Calcareous biogenic turbidites in the Central Pacific Basin

概要

論文の詳細を見る
The results of collecting piston core data and seismic profiling reveal the distribution of calcareous biogenic turbidites in the Central Pacific Basin. These turbidites originate on the Manihiki Plateau, the Line Islands Ridge, and the Magellan Rise. The sedimentation of turbidites originating on the Magellan Rise and the northern Line Islands Ridge had ceased since the Miocene, out of the high organic productivity zone around the Equator. But the Manihiki Plateau and the southern Line Islands Ridge have been supplying calcareous biogenic turbidites to the eastern Central Pacific Basin.
