Electron micrographs of sand grains from southern Piedmont saprolites, temperate and polar glacial deposits, and the St. Peter Sandstone are presented. Sand-grain surface features of saprolite grains are described for the first time and from these some concept of the initial surface of a quartz sand grain is obtained. Micrographs of the sand grains from glacial deposits whose erosional history ...
–Carbon bound in gibbsite, collected from a residual weathering profile developed on a Paleozoic granite in the Georgia Piedmont, was examined for its C content and found to be geologically young. The study site, located at the Panola Mountain Research Watershed, has developed a granite–saprolite–soil regolith in which C-gibbsite model ages deep within the profile (C-horizon) average about 8000...
