| 英文摘要 | Cenozoic basalts from the Linqu County, Shandong Province, China entrain some clinopyroxene crystals, of which many contain abundant glass melt inclusions. These melt inclusions are extremely irregular in shape with most grain sizes in a range of 10-50 mu m and coexist with low-Mg(#) olivines, labradorites and Ca-rich potassium feldspars. In-situ major and trace element analyses show that the glass melt inclusions are high in alkalis (Na(2)O+K(2)O > 10 wt%), SiO(2) (> 54 wt%), CaO and FeO (> 4 wt%), but low in MgO (Mg(#) < 20), and have LREE enrichments ((CeNb)(cn) = 11.6-16.4) and apparently positive Eu anomalies (Eu/Eu* > 2), thus having phonolitic compositions. The compositional features of clinopyroxene crystals, glass melt inclusions and their coexistent minerals suggest that these melt inclusions were exotic melts in clinopyroxenes trapped prior to their entrainment in the host basalt. The discovery of these melt inclusions provides a new approach to further investigating the evolution of Mesozoic lithospheric mantle beneath the southeastern North China Craton. |
