- •
Comprehensive geophysical experiments were operated in Emeishan LIP, SW China.
- •
Distinct features on the crustal nature and geometry of the Inner Zone were manifested.
- •
A 15–20 km-thick mafic layer is detected at the base of the crust in the Inner Zone.
- •
This mafic layer reflects the vertical crustal growth through magmatic underplating.
- •
This study provides evidence for and characterizes a plume-modified crust in a LIP.
