- •
We studied the lithosphere control on the origin of K-rich intraplate mafic lavas in Songliao basin, NE China.
- •
Olivine major and trace element data confirm the SCLM source for EM1-like geochemical signature of studied mafic lavas.
- •
We constrained the lithology, metasomatism and the role of mixing of different mantle components in the source region.
