Summary

Late Palaeozoic coal series are distributed extensively over eastern China. From the late Carboniferous to the Late Permian, coal accumulation migrated from the north to the south (i.e. from high to low latitudes). Thus, the stratigraphic position of the main coal group in the late Palaeozoic profile varied accordingly. The migration of Mesozoic coal accumulation was in a reverse direction relative to that of the late Palaeozoic. From the late Triassic to the early Cretaceous, however, the stratigraphic position of the main coal group in the Mesozoic changed gradually from the south to the north. This south–north migration of coal accumulation occurred under the control of syndepositional activity of a latitudinal tectonic system. On the basis of the geomechanics and systematic sedimentological analysis of coal-bearing sequences, it is suggested that the tectonic systems consist of four main types: latitudinal structures, linear shear structures, meridional structures and epsilon-type structures. These controlled the sedimentation of coal-bearing sequences in east China and their sedimentation features indicate the impact of the tectonic control.
