抄録: A field survey documented the lithostratigraphy and sampled for biostratigraphic, paleomagnetic and isotopic analyses of sedimentary sections to the east of Dannevirke, Southern Hawke's Bay, New Zealand. The studied marine sequence was deposited in the forearc basin along the Hikurangi Trench from the late Miocene to the latest Pliocene. The marine sequence is divided into Moastone, Mapiri, Mangatoro, Pukerua, Te Aute, Okarae, Kumeroa, and Mangatarata Formations in ascending order. The sedimentary sequence is cut into spindle shape blocks by faults with right lateral movements. Oxygen and carbon isotopes of foraminiferal tests indicate that the sedimentary environment was shallow, with relatively higher near-bottom than surface primary production. A distinct tec-tonic event occurred in the latest Pliocene, 2.2 Ma, reflected in an angular unconformity at the base of the Kumeroa Formation and deformation of the formation immediately after its deposition. The event rearranged the forearc basin and terminated the deposition within it. The event was associated with volcanic activity.
