| The Finite Element Simulation for Heat Conduction in Tectonite Belts |
| This paper sets up finite element models to simulate the processes of heat conduction of heat source geologic body toward conntry rocks,and to research the locus of variation in temperature of the heat source body. A heat source geologic body with certain volume is supposed to be divided into several isolate bodies.The conduction area of heat source body increases with increasing of amount of divided bodies.These divided isolate heat source bodies are similar to those in structural spacies under varing closing/opening extent.The calculated results of finite element models show that the velocities of heat conduction of heat soruce bodies under various conditions in compressive,shearing and extensional deformational belts are slow,faster and fastest respectively,their corresponding rates of temperature decreasing are small,bigger and biggest respectively. The research of models indicate that the locus of temperature varing of certain heat source body because of heat dissipation resulting from heat conduction is controlled by its structural space.This result provides the physicochemical reason for evolution and difference of structure and magmatic rock. |
