Description:
The preliminary results of a comprehensive study of clay minerals (〈2 µm) are presented for the upper 2 m.y. of sediments from Ocean Drilling Program Leg 184 Site 1146 from the northern margin of the South China Sea, close to the Pearl River mouth. More than 500 samples were analyzed, and four main mineral species are present: smectite, illite, chlorite, and kaolinite. On a general basis, illite + chlorite and smectite display anti-correlated behavior in relation to changes in the proportion of primary to secondary minerals in the sediment. Low-frequency and high-frequency changes are observed in the smectite/(illite + chlorite) ratio.
