The Kasane Hot Spring with discharge temperatures of 43–50 °C is characterized by intermittent bubbling accompanied by white precipitant within its vicinity. The hot spring discharges mainly along Chobe River which meets the Zambezi River at the tip of northwest Botswana. In this study the Curie point depth (CPD) was estimated using the spectral centroid method of aeromagnetic data at Kasane Hot Spring and the surrounding regions. The upward continued aeromagnetic data were analyzed to obtain depths to the bottom (CPD) of the magnetic sources. The CPD values were then used to compute the geothermal gradient, subsurface crustal heat flow including radiogenic heat flow distribution in the region.

According to the obtained results, the depth to the magnetic bottom varies from 6 to 22 km. These depths are comparable to those obtained from recent regional study of the Okavango Rift Zone. The areas with shallow CPDs of demagnetized rocks at depth are located around Kasane Hot Spring, where high heat flow values in the range 70–90 mW/m² were recorded. Moreover, the radiogenic heat production values between 0.50 and 0.60 μWm^-3 within the same region may also provide an extra contribution to the geothermal potential of Kasane Hot Spring. The correlation of estimated shallow CPDs with high geothermal gradient, high heat flows, and radiogenic heat flow values at area within Kasane region indicate possible geothermal resource. The CPDs values obtained may be associated with the seismic events in the region and surroundings. The mean earthquake depth of events that occurred within Kasane and surrounding areas from 1987 to 1991 is 10 km, while the mean Curie Point Depth is approximately 11 km. These seismic events in the area could be responsible for possible thermal accumulation at Kasane Hot Spring, resulting in high heat flow values in the area.

排放温度为43–50°C的Kasane温泉的特征是间歇性冒泡，附近有白色沉淀物。温泉主要沿着乔贝河排放，该河在博茨瓦纳西北端与赞比西河汇合。在这项研究中，居里点深度（CPD）是使用Kasane温泉及其周围地区的航磁数据的谱质心法估算的。分析向上连续的航空磁数据，以获得到磁源底部（CPD）的深度。然后，将CPD值用于计算地热梯度，地下地壳热流，包括该地区的放射源热流分布。

根据获得的结果，到磁性底部的深度从6到22 km不等。这些深度可与从最近的Okavango裂谷带区域研究获得的深度相当。深度深处的去磁岩石CPD较浅的区域位于Kasane温泉附近，记录到的高热流值在70-90 mW / m ²范围内。此外，放射性热生产值0.50和μWm之间0.60 ^-3同一区域内的岩浆也可能为Kasane温泉的地热潜力提供额外的贡献。估计的浅层CPDs与高地热梯度，高热流以及Kasane区域内区域的放射源热流值之间的相关性表明可能存在地热资源。所获得的CPD值可以与该区域和周围的地震事件相关联。1987年至1991年，卡萨内及其周边地区发生的平均地震深度为10 km，居里点深度约为11 km。该地区的这些地震事件可能是造成Kasane温泉可能蓄热的原因，导致该地区的热流值较高。
