An eleven-year monitoring (1987/88–1999) of chemical composition of Na-HCO₃ thermal water from the wells Sob-1 and Sob-2 has shown long- and short-time scale changes occurring as a result of mixed character of abstracted thermal water and overexploitation of the wells. Constantly reoccurring changes of dynamic pressure induced the inflow of variable proportions of water from the most productive aquifer Thermal I and from lower-permeability aquifers in the underlying Lendava Formation which contain abundant CO₂. The chloride ions originate from formation waters in the Lendava Formation, and for Thermal I, a local natural background is 80–85 mg/L. The fluoride ions mainly originate from waters in the Lendava Formation but do not correlate entirely with the chloride ions. It is assumed their abundance is largely controlled by interaction of CO₂-rich waters with detritial marine carbonates and clay minerals. Temporal variations of concentrations of the bromide and iodide ions in thermal water from the Sob-1 largely correlate with variation of the chloride ions and indicate that the Lendava Formation is their major source. By overexploitation, some low-permeability aquifers in the Lendava Formation have been activated along with leakage from clayey lenses rich in organic matter and coal in the Mura Formation. The sources rich in the bromide and iodide, and iodide and chloride ions have been also recognized in the Sob-2 well at high pumping rate that amounted to 8.7 L/sec.

东北穆拉盆地Sob-1和Sob-2井中温（46-52°C）热水中卤离子（F-，Cl-，Br-，I-）的时间变化斯洛文尼亚

对Sob-1和Sob-2井中Na-HCO ₃热水的化学成分进行了为期11年的监测（1987 / 88–1999），结果表明，由于水的混合特性，长期和短期尺度发生变化。提取热水和井的过度开采。动压的不断变化促使最有生产力的含水层热力I和底层Lendava地层的渗透率较低的含水层（其中含有大量的CO _2）流入不同比例的水。。氯离子来自伦达瓦组的地层水，对于热力I，局部自然本底为80-85 mg / L。氟离子主要来自伦达瓦组的水，但与氯离子并不完全相关。假定它们的丰度很大程度上受CO ₂相互作用的控制富含有害海洋碳酸盐和粘土矿物的水域。来自Sob-1的热水中的溴离子和碘离子浓度的时间变化与氯离子的变化密切相关，表明Lendava形成是其主要来源。通过过度开采，伦达瓦组的一些低渗透含水层被激活，同时穆拉组的富含有机质和煤的黏性晶状体泄漏。在Sob-2井中还以8.7升/秒的高抽速发现了富含溴化物和碘化物以及碘化物和氯离子的来源。
