| Abstract: | The volcanic rocks of Tamulangou Formation in southern Manchuria are composed mainly of olivine basalt,pyroxene basalt and basaltic andesite.LA-ICP-MS zircon U-Pb dating results show that the volcanic rocks formed at the end of Middle Jurassic,ranged from 164 Ma to 161 Ma.Geochemical data show that the volcanic rocks belong to high-K calc-alkaline series,have low contents of MgO(1.64%-9.59%) and small Mg#(0.26-0.66);The chondrite-normalized rare earth element(REE) patterns indicate that the volcanic rocks a... |
