Sedimentary system of Tendi Formation to AG Formation in the western slope of X block, Muglad Basin
Online published: 2014-06-06
Based on the paleontology, cores, logs and seismic data, this paper analyzed the types and evolution of sedimentary systems from Tendi Formation in Tertiary to AG Formation in Cretaceous in the western slope of X block in Muglad Basin. The result shows that influenced by the source of the south part of western Matelige uplift, the study area is with rift lake basin sedimentary characteristics in Early Cretaceous, Late Cretaceous, and Eocene; the distribution from delta facies to shallow lake facies extends from west to east; in addition, （semi-） deep lake facies develops in the eastern part of the study area in the early stage of Early Cretaceous. The depression lacustrine deposition is manifested in the late period of Early Cretaceous, Paleocene and Oligocene-Pliocene. The fluvial facies promote to the west of the study area and comes into being delta, and a small range of shallow lake occurs in the east of the study area. In conclusion, the regional tectonic activities significantly control the sedimentary filling in the western slope of X block in Muglad Basin, and the sedimentary evolution shows obvious regularity.
