查询词典 salt formation

Based on the correlation of the Guadalupian and Lopingian conodont zones of the Salt Range, Pakistan with those of South China, the Amb Formation and the lower part of the Wargal Formation in the Salt Range, Pakistan are Late Guadalupian in age. The Guadalupian/Lopingian boundary is in the lower part of the Wargal Formation, and the Wuchi-apingian/Changhsingian boundary is in the lower part of the Chhidru Formation. The Permian/Triassic boundary is in the Kathwai Member of the Mianwali Formation.

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。
