| 英文摘要 | The permian mafic dikes in the nw tarim basin provide important constrains on the late-paleozoic tectonic evolution of the tarim basin and its adjacent area. the mafic dikes in the bachu area are mainly diabases and exhibit enrichment in lile, lree and hfse. these samples exhibit 0. 84 similar to 1. 23 of la/nb, 5. 80 similar to 7. 81 of zr/nb, 2. 6 similar to 15. 4 of ce/pb and 27. 0 similar to 37. 3 of nb/u. the initial (87) sr/(86) sr ratios range from 0. 70495 to 0. 70560 and epsilon(nd) (t) values are from - 1. 7 to + 2. 0, different from those of the subduction-related magmatism and the oceanic island basalts ( oib). such geochemical features suggest that these samples might be product of the low degree partial melting of the garnet-bearing peridotite. these samples are derived from the interaction of the asthenosphere with lithosphere in response to uplifting asthenosphere in the extensional setting. taking account into available data, an irregular variation for mantle source is shown from the tarim interior to the southwestern tianshan belt. |
