Miocene–Pliocene planktonic foraminiferal biostratigraphy of the Pearl River Mouth Basin, northern South China Sea
The present study deals with the planktonic foraminiferal biostratigraphy of the Miocene–Pliocene sequence of three petroleum exploration wells (BY7-1-1, KP6-1-1 and KP9-1-1) in the Pearl River Mouth Basin (PRMB). In general, the three wells contain a fairly well-preserved, abundant foraminiferal fa...
