Calculation method and device for denudation rate of provenance area in sedimentary basin

Abstract

The present invention provides a method and device for calculating the denudation rate of the source area of ​​a sedimentary basin. The planar position of the source area, transport area and converging area; the plane area and the number of sedimentary bodies in the converging area can be obtained by statistics; the average thickness of the sedimentary body in the converging area can be obtained by statistics; The cross-sectional area of ​​the channel and the extension length of the transport channel; determine the denudation area area of ​​the provenance area and the denudation duration of the target interval; calculate the denudation rate of the provenance area of ​​the sedimentary basin. This method realizes the accurate calculation of the denudation rate of the source area of ​​the sediment, quantitatively characterizes the denudation rate of the source area of ​​the sedimentary basin, and is conducive to improving the accuracy of the restoration of paleogeomorphology and paleoclimatic conditions during the sedimentary period of the target interval.

Description

technical field [0001] The invention relates to the technical field of geological research, in particular to a method and device for calculating the erosion rate of a provenance area of ​​a sedimentary basin. Background technique [0002] For a long time, scholars at home and abroad have focused on qualitative analysis of the denudation rate in the provenance area of ​​sedimentary basins. Problems such as restoration and inability to reproduce have been limited to qualitative descriptions, and have not been able to achieve quantitative characterization of the erosion rate of sediment source regions. The inability to quantitatively characterize the erosion rate of the sediment source area will affect the accuracy of the restoration of paleogeomorphology and paleoclimatic conditions during the depositional period of the study target interval. SUMMARY OF THE INVENTION [0003] An embodiment of the present invention provides a method for calculating the erosion rate of the pr...

[0002] For a long time, scholars at home and abroad have focused on qualitative analysis on the erosion rate of provenance areas in sedimentary basins. Problems such as restoration and irreproducibility have been limited to qualitative descriptions, and have not been able to achieve quantitative characterization of the denudation rate of sediment source regions.

Unable to quantitatively characterize the denudation rate of the sediment source area, which will affect the accuracy of paleogeomorphological restoration and paleoclimatic condition restoration during the sedimentary period of the research target layer
