Differential partial melting process for temporal variations of Shandong basalts revealed by melt inclusions and their host olivines

The link between the geochemical variability of lavas and their source lithologies is very important in understanding the nature of mantle sources and melting processes. The Cenozoic basalts of Shandong province are ideal targets for addressing this issue. Previous studies have revealed two different types of basalts in Shandong province. The first type includes older, slightly alkalic basalts (SAB) with EMI oceanic island basalt (OIB)-like...
