The Quantitative Analysis of Grain Size Parameters between Lacustrine Deposits and Eolian Deposits in the Middle Area of Shandong Province
摘要
Abstract
Field work on eolian sections and lacustrine deposits was systematically carried out in the middle area of Shandong Province. Grain size was conducted by measuring the deposits of Longqiao in Pingyin area and Dongping Lake. The results showed that there are certain difference among Median, Mode, Minimum, Maximum and Percentile valves. Meanwhile, grain size was tested by Mann-Whitney U. Mann-Whitney U is 8678, Z is - 1.270, P which is less than 0.05 is 0.02. The results showed that they have significant variation. Finally, mean grain size was examined by Independent-Sample T Test. F is 34.757, P which is less than 0.05 is 0.032. The variance of grain size is not equal is - 3.597, df is 150. 77, P which is less than 0.05 is 0.029. This further reveals there are obvious difference between them.关键词
