Preli minarystudies have been carried out on the PGE geochemis-try of the basalts in the Emeishan area ( QingyingPower Station profile) and Xinjie area (Zhang andLi ,1998) ,andinthe Shuicheng and Weining areasinGuizhou (Li et al .,2003) .

| Abstract: | To disclose and study the magma genesis of the Permian basalts in the Jinping (金平)area, the PGE and Au contents of the Permian basalts in the Jinping area were assayed by use of the ICP-MS method. The PGE data show relatively strong differentiation of basaltic magma in comparison with the primitive mantle. The primitive mantle-normalized pattern is a left-dipping curve of the Pd-Pt enriched type. The Pd/Ir ratios of the PGE of the Permian basalts in the Jinping area are higher than those of the primitive mantle and the upper primitive mantle and the chondrite meteorite. The Pd/Ir ramaterial source. It is concluded that they are derived from the basaltic magma of the upper mantle source with a lower melting degree, which shares the similar magma material source with the Emeishan Permian basalts as a whole. |
