Embodiment 1
[0068] Predicting the distribution range of sedimentary facies belts in the piedmont area of Bogda Mountain includes the following steps:
[0069] (1) According to the outcrop profiles in this area, the sedimentary facies types of different horizons in each profile are identified by using sedimentary facies markers. Alluvial fan facies, fan delta facies, braided river delta facies, and meandering river deltas are developed in this area There are seven types of sedimentary facies, including facies, fluvial facies, shore-shallow lacustrine subfacies, and turbidite fans. Such as image 3 As shown in , select several measuring points for each type of sedimentary facies, and measure the distance L from each measuring point to the provenance area.
[0070] Taking the fan delta facies as an example, a total of 11 survey points were selected and named respectively as survey point 1, survey point 2 ... survey point 11, and the distance to each survey point was measured by using the ...
