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
古俯沖帶背景下的殘餘地幔巖的pges配分以pd ， pt明顯虧損和ir ， ru相對富集為特徵，而部分熔融產物的玄武巖和基性巖脈則呈現相反的ir ， ru明顯虧損和pd ， pt相對富集特徵。俯沖帶中流體的參與一方面增加了部分熔融程度，有利於pd ， pt從原始地幔進入熔融相另一方面，流體的作用使得pd ， pt相對于ir ， ru遷移活動性效率提高，造成地幔巖中 -
In this paper, thermal evolution history of organic matter of the source rocks and hydrocarbon generation history have been researched by tti method, hydrocarbon migration direction and migration times were probed combining with the area structure development feature ; distribution pattern of the main reservoir intervals on lateral and longitudinal have been predicted by researching on development feature and control factors of the reservoir intervals, the actions of reservoir conditions in hydrocarbon accumulation and bearing also were probed combining with pore evolution feature ; the micro - pore feature of regional cap and direct seal in carboniferous - lower triassic in this area have been determined with micro - capillary pressure curve and intrusive mercury curve ; the prospecting districts have been pointed out combining with the hydro - geologic feature, the potential reservoirs were classified according to trap types in this area, the author attempt to evaluate on the hydrocarbon - bearing condition in the str ata of carboniferous ~ lower triassic from hydrocarbon generation and migration reservoir condition, reserved condition etc, and predict the reservoir types and hydrocarbon - bearing patterns combining with the structure evolution. based on above, the author point out that the central block of chenghu - tuditang synclinorium and the southern block of dangyang synclinorium are the advantageous regions for exploration
