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

Figure 5

Experiment 1-2 records the formation simulation of mud diapir under overpressure. (a) After fluid injection, the model surface forms a mound shaped uplift; (b) the side section of the model shows the formation fold deformation inside the mound shaped uplift; (c) the cross section of the model outer edge shows that under the action of fluid arching, the formation appears to have an upward bending deformation; (d) the cross section of the model center shows the formation fault puncture under the action of diapir, and the formation on both sides appears to have an obvious fold deformation upward traction.
