The abundance of Al (sub 2) O (sub 3) and TiO (sub 2) in bulk sediments, acid-leached sediments and acid leachate of two types of sediment from the South China Sea were measured by ICP-AES and ICP-MS. Results indicate that there exists a significant non-detrital aluminum (excess Al) component in bulk sediments from the South China Sea. Calculations indicate that excess Al accounts for about 20-70 percent of the total amount of aluminum in bulk sediments. Therefore, using Al abundance to estimate the abundance of terrestrial material in marine sediments, which has generally been used in previous studies, may overestimate the abundance of terrestrial material. However, there is little authigenic Ti enrichment in sediments from the South China Sea, and Ti is the best proxy for the abundance of terrestrial material.
