erosion surface

The freeform N[O.sub.2.sup.-] concentration on the erosion surface of the cement paste specimens (depth 0 mm from the erosion surface) was the lowest, far lower than the N[O.sub.2.sup.-] concentration inside the cement paste specimens, reached highest value at a distance of 10 mm from the erosion surface, and achieved a steady state of 80mm.

Stream power ([OMEGA]; [W.sup.-1] [m.sup.-2]) is the energy of runoff per unit surface area, some of which may be available to remove and transport aggregates from the erosion surface downslope.

Erosion surfaces must be considered when superimposing the thickness of the overlying layer--if the overlying layer is faulted, the same displacement must be reflected in the erosion surface (Fig.

This procedure allowed the creation of digital models for Neogene sediment and erosion surface (buried under Neogene sediments) capacity allocation.

An erosion surface separates the underlying wave-dominated facies succession from overlying tidal facies successions in each regressive-transgressive cycle.

The lithology changes marked by erosion surface could be associated with reworking and winnowing of the preexisting deposits as a result of prevailing tide, wave, or storm action [24].

The erosion surface has no local age constraint, since correlative lacustrine deposits have not been found within the Maestrat sector.

African erosion surface; a continental-scale synthesis of geomorphology, tectonics, and environmental change over the past 180 million years.

In the Slave Province, orogenesis had ceased by 2580 Ma (massive late granite event) and the erosion surface cooled to ca.

"The fact that it had an erosion surface means it was exposed to the atmosphere and to weathering," says Buick.
