AEOLIAN ORIGIN OF THE RED EARTH TORMATION IN JIUJIANG CITY OF JIANGXI PROVINCE, CHINA :EVIDENCE FROM GRAIN-SIZE ANALYSIS
-
Abstract
The Red Earth Formation in the middle-lower Yangtze River is an important pedostratigraphical unit in southern China.This formation is among the best geological records of Quaternary environment that bear information of climate changes for the subtropical zone of China.The study on the origin of this formation is the basis for further investigation of the paleoclimatic information.In this study, grain-size was analyzed on the samples from Jiujiang section at Jiujiang city of Jiangxi Province, and the result was compared with that of the typical Quaternary eolian deposit, as well as the lacustrine and fluvial sediments.Grain-size distribution was determined with a Malvern Mastersizer 2000 particle analyzer with a precision less than 1 %.The analysis on grain-size indicates that the Xiashu loess and vermiculated red soil (VRS)in Jiujiang section consist of uniform fine particles.The particles display a bimodal distribution, with grain-size fraction of 5 ~ 50 μm dominantly, and > 63μm in a small part.The distribution is essentially similar to that in the Xifeng loess samples, but differ from the multimodal patterns of the lacustrine and fluvial deposits.The Xiashu loess and VRS are also similar to the Xifeng lo ess samples in grain-size parameter.The mean grain-sizes of the Xiashu loess and VRS are about 6.4 ~ 6.8ϕ (9.0 ~ 11.8 μm)and 7.1 ~ 7.2ϕ (6.8 ~ 7.3 μm)respectively, somewhat finer than those of the Xifeng loess samples.The Xiashu loess, VRS and Xifeng loess have a smaller mean square deviation value than the fluvial samples, indicating a much better sorting and relatively stable depositional dynamics.The Xiashu loess, VRS and Xifeng loess samples show a positive skewness, but the fluvial samples a negative one.The lacustrine samples also show a positive, but obviously larger skewness.In kurtosis value, the Xiashu loess and VRS samples are close to the Xifeng loess, and the fluvial sediments are obviously smaller than the lacustrine samples.All these indicate that the Red Earth Formation in Jiujiang area have the same origin as the Quaternary loess in northern China.
