Sand box model, stretching deformation physical simulation method and system and application

Abstract

The invention belongs to the technical field of lithosphere stretching deformation simulation, and discloses a sand box model, a stretching deformation physical simulation method and system and application. A first layer (bottommost layer) of the sand box model is a simulation material layer of mantle on a lithosphere, a second layer is a simulation material of tough earth crust, and a third layer is a brittle earth crust simulation material. The first layer is silicone, the second layer is wet clay, and the third layer is quartz sand. The simulation material of the mantle on the lithosphere can also be honey, paraffin or plasticized rosin and the like; the simulation material of the tough earth crust can also be plasticine, kaolin and the like; the brittle earth crust simulation material can also be clay, gypsum or talcum powder and the like. According to the invention, the limitation that the existing physical simulation experiment method can only simulate the stretching brittle deformation of the superficial layer of the earth crust is made up, so that the structure physical simulation experiment can simulate the deformation characteristics of the whole lithosphere stretching structure.

Description

technical field [0001] The invention belongs to the technical field of lithosphere extension deformation simulation, and in particular relates to a sand box model, a physical simulation method for extension deformation, a system and an application. Background technique [0002] At present: Structural simulation experiment is a physical experiment method to study and simulate the deformation characteristics, genetic mechanism and dynamic process of natural geological structure phenomena, also known as structural physical simulation experiment. Structural physics simulation experiment is to reproduce the formation and evolution process of a certain structure under laboratory conditions and according to the actual geological conditions or background, and to demonstrate the relationship between deformation characteristics and physical parameters in the system where the experiment and the actual geological body are similar to each other. The control function or effect of the stru...

Problems solved by technology

When setting up a brittle-ductile double-layer sand box, the lower ductile layer is followed by the upper brittle layer, and the material properties of the two layers change greatly. The lithospheric mantle is missing below, and the layered structure of the lithosphere cannot be well restored, so the extension of the lithosphere will be limited. The final effect and reliability of the deformation experiment
