| Abstract: | Jiumiao basic complex exposed in western Liaoning is composed of three stages of intrusive rocks,i.e.webasterite,noritic gabbro and bojite.Based on geological,petrographical,geochemical and isotopic data,it had been verified that these rocks were derived by partial melting from enriched upper mantle . The basic complex was formed through fractional crystalization.The magma event represents the North China Plate splitting at its margin during Sibao movement and starts oceanic crust evolution stage. |
