gradational

Both upper and lower contacts with other plains units are gradational.

While finding them generally valid, she stressed the gradational character of the transitions between the regions.

The contact between the two is gradational.

The contact with the underlying Harrell Formation is generally gradational.

Their bases are sharp, but the tops are gradational.

The outer boundary of this unit is gradational with the (younger) smooth plains that occur in the same region.

Gradational boundaries at top and bottom.

Within the hazard zones, relative hazard is gradational, decreasing away from the location of potential vents.

Both of here shoulders are coupled with elements of the background, superimposed, gradational and transparent to varying degrees.

Ranks are assigned based on subjective dissimilarity, and do not fully reflect the gradational nature of variation within nature.

Silicification zone, often gradational with background silica-albite metasomatism.

The shale tongues typically have sharp basal contacts and gradational upper contacts.

The Redonda has gradational eastward transition into the upper Cooper Canyon Formation.

The thickness of the lithosphere itself shows considerable variety and the boundary with the underlying asthenospere is gradational and difficult to define precisely.

The boundaries between facies (and corresponding areas on the temperature v. pressure graph), are wide, because they are gradational and approximate.

The contacts between members of the Dox Formation are gradational and are based mainly on topographic expression, the sedimentary depositional environment, and color changes.

The change in topographic expression, color, and the facies change, from quartz arenite, to mudstone and fine-grained arkose - is gradational.

Contacts between intercrater plains and intermediate plains units that occur outside mapped craters and basins are gradational and uncertain.

The unit appears to be gradational laterally eastward with plains and terra material, undivided, and vertically with intermediate plains material.

The top of the Tunbridge Wells Sand Formation is well defined in the southwest of East Sussex but is gradational elsewhere.

The lower contact of the Dox Formation with the underlying Shinumo Quartzite appears to be gradational and is marked by a change in topographic expression and color.

The gradational contact between the Shinumo Quartzite and Dox Formation above indicates a shift from deposition in coastal deltas - to fluvial deposition by a large river system.

In the eastern part of the Grand Canyon, the contact between the Hatakai Shale with underlying Bass Formation is typically gradational over an interval of a meter or so.

Manipulation for photo restoration or enhancement (adjusting colors / contrast / white balance (i.e. gradational retouching), sharpness, removing elements or visible flaws on skin or materials, ...)
