- •
Heterogeneities of four Longmaxi Formation shale samples were evaluated by representative elementary area.
- •
Nanoporosity is confirmed by the QEMSCAN, FIB-SEM, and Nano-CT methods.
- •
Organic matter with abundant nano-pores contributes about 5%–33% of total nanoporosity.
- •
Nanoporosity is mainly provided by the pores smaller than 400 nm.
