Significant parts of the clay layer immediately below the Pittsburgh coal rest on an unconformity, that is, an old eroded surface.

It was reoccupied in the 13th and 14th centuries, when clay layers were laid down to provide a firm foundation for the timber buildings.

"Clay layers" are dry clay (V) which also form part of the grain volume.

In winter, melting is at a minimum, meaning that only fine material is supplied to the lake, causing thin clay layers.

The term "perched" refers to ground water accumulating above a low-permeability unit or strata, such as a clay layer.

Reduction of groundwater levels in the Mississippi floodplain during the 1950s caused the mound to dry out, damaging the clay layers within.

The amphipod lives in seeps formed when water rises through the substrate and is then trapped just under the ground surface by a clay layer.

The clay particles contain polyvalent cations which give the faces of clay layers a net negative charge.

The boundary is represented by a 1-cm thick tonstein clay layer which has been found to contain anomalously high concentrations of iridium.

Flow paths are created even in tight silt and clay layers, which allow escape and capture of the vaporized contaminants.

The relatively impermeable clay layers trap ground water in the "confined aquifer" which, if tapped, supplies artesian wells.
