Research on Sequence Stratigraphy of Late Mesozoic in Basin Groups of East Heilongjiang Province
详细信息   
摘要

Based on the data analysis of outcrop, core, logging, seismic profile, palaeophyte and geochemistry, the sequence stratigraphic frameworks of Late Mesozoic in Sanjiang, Boli, Jixi and Hulin basins are established in this paper. The comparison and the analysis of evolution characteristics among the basins are conducted in terms of the palaeontological change and the sedimentary cycle caused by tectonic movements, ingression events, volcanic events. Two megasequences, five supersequences and twenty sequences are identified. The tectonic subsidence controls the megasequence, supersequence development and the distribution of relict sequences within basin. Sea level change dominates the sequence evolution.
