根据沉积物的性质、结构及原生沉积构造，将三都红盆冲积扇体划分为２１种沉积微相类型。据不同微相空间组合及成因联系将盆内沉积物划分为７种成因类型，其中首次将河道沉积又细分为主河道沉积和分支河道沉积。
According to the nature, structure and primary sedimentary structure of the sediments, the Santong red basin alluvial fan bodies are divided into 21 types of sedimentary microfacies. According to the spatial assemblages and genesis associations of different microfacies, the sediments in the basin are divided into seven genetic types, of which the river sediments are subdivided into main channel sediments and branch channel sediments for the first time.
