Abstract

End-member (EM) analysis of grain-size distribution data for detrital fractions of IODP Site U1430 core sediments from the South Korea Plateau (East Sea) identified 4 EMs grain-size populations (EM) which represent either Asian dusts (Hwangsa) or volcanic ashes. The two EMs representing volcanic ashes consist of fine and coarse glass shards with various morphologies and constitute 0–82% of the total grain-size distributions. The 33% mixing percentage of volcanic ash EMs seems appropriate for a cut-off value for discrimination of grain-size data influenced by volcanic ash input from those dominated by Hwangsa.

동해 남한국대지 IODP Site U1430 시추 퇴적물 쇄설성 성분의 입도 자료에 대한 구성 성분 분해 결과 황사 입자와 화산재 입자를 대표하는 4개 구성 입도 집단이 구별되었다. 이 중 화산재 입자를 대표하는 2개 구성 입도 집단은 다양한 형태의 세립 및 조립 유리질 샤드들로 이루어져 있으며, 전체 입도 분포에서 0–82% 범위의 비율을 차지하고 있다. 분석된 입도 자료 중 화산재 유입 영향을 받은 자료를 제거하고 황사 입경 변화의 경향을 추출하기 위한 기준으로 화산재 구성 입도 집단 비율 33%가 적정한 것으로 판단된다.
