Figure F3. Si and Ca expressed as weight percent of the sediment from Site 1218 as a function of depth. The relationship to lithologic units (I = clay, II = nannofossil ooze/chalk, III = radiolarite, IV = nannochalk/dolomite) is also shown. Each point indicates a separate chemical analysis. The line inside the gray box in the bottom right corner of each graph indicates the long-term precision of the analysis (see Table T1, )).
