莱洲湾沿岸浅层地下卤水蒸发成因新依据

Latest Origin Basis of Underground Bittern Evaporation in Costal Areas of Laizhouwan Gulf

摘要:

山东莱洲湾沿岸是我国重要的天然卤水矿产地,分布广、浓度高、储量大,关于其成因通过近几十年来的研究可归纳为蒸发浓缩生卤和冰冻生卤2种,但其依据尚不够丰富。该文从海水冰冻实验与蒸发实验所经历的路径中,Na/Cl与Ca/Mg随浓缩倍数的变化趋势来分析卤水的成因,认为其应属蒸发浓缩生卤。

Abstract:

Costal areas in Laizhouwan gulf in Shandong province is an important natural bittern source in China.In these areas,bittern resource distributes widely with high density and big reserve.Through study in decades,origin of natural bittern can be divided into two types: one is evaporation and concentration,the other is deep freezing.On the basis of sea water evaporating and freezing experiment,combining with the result of variation trend of Na/Cl and Ca/Mg ratios,it is regarded that natural bittern in Laizhouw...
