| Research Abstract |
The horizon previously interpreted to be Cenomanian/Turonian boundary was not the boundary. We found that the real boundary located at horizon that believed to have been near Coniacian. The horizon was composed of remarkable red beds. Such condition is opposite to the contemporaneous proto-Atlantic and Tethyan oceanic condition. This finding suggests that Southern Pacific has significant importance for elucidating mechanism of OAE2. Cooler deep water formation near this region during OAE2 could explain the red beds formation.
