Principle of original horizontality, principle of superposition, principle of lateral continuity, principle of crosscutting relationship and unconformity.
Dissolution is controlled by both sedimentation and tectonization, and the converted degree on reservoirs is closely related to sedimentary facies and the distance from unconformity interfaces.
It's a residual mountain(unaka) which were a set of thrust blocks under the erosion unconformity.It's reservoir pore space is a fracture-vug-pore system of Ordovician carbonate karst.
Unconformities are places where rocks have been eroded before new ones are deposited, and the widespread Ediacaran-Cambrian unconformity has been a big obstacle to understanding the Cambrian explosion.
