The variety of thermal conduction resulting from segmented degree of heat source body and its bearing on temperature change

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 increasin g, the conductive surface area of heat source body begins to get larger, wh ich separately is similar to the heat geologic body in different tectonic z ones that has a various enclosed coefficient eta(eta = S-0/Sigma(l = 1, n) S-i) . Finite-element simulation result shows that the thermal conduction s peed of spreading from the heat source body to its wall rock is slow--> hig her-highest, when heat source bodies are situated respectively at compressi ve, shear and tensile deformation zones, corresponding rates of their tempe rature drop are low--> higher--> highest. Research indicates that the temperature's dropping rate of heat source body has an inverse relationship with enclosed coefficient eta for different st ructural zones. This result can explain the tectono-physicochemical reason of magmatite evolution and its. difference.
