Description

technical field [0001] The invention relates to the technical field of particle size distribution of clastic sediments, in particular to a method, system and computer-readable storage medium for fitting and parameter calculation of the particle size distribution of clastic sediments. Background technique [0002] The particle size analysis of clastic sediments has always been a basic issue in the field of earth sciences, and it is also the most widely used data in sedimentology and geology; the particle size distribution of sediments is essentially the frequency distribution of different particle diameters, which not only reflects the The particle size itself also indirectly indicates the sediment transport mode, sedimentary hydrodynamic conditions and depositional environment, and is also the most commonly used data to infer the depositional process. The frequency, cumulative frequency and commonly used parameters (median, mean and variance) of grain size distribution are t...
