VIEW SHOWING LAFAYETTE-SUNDERLAND SCARP, SUNDERLAND surface IN THE FOREGROUND, NEAR CHARLOTTE HALL, ST. MARYS COUNTY. maryland geological survey 57 General Stratigrapiiic Kelations. Throughout the Coastal Plain of the Middle Atlantic slope, the Lafay-ette and Columbia deposits rest on the eroded edges of the older forma-tions which are buried beneath them. The materials of which thisyounger mantle is composed have been supplied in great measure by thedestruction of the older beds on which they rest. The appearance ofthese older deposits is frequently so characteristic and striking that it isnot a difficult matter to recognize materials which have been derived fromthem and are now re-worked in a younger formation. As so much de-pends on a clear understanding of the older deposits of this region, theywill be briefly described before proceeding farther. pre-cambrian and older rocks on which the surficial deposits rest are found alongthe eastern border of the Piedmon
