CORRESPONDENCE ANALYSIS OF SIZE-ANALYSISDATA FROM CORE Ch5, CHANGJIANGRIVER DELTA
长江三角洲Ch5孔粒度资料的对应分析

Size-analysis data of 30 sediment samples collected from core Ch 5 Changjiang River Delta were statistically analysed by means of correspondence analysis method. Result of the analysis shows: there are three types of hydrodynamic deposit environments through core Ch5, which are similar to those delineated by using transitional size-analysis method. This paper also suggests that correspondence analysis is a better multivariate analysis for size analysis.
