Re-evaluate the conventional reciprocal sedimentation model for icehouse mixed carbonate and siliciclastic systems using high-resolution subsurface imaging.
Integrated 3D seismic reflection data with wireline-log crossplot analyses across the Cisco Group.
Mapped lithology distribution using model-based post-stack inversion, probabilistic neural networks, and supervised Bayesian classification.
In ~400 kyr sequences, relative sea-level fall begins with slope carbonate accumulation, followed by siliciclastic offlapping fans at the slope toe and transgressive mixed facies.
In ~1200 kyr composite sequences, declining siliciclastic input during sea-level fall results in truncated topsets with carbonate- and mixed-facies foresets.
Transgressive carbonates frequently form shelf-edge buildups that restrict subsequent highstand siliciclastic transport toward the slope.
