Paleosurface

In geology and geomorphology a paleosurface is a surface made by erosion of considerable antiquity. Paleosurfaces might be flat or uneven in some cases having considerable relief. In geomorphology the erosive nature of paleosurfaces tend to be stressed. In geology paleosurfaces are at times considered part of the stratigraphic record corresponding to unconformities. Flat and large paleosurfaces —that is planation surfaces— have higher potential to be preserved than small and irregular surfaces and are thus the most studied kind of paleosurfaces.
