英文摘要 | Based on empirical formula of heat conductivity, heat capacity and coefficient of thermal expansion varied with temperature, we adopt implicit finite difference method to calculate non-linear heat conduction equation and determine plate thickness and basal temperature of oceanic lithosphere using sea-floor ages and bathymetries of the North Pacific Ocean and the North Atlantic Ocean. The results indicate that the thickness of oceanic lithosphere is about 105 km and the basal temperature is about 1450 degrees C, which accord with the results obtained by Stein et al. When the varied-parameters plate model is applied to explore the formation mechanism of sedimentary basin due to lithospheric stretching, it can be found that the predicted subsidence derived from the varied-parameter model is greater than that derived from the original uniform stretching model. Therefore we point out that the reason for McKenzie's uniform stretching model to predict larger initial subsidence and smaller thermal subsidence than observed results is possibly because this model didn't take the dependence of lithospheric thermal parameters on depth or temperature into account. |
