摘要

在卡鲁裂缝含水层中寻找有生产力的井眼从来都不是一件容易的事。东开普省新构造带裂缝性卡鲁含水层可作为地下水勘探的目标。Polile Tshisa温泉位于受新构造运动影响的地震构造区。温泉是断裂带深部地下水循环的标志，因此也是新构造运动的标志。利用磁学和电磁学方法对温泉进行表征可以帮助推断有利于地下水潜力的构造的存在。Polile Tshisa温泉以断层、裂缝和白云岩岩脉为特征。所有这些构造使温泉成为地下水勘探的一个很好的研究案例。

Magnetic and Electromagnetic Signatures around Polile Tshisa Hot Spring in the Northern Neotectonic Belt in the Eastern Cape Province, South Africa

Finding productive boreholes in the Karoo fractured aquifers has never been an easy task. Fractured Karoo aquifers in the neotectonic zones in the Eastern Cape Province can be targeted for groundwater exploration. The Polile Tshisa hot spring is located in a seismo-tectonic region beset by neotectonics. Hot springs are indicative of circulation of groundwater at great depths along fault zones, and accordingly of neotectonics. The characterisation of hot springs by means of magnetic and electromagnetic methods can help infer the occurrence of structures which are favourable for groundwater potential. The Polile Tshisa hot spring is characterised by faults, fractures, and dolerite dykes. All these structures make the hot spring a good case study for groundwater exploration.
