Formation Mechanism of Mud Volcanoes/Mud Diapirs Based on Physical Simulation

Figure 4

Experiment 1-1 records the formation simulation of mud diapir under overpressure. (a) After fluid injection, the model surface forms a mound like uplift; (b) the side view of the model; (c) the crosscutting diagram of the model outer edge, which shows that under the action of fluid arching, the stratum appears to be upward bending; (d) the crosscutting diagram of the model center, which shows that the stratum is faulted and pulled upward under the action of diapir.
