Summary: We report semiquantitative geochemical data of four sediment cores from the North Pond area on the western flank of the Mid-Atlantic Ridge at 22°45'N, 46°06'W. Three of the sediment cores, from Holes U1382B, U1383D, and U1384A, were drilled during Integrated Ocean Drilling Program Expedition 336. Core from Hole 1074A (Ocean Drilling Program Leg 174B) was also included in this study. The data show highly variable fluorescence intensities for Ca, Al, Si, Fe, Mn, and K. These variations can be explained by varying proportions and frequencies of foraminiferal sand intercalating with clayey nannofossil ooze. The sand layers show high Ca counts and low counts for all other measured elements. The ooze layers show noticeable counts for K, Al, and Si, which is interpreted as illite clay fraction. In addition, the concentrations of Fe and Mn increase toward the sediment/basement interface in Holes U1382B and Hole 1074A and especially in Hole U1384A, but not in Hole U1383D. The sediment pile at all four drill sites shows slight enrichments in Fe and Mn in the uppermost few meters. Rock debris (millimeter to centimeter sized) is present in Holes U1382B and U1383D and to lesser extent in Hole 1074A, but not in Hole U1384A in the northwesternmost part of the sediment pond. These data provide a cursory assessment of the different sediment lithologies in the North Pond area, in which coupled hydrological-geochemical-microbiological sub- basement experiments are currently being conducted.
