| 英文摘要 | Detrital thermochronology data is widely used in revealing the tectono-thermal evolution of drainage basins in orogen belts. Due to the impact of many factors, such as drainage topographic features, the spatial distribution of erosion, the age-elevation relationship and so on, multiple solutions exist for the significance of detrital thermochronology data. Among. such factors, the assumption of uniform spatial erosion maybe not rigorous. An inversion model was suggested to compute the tectono-thermal evolution of drainage basins using landform data and observed detrital thermochronology data. In this model, the distribution of altitudes is calculated using DEM data of drainage basins; slope angles are used to quantify spatial erosion rates for different altitudes; then different elevations' relative sand contribution ratios to detrital sample are determined. The detrital ages was acquired through apatite-fission-track (AFT) analysis. A variety of possible age-elevation relationships are randomly set, and the density distribution curve of detrital ages is calculated according to the settled relationships. Through the Chi-square test of observed and calculated age density distribution curve, the most probable age-elevation relationship is chosen which represents actual tectono-thermal evolution of drainage basin. |
