The authors describe the characteristics of unconformities, which are discontinuities in a pile of sedimentary rocks that have resulted from temporary nondeposition of sediment, erosion of previously deposited sediment, changes in the rate of sedimentation, changes in the composition of sediment being deposited, or combinations of those factors.

In Canada, and other glaciated regions, they are interbedded with glacial deposits and have been most useful in determining periods of sedimentary nondeposition, and interpreting interglacial climates.
The formation of ripple marks and lithification of deposits were followed by a period of nondeposition and erosion of the basin floor, at least in the areas surrounding the central part of the shoal where mounds and reefs started to develop.
351 to clarify it is the only rule for nondeposition discovery from nonparties, Park said, and Rule 1.
The stage is missing in some westernmost sections (Ohesaare core in southwestern Estonia) or has restricted thickness (about 5 m in the Kaliningrad Region; Laskov & Paskevicius 1989) due to pre-Porkuni submarine erosion or nondeposition.
351 is the exclusive means to obtain nondeposition discovery from nonparties and permits the court to resolve objections to such discovery.
It occurs as an aberration to prevailing environmental conditions, in this case, of general nondeposition (or very slow deposition) normally characteristic of floodplain depositional settings.
Contact relationships indicate that this unconformity is the result of nondeposition of the Upper Ordovician sediments associated with the Queenston Shale and the Big Hill Dolomite due to the presence of a topographic high.
Situated to the right of the cores in Figure 5 is a column illustrating periods of deposition and nondeposition (Ross and Ross, 1988).
The local character of nondeposition and the variable extent of deposition breaks suggest a tectonic origin of the upheaval, most probably induced by the beginning of the collision of the Laurentia and Baltica continents (Nestor & Einasto 1997).
The local character of nondeposition and changeable extent of the deposition break were most probably of tectonic nature, induced by the beginning of the collision of the Laurentia and Baltica cratons (Nestor & Einasto 1997).
