- W2390415906 abstract "The tectonics of Shandong Province is divided into two parts by a long-lived wrench fault zone—Tancheng-Lujiang Fault. The eastern part is named Jiaodong and the western part is called Luxi. Mesozoic mafic dikes are widely distributed in Luxi (Mengyin and Zichuan) and Jiaodong regions of Shandong Province, China, providing an opportunity of investigating the nature of Mesozoic lithospheric mantle beneath the North China Craton (NCC). This paper presents major and trace elements for some newly reported mafic dikes from Shangdong to decipher the geochemistry and petrogenesis of these mafic dikes. The major elements were analyzed by wet chemical analysis at the Institute of Geochemistry, Chinese Academy of Sciences (IGCAS). Analytical uncertainties are from ±1%to 3%for major elements. The rare earth elements and other trace elements were analyzed by ICP-MS at the Isotope Analysis Center of IGCAS. The analytical accuracy is better than 5%for REE, and 10%for other trace elements. The mafic dikes from the Jiaodong region are mainly lamprophyres (spessartites) and gabbros, and the dikes from the Luxi region are gabbros and diabases. The SiO2 contents of the dikes range from 48.63%to 56.02%. Based on the evidence from major and trace elements, the mafic dikes are characterized by enrichment in LREE and LILE (such as Ba, Sr, Pb and K), and depletion in HREE and HFSE (such as Nb, Ti and P). The dikes were derived from partial melting of metasomatized portions of the subcontinental lithospheric mantle (EMⅠ), followed by fractionation of olivine, clinopyroxenes, plagioclase and Ti-Fe oxide. The mafic dikes are characterized by high Rb/Sr and Nb/Ta and normal Zr/Hf ratios, which indicate an early-stage rutile-rich and phlogopite-rich metasomatism and few carbonatite-rich metasomatism affected the source rocks for the mafic dikes. Moreover, in the sources, there exists evident crustal contamination due to the subduction of Yangtze lower crust." @default.
