摘要
The differences of thermal conduction and its temperature-varying track of the heat source body at various structural environments have been studied. Hypothetically, geologic heat source body is cut successively into several segregative bodies with a fixed cubage. With the segmented number increasing, the conductive surface area of heat source body begins to get larger, which separately is similar to the heat geologic body in different tectonic zones that has a various enclosed coefficient η（η=S<sub>0</sub>/sum from i=（1,n）（S<sub>i</sub>））. Finite-element simulation result shows that the thermal conduction speed of spreading from the heat source body to its wall rock is slow→higher→highest, when heat source bodies are situated respectively at compressive, shear and tensile deformation zones, corresponding rates of their temperature drop are low→higher→highest. Research indicates that the temperature’s dropping rate of heat source body has an inverse relationship with enclosed coefficient η for different structural
The differences of thermal conduction and its temperature-varying track of the heat source body at various structural environments have been studied. Hypothetically, geologic heat source body is cut successively into several segregative bodies with a fixed cubage. With the segmented number increasing, the conductive surface area of heat source body begins to get larger, which separately is similar to the heat geologic body in different tectonic zones that has a various enclosed coefficient . Finite-element simulation result shows that the thermal conduction speed of spreading from the heat source body to its wall rock is slow→ higher→ highest, when heat source bodies are situated respectively at compressive, shear and tensile deformation zones, corresponding rates of their temperature drop are low→ higher→ highest. Research indicates that the temperature’ s dropping rate of heat source body has an inverse relationship with enclosed coefficient η for different structural zones. This result can explain the tectono-physicochemical reason of magmatite evolution and its difference.
