Abstract: Songpan-Ganzi folded belt in Sichuan province of China is a major issue to geoscientists. In recent years, petroleum geologists pay more attention to it because of the discovery of a low velocity-high conductive layer in the deep of this folded belt by seismic depth sounding and gravity-magnetic-electric survey. The research of large igneous rock province-Ermei basalt extrusion-mantle plume shows that Songpan-Ganzi folded belt is a hopeful target for breakthrough of petroleum exploration, and the key issue is how to make well a coupling and optimization among its faults, structures, traps and reservoirs.

Key words: Sichuan, Ganzi, mantle, low velocity, petroleum exploration
