The main objectives of this study is not only to document the modern benthic foraminiferal assemblages of the Taiwan Strait, but also to examine their distribution in relation to environmental parameters, such as water depth, salinity and TC, TOC, TIC, coarse fraction in sediments. Three benthic foraminiferal biofacies are recognized in the sediments substrate type collected from Taiwan Strait: Type A (relicted sediment) is dominated by Quinqueloculina spp.. Type B (close to Mainland China) is characterised by Textularia spp., Spiroloculina spp., Amphstigina spp., Cibicides spp., Lenticulina spp., Sigmodela spp., Globulina spp., Nummmulites spp., Chilostomella spp., Bulimina spp., Bolivina spp., Brizalina spp. and Eponides spp.. Type C (close to Taiwan Island) is composed by Ammonia spp., Discorbinella spp., Elphidium spp., Nonion spp., Triloculina spp., Asterorotalia spp., Heterolepa spp. and Pararorotalia spp.. Living benthic foraminifera by Rose-Bengle stained form the Taiwan Strait seem not to be related with TOC contents and propotions of coarse grains. Instead, their assemblages are found to be more related to the source of sediment and tidal energy.
