DONG Gui-yu, CHEN Hong-de, HE You-bin, QING Zhi-yong,LUO Jin-xiong, et al. Some Problems on the Study of the Mixed Siliciclastic Carbonate Sediments[J]. Advances in Earth Science, 2007, 22(9): 931-939.

The study of Mixing deposit has theoretical significance and practical value. On the basis of the previous studies and combination with some concrete examples, the definition of Mixing deposit is revised and supplied, the Hunji Rock and the Hunji stratum of two ends are classified and named. Based on the factors such as definition, cause of formation, component, structure , deposition structure and contacting relation, and according to the sediment event+section structure of Mixing deposit, mixed sedimentary type can be divided into three categories: the blended mixing deposit, the salutatory mixing deposit. and the complex mixing deposit and Carried out summarization and induction to the prehominid studies; discussing the governing factor of mixing deposit; Commenting the relation between deposition sequence stratigraphy and the mixing deposit under two kinds of advantage sedimentary background of the mixed siliciclasticcarbonate; discussing the relation between the mixing deposit and Oil gas,according to itself characteristic and aiming at the research current situation of the mixing deposit, pointing out some problems and the future research direction in the last.
