Taking for example the salt rhythms of the Qianjiang Formation in the Qianjiang Sag of the Jianghan Basin (which is a typical Paleogene saline lacustrine basin in eastern China), through a detailed study on cores, the authors have determined for the first time the Ⅳ-order salt rhythm based on Ⅰ-,Ⅱ-and Ⅲ-order salt rhythms which were determined previously and got to know that the sedimentary process following the sequence of desalinizing→salinizing and crystallization of salt minerals from halite rock→(mud-bearing) glauberite rock→dolomite-bearing mudstone (mud-bearing doloston)→mudstone→doloston→glauberite rock→halite rock. The authors also analyzed the Ⅳ-order salt rhythm and the correspondence between its sedimentary records and the fluctuation of the palaeosalinity of waters and the short-scale (0.05~1.0 ka duration) change of dry-moist palaeoclimate.
本文以我国东部独具特色的古近纪古盐湖盆地-江汉盆地的潜江凹陷潜江组盐韵律为例,通过对王平1、王云10-6、王80-2等3口井连续取心段的精细研究,在前人划分Ⅰ、Ⅱ、Ⅲ级盐韵律的基础上,首次划分出组成含盐层系基础韵律单元-Ⅳ级盐韵律,弄清了它的沉积过程基本遵循从石盐岩→钙芒硝岩→含白云石泥岩→泥岩→白云岩→钙芒硝岩→石盐岩的淡化-咸化序列和盐类矿物的析出顺序;解析了Ⅳ级盐韵律及其沉积组合记录与水体古盐度波动和短尺度(0.05~1.0 ka)古气候干湿变化之间的对应关系。
