- •
The Maokou karst was an inland facies-controlled eogenetic karst.
- •
Grainstone exhibits eogenetic karst features with high porosity and permeability.
- •
The coarse-grained limestones acted as inception horizons, which were more favourable to karstification than the micrites.
- •
High-quality karst reservoir developed in karst highland and karst transitional zones.
