Abstract: Twenty planktonic foraminiferal datum planes and eleven benthonic foraminiferal events useful for intraregional and international correlation have been recognised in the shallow marine Neogene sediments of Western Taiwan.
Planktonic foraminiferal datum planes are based on first occurrences (thirteen datums), last occurrences (five datums) and on changes in the coiling direction of Pulleniatinu (two datums). Benthonic foraminiferal events comprise first occurrences (six events), concentration zones (four events) and last occurrences (one event).
Correlation of these datum planes and events with standard Neogene foraminiferal zones indicates that in the Foothills Region of Western Taiwan, the Early-Middle Miocene boundary occurs within the Nanchuang Formation, the Miocene-Pliocene boundary in the uppermost part of the Kuantashan Sandstone and the Pliocene-Pleistocene boundary in the middle part of the Cholan Formation.
