Analysis of Heavy Mineral Combination Characteristics and Sedimentary System of 3rd and 4th Member of Quantou Formation in Daqing Placanticline and Its East
Through investigation of the heavy mineral combination characteristics and ZTR maturity index feature of 3rd and 4th member of Quantou Formation in Lower Cretaceous in Daqing Placanticline and its east, sedimentary sources and sedimentary systems have been studied systemically in this paper. Study shows that six sedimentary systems exist in this region, they are north, Baiquan-Mingshui, west Yingtai, southwest Baokang, south Huaide and east sedimentation system, the influence area and intensity changes of each sedimentation system have been analyzed synthetically and determined.
