英文摘要	The eastern taerbieke gold deposit is geographically located to the south of the axi gold deposit in the 'fulaski basin, western tianshan, and tectonically occurs in the western section of the early paleozoic borohoro island are between the junggar plate to the north and the yili-central tianshan micro-plate to the south. the eastern taerbieke andesites are geochemcially similar to high-mg andesite, e. g. high sio(2)(58.94% similar to 63.85%) and mgo contents (3.75%similar to 6.59%), mg values(58 similar to 69), and 0 (94, 2 x 10(-6) similar to 241 x 10(-6) and ni (54.5 x 10(-6) similar to 126 x 10(-6)) contents, and low feo(t)/mgo ratios. except for slight low sr contents ( 235 x 10(-6)similar to 696 x 10(-6)), they are also geochemically similar to adakites, e. g., high al(2)o(3) (15. 39% similar to 16.65%), high sr/y(23.8 similar to 48.1) ratios, no significant eu anomalies and clear depletion in nb, ta and ti. la-icp-ms u-pb age data suggest that [lie eastern taerbieke andesites were generated in the early carboniferous (347.2 +/- 1.6ma). the enrichment in large ion lithophile elements (e.g. rb, th and u) and depletion in high field strength elements ( e. g. nb, ta and ti), and higher light rare earth element contents relative to heavy rare earth elements for the andesites, suggest that they are similar to island are rocks. we suggest that the eastern taerbieke andesites were possibly generated by the interaction between mantle. and melts derived by partial inching of subducting sediments and altered oceanic crust during the subduction of late paleozoic northern tianshan ocean. the interaction between mantle and melts possibly played an important role in generating an mineralization.
