地下浓缩卤水与“高山深盆”成盐环境

Relationship between underground concentrated brine and the saline environment of “high mountains and deep basins”

在长期研究青海柴达木盆地现代钾盐矿床和云南兰坪-思茅盆地中新生代钾盐矿床形成原因的基础上,袁见齐教授于1983年提出了“高山深盆”的成盐理论。本文进一步提出该模型可分为“深盆深水”和“深盆浅水”两种类型。前者以邻近海水为主要补给,后者除海水之外,明显渗杂有富含钾、镁、钙的变质地下浓缩卤水,其中富钾卤水对“高山深盆”环境下钾盐矿床的形成意义不言而喻。但目前最大的困难是,我们还不能像研究海水蒸发实验那样,完全解释清楚这种地下浓缩卤水的形成机理,希望有更多的学者对此开展研究。

On the basis of long-term study on the formation of the modern potash deposits in Qaidam basin of Qinghai province and the Meso-Cenozoic potash deposits in Lanping-Simao basin of Yunnan province,professor Yuan Jianqi put forward the salt formation theory of"High mountains and deep basins"in 1983.In this paper the author proposes that the model can be divided into two types:of“Deep basin deep water“and”Deep basin shallow water”.The former is mainly supplemented by nearby seawater,but the latter,in addition to the sea water,was obviously infiltrated with metamorphic underground concentrated brine rich in of K,Mg and Ca.The significance of underground brine rich in potassium to the formation of potassium in“high mountains and deep basins”is self-evident.However,the biggest difficulty at present is that we cannot fully explain the formation mechanism of this underground concentrated brine,as we have done in the study of seawater evaporation experiments.
