Abstract: Clay mineral compositions of 35 samples in core I8 recovered from the West Philippine Basin were analyzed by X-ray diffraction (XRD) technique. The results show that the clay mineral assemblages in core I8 consist dominantly of illite (40%), with a lesser abundance of smectite (28%) and chlorite (20%), as well as a low amount of kaolinite (12%), and illite has good crystallinity. The source analysis of clay minerals indicate that the high contents of illite may come from the input of Asian dust, while smectite may be contributed by the nearby ocean bottom volcanoes, and weathering product from Luzon may play the most important role in providing chlorite and kaolinite.
