用岩盐中痕量元素含量作成因评价的原理是将各种不同成因作模型比较。假定大洋中所用的痕量元素的含量从古生代到现代基本不变,那么可以推算出盐类矿床在一定的成因条件下痕量元素含量的范围。如果这样计算的结果与分析出来的痕量元素的含量相一致,这种模型就可能是正确的。Rb 类质同像进入钾盐而代替 K,因而特别适合评价钾盐成因特征。显然,和 Br 配合起来就可能阐述得更加清楚,虽然评价将会变得更 The principle of using the trace element content in rock salt as the cause of evaluation is to compare various causes for the model. Assuming that the content of trace elements used in the ocean is essentially constant from the Paleozoic to the modern, it is possible to deduce the range of trace element contents of salt deposits under certain genetic conditions. If the result of this calculation is consistent with the content of trace elements analyzed, this model may be correct. The Rb analogues enter into the potassium salt in the same way instead of K, making them particularly suitable for characterizing the causal genesis of the potassium salt. Obviously, it may be clearer to work with Br, though the evaluation will be even more pronounced
