英文摘要	Ar-40/ar-39 geochronology, major and trace elements and sr-nd isotope data are presented for the early tertiary basaltic rocks from the jianghan basin. the volcanic rock were was erupted at ca. 57ma and belong to subalkali series. these basaltic rocks are generally characterized by enrichment in lile and lree ((la/yb) cn = 3. 5 similar to 10.4) with insignificantly negative eu anomalies (eu/eu-center dot = 0.99 similar to 1.08). these rocks display insignificant nb-ta positive anomalies, similar to those of ocean island basalt (oib). their elemental and sr-nd isotopic signatures are similar to those of early tertiary volcanic rocks from the southern margin of the north china block and the late cenozoic basaltic rocks in southeast china. combined with pb data of mesozoic basalts from the middle-lower section of the yangtze river, we propose that the geochemical characteristicsfeature of the cenozoic lihtospheric mantle beneath the northern yangtze block might inherit from that of mesozoic lithospheric mantle. these basaltic rocks from the jianghan basin in the northern yangtze block were generated from partial melting of emii-like lithospheric mantle in respondings to the tectonic regime of intracontinental extension regime.
