Cenozoic basalts in Shandong province are mainly distributed along and east to Tanlu Fault Zone, with minor in West Shandong. This study reported major and trace element compositions of bulk rocks, in situ Pb isotope compositions of melt inclusions and their host olivine chemistry in Zhoucun basalts, Western Shandong to constrain their petrogenesis. The results show that the Zhoucun basalts are weakly alkali basalts, with high SiO_2 and Al_2O_3, low total alkali contents, CaO/Al_2O_3 and Fe_2O_3~T in major ...
