Abstract
Magnetotelluric measurements from the Sabalan geothermal field in northwestern Iran have provided clear indications of geothermal reservoirs. This study aimed to identify shallow and deeper conductivity anomalies associated with geothermal systems in the Sabalan area. The magnetotelluric method is widely used for exploring subsurface resources, as it is suitable for detecting subsurface anomalies at significant depths. Based on modeling results, thick conductive layer was found near the surface of the Moil Valley area, where two reservoirs are embedded. The main reservoir, located on the west side of Sabalan volcano, extends from the south and southwest of Sabalan peak to the west and Moil valley. The dimensions of this reservoir are almost twice as large as the estimated volume obtained from previous studies. Another smaller reservoir is located to the north of the peak.
伊朗西北部萨巴兰地热田的磁电测量提供了明确的地热储层迹象。这项研究旨在确定与萨巴兰地区地热系统相关的浅层和深层传导异常。磁电探测法适用于探测较大深度的地下异常，因此被广泛用于勘探地下资源。根据建模结果，在 Moil Valley 地区地表附近发现了厚厚的导电层，其中蕴藏着两个储层。主储层位于萨巴兰火山西侧，从萨巴兰峰的南部和西南部一直延伸到西部和莫伊河谷。该水库的面积几乎是之前研究估计容量的两倍。另一个较小的水库位于山峰北部。
