- The team ' s measurement of thorium revealed the overall abundance pattern of heavy elements for this object
該隊(duì)的測(cè)量發(fā)現(xiàn)釷的總體格局豐富的重元素,為這個(gè)目的 - 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余地幔巖的pges配分以pd , pt明顯虧損和ir , ru相對(duì)富集為特征，而部分熔融產(chǎn)物的玄武巖和基性巖脈則呈現(xiàn)相反的ir , ru明顯虧損和pd , pt相對(duì)富集特征。俯沖帶中流體的參與一方面增加了部分熔融程度，有利于pd , pt從原始地幔進(jìn)入熔融相另一方面，流體的作用使得pd , pt相對(duì)于ir , ru遷移活動(dòng)性效率提高，造成地幔巖中 - Thus the cumulative consequence of galactic chemical evolution starting from low metallicity agb stars , namely , the average abundance patterns of sbh part with 140a204 ( or the snl component part with 92a132 ) in different metal conditions , should be similar ( ornearly similar ) to the corresponding solar s - bajn component
低金屬豐度條件下，由于中子輻照量隨金屬豐度的降低而升高， s _ ( ml )產(chǎn)量低于s _ ( mh ) 。雖然s _ ( ml )分布與太陽(yáng)系有差異，但對(duì)于質(zhì)量范圍92 a 132 ，任何金屬豐度下分布與太陽(yáng)系大體相似。
