  2. The pges abundance patterns of residual mantle rock with a peleo - subduction background is characterized by pd, pt depletion and ir, ru relatively enrichment, while the basalt and basic dyke by the processing of partial melt in the same background take an opposite feature of pd, pt enrichment and ir, ru depletion. the existence of fluid in the subduction zone increases the degree of partial melt on the one hand, and on the other, activates the activity of pd, pt compare to ir, ru, and thus reduces the pd ir and pt ru in residual mantle rock. the pges patterns for basalt and basic dyke from two carboniferous volcano zones to south qoltag and north turpan - hami basin, xinjing uigur autonomous region, take a shape of gentle positive inclined curve with lower pt and pd differentiation and lower pges. all these features are obviously different from that of basic dyke and basalt from typical ophiolite and therefore the author believe that their fluid - rich paleo - subduction zone environment can be ruled out
