Characteristics of Grain Size. Element Geochemistry and Their Environmental Implications of Hard Clay from Suzhou Area. China

作者：Xuan Xiaona,Zhao Qing

摘要：Based on systematical analysis of grain size and element geochemistry of the hard clay samples from Suzhou Area, China, it is found that the hard clay consists essentially of silty grains of 4 to 63 ptm in size? with an average grain diameter of 5. 2 to 7. 1 Ф and also a small amount of fraction with diagram higher than 63 /nm. It tends to display the bimodal patterns of distribution.
