摘要
利用海水蒸发实验资料,在双对数图上,可以建立Cl-、Na+、Mg2+、SO、K+、Ca2+、HCO-3、Sr2+、B3+、Li+、Rb+Cs+、I-含量及矿化度与Br-含量的关系曲线,称为海水蒸发轨迹线。它们可以用来帮助判断沉积盆地地下卤水的起源、分析沉积盆地蒸发岩卤水在后来的成岩环境中是否发生过成岩反应。
Ionic concentrations and TDS of seawater change systematically during evaporative concentration of seawater. Log-log plots of Cl-,Na+,Mg2+,SO,K+,Ca2+,HCO-3,Sr2+,B3+,Li+, Rb+,Cs+,I- and TDS versus Br- of evaporated seawater can be established by using experimental data, and are referred to as seawater evaporation trajectories. They may provide clues to identification of the origin of subsurface brines in sedimentary basins, and explain whether diagenetic reactions of evaporite brines with subsequent diagenetic environments in sedimentary basins have occurred.
