摘要
为探讨四川盆地卤水中钾元素的来源,提出了卤水中钾元素来源之一是原始沉积水溶滤绿豆岩中的钾元素的可能性。并将峨眉山龙门洞绿豆岩作为岩石样品,通过模拟实验,将相同的岩石样品装配在不同盐度的浸出液中,通过盐度、温度、时间的不同,得出峨眉山绿豆岩中钾的浸出率并将浸出率进行比对。结果表明,绿豆岩中的钾可以被浸出,进而证明了四川盆地卤水中钾元素的一部分来源是原始卤水溶滤绿豆岩,丰富了卤水中富钾的成因,绿豆岩中钾元素的析出,与浸出液的盐度、温度及时间呈正相关。
To analyse the source of potassium element in the brine of Sichuan basin, a possible point of view that potassium element is come from green - bean rock was proposed. A simulation experiment was designed for validation this view. Through the experiment it prove that the view is correct. The result is rich of the genetic feature of potassium element in the brine. Meanwhile, it is confirmed that the precipitation of potassium element is positive correlation with salinity temperature and time of precipitation solution.
