, however, the style and relative displacements                    associated with these collisions are not well constrained.  This                renewal will continue a paleomagnetic and Ar/Ar age dating program              from rock units on opposite sides of the Brasilian mobile belt.                 Results, combined with existing data from the extension of the                  Brazilian belt in west Africa, the Pharusian belt, will allow                   assessment of the displacement and timing associated with a                     possible late Proterozoic continental collision.
