Fig. 7From: Development characteristics and controlling factor analysis of the Neogene Minghuazhen Formation shallow water delta in Huanghekou area, Bohai offshore basina Root mean square amplitude of PSS10 of BZ34 area in plain view and b Interpretation of sandbodies and sedimentary microfacies. Interpretation and calculation methods of amplitude are from Liu et al. 2018. Interpretation of sandbodies indicates that 4 sets of sandbody complexes developed in the PSS10 depositional phase belonging to external front of a delta and shore-shallow lacustrine deposits respectively which possibly represent provenance drainages from 4 different directionsBack to article page
