  4. 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

Directions are obtained by two means : calculation and measure. our investigations are summed as follows : 1 the lpo relations between olivine and orthopyroxene are different from usually situations : 100ol 001opx, 010ol 100opx, 001ol 010opx ; 2 the seismic anisotropy of the ultramafic rocks in damaping is obvious. their characters are consistent with the structures of the rocks and fabrics of minerals, which means seismic anisotropy is mainly controlled by rocks fabrics ; 3 seismic velocities suggest that the composition of upper mantle in damaping region is resemble to the xenoliths, which major component is lherzolite

  9. It shows that the resolution of the crust interface ' s shape on this four profiles is very good, nevertheless that of the velocity structure is relatively poor. the crust and upper mantle ' s fine configuration on the hq - 13 profile is obtained by our tomography, which reveals some important structure and dynamic features of this region : the velocity structure of the crust consists of three layers, the upper crust, the middle crust and the lower crust. however it also can be divided into six lateral blocks, each of them " s velocity is always higher or lower than that of its neighboring blocks

  10. Beginning with the minerogenetic theory of mantle plume, the basic geological conditions of this type deposit can be summarized through studying typical copper - nickel sulfide deposits which have close bearing on continental flood basalt. in contrast with high - mg volcanic magmatic activity, it can be found that some intrusive rock bodies have ni - minerogenetic geology condiction. xilaping rocks in binchuan - chenghai region has some basic geological condiction and reflects some extent minerogenetic. all these testify this region has very larger potentiality of finding copper - nickel sulfide deposits
