Abstract:
The physical modeling, which developed rapidly and applied widely, has been widely accepted as an effective method to study the deformation mechanism and the process of tectonic evolution. Granular materials, which were widely used in the physics modeling, were commonly used to analog the deformation of the upper crust. Some attribute of different materials play an important role in the physical modeling. Many previous studies suggested that the granule roundness determined the angle of internal friction. The detail of their impact, however, is still obscure and poorly understood. Microspheres, beach quartz sand, and artificial quartz sand are used to investigate the impact of the roundness on physical modeling in this case study, using three models with some similar parameters. The present study shows that the microsphere with perfect roundness made it easy to roll, leading to the profile of fold-thrust belt round. Some deformation details are difficult to decode, and the strain distribution was dispersed. The model with artificial quartz sand uplifted highest, due to the angular roundness and the granule are difficult to move. The strain was most concentrated, suggesting significant discrepancy of strain value among different part of the deformation area. Beach quartz sand with appropriate roundness, however, showed the medium performance what we expect in structure physics modeling.
