On first on disk 3 and second disk 6 exist between the interface of the simulation tomography of simulated substrate horst respectively it is certain
When amount of tension, the simulation cap rock meeting recurring structure on the upside of simulation detachment layers changes, disconnected in the simulation of the simulated substrate horst
The interface of layer forms new simulating boundary tomography, can form graben formula structure.
(3), the thickness based on the simulation cap rock continues to be laid at least one layer of simulation cap rock on multilayer simulation cap rock,
And the simulator is stretched based on the stretching mode and the amount of tension, when back is presented in the cap rock surface of at least one layer simulation cap rock
When shape structure, the corresponding physical analogy model of default procedure parameter of the selection is obtained.
Based on the simulator stretching mode and amount of tension make the simulation detachment layers and simulate cap rock structure occur
Change, after forming graben formula structure, based on the thickness of the simulation cap rock, continues to be laid on multilayer simulation cap rock at least one layer of
