Abstract:

The stratigraphic units in terrestrial basins commonly reveal some recurrent rules during sedimentary evolution, which characterize progressive evolution of sedimentary facies (lithofacies) associations, architecture, packing types, and paleontological assembles, corresponding to the potential deposit of economic coal, oil shale, and evaporite. We practically distinguished the varieties of stratigraphic units and bearing economic resource deposit during filling process from the Fushun basin, Liaoning Province, the Tongbai basin, Henan Province, and the Greater Green River basin, US via the illustrative names of coal, oil shale and evaporite-bearing stratigraphic units. Moreover, of which sedimentary evolution is controlled by integrated tectonic and climate. Tectonic and climate control the potential accumulation of terrestrial basins and eventual sediment plus water inflow into terrestrial basins, changing the basin filling status among over-compensation, balance-compensation, and under-compensation, eventually causing the alteration of lithological associations, sedimentary architecture and paleontological assembles of different stratigraphic units, which can reasonably interpret potential deposit of coal, oil shale and evaporite. Furthermore, different tectonic and climate factors in various basins may result in the absent of coal, oil shale or evaporite.
