STRATIGRAPHIC POLLEN ANALYSIS OF ELEVEN CORES NEAR EDGEWOOD, MARYLAND

Several cores were extracted from sediments of the peninsula between the Bush and Gunpowder Rivers near Edgewood Maryland. Samples were extracted at irregular intervals from eleven of these cores and submitted for environmental pollen analysis in order to assist in determining ages for strata underlying the peninsula. Accurate determination of biostratigraphic ages are difficult, at best, and require extensive, close-interval sampling to determine changes in frequency and the appearance and disappearance of pollen types from the record. The samples extracted from these cores represent intervals no closer than eleven feet apart, and generally dozens to nearly a hundred feet apart. Given the irregular and widespread samples, only coarse interpretations of the sediments below the peninsular are possible
