J. Lake Sci.2001,13(3):211-219. DOI:10.18307/20010303 Fresh waters contained ⁸⁷ Sr/ ⁸⁶ Sr information are related to the st rontium isotopic compositions of different rock types which they flowed across.The ratios of Sr/Ca in lake are usually a proxy of salini ty, which can reflect the variation in levels of lake.So, the Sr geochemistry of shells from basin sedimentary can be used to derive a record of the different resources of waters inf low to the basin, and of the changes of water in basin.A study on example of the 28th bed of Xiaodukou sect ion, Nihewan basin, implies that the st rontium geochemistry of shell is a desirble method of palaeohydrological restoration, and further indicates it would be a good future matching with carbon and oxygen isotopes and other trace element geochemisty.
