THE LITHOFACIES AND GENETIC TYPES OF ALLUVIAL FANS IN CONTINENTAL RED BASINS—A CASE STUDY OF THE SANDU RED BASIN IN NORTHWESTERN JIANGXI

摘要: 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。
Abstract: On the basis of the properties,textures and primary structure of deposits,21 sedimentary microfacies types are distinguished in the alluvial fan of the Sandu red basin.According to the spatial associations and genetic relations of different microfacies,the deposits in the basin may be classified into seven genetic types.Of the deposits the channel deposits are subdivided into main channel deposits and distributary channel deposits for the first time.
