- Аннотация: The objective of end-member modeling is to provide the simplest possible explanation of compositional variations in cases where the observed variations is believed to be the result of physical mixing but a priori knowledge of mixing processes is absent. The inverse end-member modeling algorithm of Weltje (1994, 1999) was tested on major element data to evaluate its usefulness for unraveling element paragenetic associations in channel sediments of a heterolithic river basin. The Guadalhorce basin located in the south of the Iberian Peninsula was chosen for this experiment. The end-member modeling proved to be a powerful tool for structural analysis of multi-sourced geochemical fluxes. The results of modeling made it possible to explain variation among major element compositions of sediments in terms of mixing of 4 end members. The relative abundances of the EMs were used for describing spatial changes in sediment geochemistry as well as for sediment classification and mapping.
