| 摘 要： | 通过利用裂变径迹热史模拟来探讨山盆之间剥蚀沉积关系为定量对比山盆之间剥蚀沉积关系提供了一种可能的途径。其原理主要是通过裂变径迹热史曲线,求取造山带区域平均剥露速率,再将其与毗邻盆地沉积速率对比,进而判断山盆之间剥蚀沉积比例关系。通过计算可以得到大别造山带65~25 Ma区域体积平均剥露速率为1189.67 km3/Ma(当古地温梯度为25℃/km时)、1487.08 km3/Ma(当古地温梯度为20℃/km时)。其剥蚀速率至少占到了毗邻盆地古近纪平均总沉积速率的一半以上。其原理主要是通过裂变径迹热史曲线,求取造山带区域平均剥露速率,再将其与毗邻盆地沉积速率对比,进而判断山盆之间剥蚀沉积比例关系。

| Abstract: | Thermal history modelling of fission track opens a promising passage for the quantitative study of the relationship between the orogenic belt erosion and the sedimentary basin deposition.The working principle is to get the average exhumation rates of the orogenic belt through the thermal history modelling of fission track,then compare the exhumation rates with the average deposition rates of the adjacent basins to estimate the proportional relationship between the orogenic belt erosion and the sedimentary b... |
