1、It rests on erosional disconformity.

2、Benefits and hazards of subground erosional geomorphy of loess tunnels

3、Such truncation is evidence of an erosional hiatus.

4、Such cuestas may be either erosional escarpments or fault scarps.

5、The erosional surface dissected by such valleys may subsequently become an unconformity in the stratigraphic sequence.

6、This erosional basin was closed and evolved into a depositional basin during middle Late Pleistocene.

7、Cumulate plagioclase appears abruptly at the base of the F unit, which rests on an erosional disconformity.

8、Xenoliths are found at numerous horizons, and locally there is evidence of scour and other erosional features.

9、The multicycle evolutional history, paleostructural configurations. structural characteristics and major erosional unconformities control the generation and distribution of oil and gas reservoirs.

10、The collapse propagates itself by blocking and diverting the underground streams, so that hydraulic gradients become steeper and the solutional and erosional capacities are enhanced.

11、Its sedimentary structure includes large-scale inclined beddings, trough cross-beddings, low-angle cross-beddings as well as an erosional basal surface.

12、Further check result on the basis of the heat-balance calculation and experiments proved that erosional fatigue is the main reason that causes the leakage in the evaporate cooler.

13、The rapid crustal uplift in the Pleistocene and physical weathering and erosion, especially the erosional process of the flood in the mountains, are the direct causes for the formation of the gorges.
