地球化学是研究盐类沉积和钾盐矿床的重要手段。但过去的工作往往带有一定的局限性,多偏重于盐类沉积物本身微量元素的研究,对组成含盐系中的泥质岩地层缺乏应有的注意。欲更好地了解Q凹陷含盐系的形成条件,古盐湖发展史及成钾规律,就必须对含盐系沉积进行比较全面的地球化学研究。 Geochemistry is an important means of studying salt deposits and potash deposits. However, the past work tends to have some limitations, and more emphasis on the trace elements of salt sediment itself, the lack of attention to the composition of salt-bearing argillaceous rocks. For a better understanding of the formation conditions of salt sag in Q depression, the history of ancient salt lake development and the law of potassium production, it is necessary to conduct a comparatively comprehensive geochemical study of salt-bearing sediments.
