마이오세 후기 안다만해에서 생물기원 오팔 함량의 폭감에 대한 논의 = Discussion on the Late Miocene Biogenic Opal Crash in the Andaman Sea

다국어 초록 (Multilingual Abstract)

Biogenic opal crash at about 6.7 Ma was identified at both IODP Site U1447 and NGHP Site 17 in the Andaman Sea. The different biogenic opal content and general variation pattern between two sites may be attributed to the different concentration of analytical reagent and sedimentation rate estimated by the different chronological approaches. Nevertheless, this study suggests that the biogenic opal crash in the Andaman Sea is closely related to the restriction of Indonesian Throughflow and to the decreasing strength of Indian summer monsoon during the late Miocene, both of which resulted in the reduction of nutrient supply.
