| Abstract: | The article studies the coincident relation between the depositional characteristics & depositional environmental changes of Yanchang Formation in Ordos Basin and the Qinling Orogenic Movement in Indo-Chinese epoch. The researches are based on the area ancestral structural movement regularities, depositional geological setting, depositional features and the evolutional regularities of sedimentary context sequence in early Triassic Yanchang Formation. At the same time,it analyses the Qinling Orogenic Movement in Indo-Chinese epoch, which plays the controlling role in the basin boundary nature,the sedimentary derivation, fragmental materials transportation & depositional mechanism effects, depositional system types and depositional context belt distribution regularities of Yanchang Formation in Weibei area in the south of Ordos Basin. |
