Description :
The upland planation surface in the Piedmont of central New Jersey consists of summit flats, as much as 130 km2 in area, that truncate bedding and structure in diabase, basalt, sandstone, mudstone and gneiss. A key question in this region revolves around the origin of the flat upland erosion surfaces that are common in the Piedmont. Three alternatives are proposed. The goal of this paper is to test these alternatives by integrating stratigraphic, geomorphic and cosmogenic Be 10 data to determine the exposure age and erosional history of an upland planation surface in the New Jersey Piedmont.
