Outline of Final Research Achievements

The Cretaceou/Paleogene (K/Pg) boundary Event, occurred at 66 million years ago, is one of the most famous extinction events in the earth’s history, and is characterized by dying out dinosaur and ammonites. Our study discovered a continuous succession from the uppermost Cretaceous to the basal part of Paleocene in the Nemuro Group at Kawaruppu section based on planktic foraminifers, calcareous nannofossils and carbon isotope stratigraphy. We also identified prominent positive peak of iridium and platinum contents at the K/Pg boundary strata in the studied sequence. The K/Pg boundary at Kawaruppu section is 1 m thick strata which is considered to be the thickest K/Pg boundary muddy strata in the world. High resolution study of this strata has a potential to clarify detailed faunal and environmental change in the western North Pacific region during the K/Pg boundary Event.

Academic Significance and Societal Importance of the Research Achievements

本研究により,明瞭な白亜紀/古第三紀境界が東アジアで初めて発見された.また,今回発見された境界層は古環境変動の解析に適した泥質の堆積物の中では世界でも最も厚いため,同イベント発生時における北西太平洋の古環境変動を高解像度で明らかにすることができる.
