DIRECT DETERMINATION OF STRONTIUM ENRICHMENT ON GRAIN-BOUNDARIES IN A GARNET LHERZOLITE XENOLITH BY PROTON MICROPROBE ANALYSIS

Abstract:

The mechanisms by which trace and radiogenic elements are held and transported in the Earth's mantle are of prime importance in studies of basalt petrogenesis and the chemical processing of the mantle. While such mechanics include the migration of melts and the convective physical admixture of differentiated material1, the role of fluids as transport agents has attracted much interest, especially, in regions affected by kimberlitic activity2-4, continental basaltic volcanism5,6, and in areas ...
