   Объект исследования. Балапурский разлом, расположенный в центральной части Кашмирского бассейна в СЗ Гималаях.

   Материалы и методы

   Материалы и методы. Данные общей магнитной интенсивности региона были получены с помощью наземных магнитных съемок, проведенных протонными прецизионными магнетометрами с интервалом 15 м, проводились также исследования магнитных ограничений и инверсий Балапурского разлома.

   Результаты

   Результаты. Установленная средняя магнитная интенсивность усредняется до 97.7 нТл с минимумом 45.8 и максимумом 140.9 нТл. Минимумы в диапазоне от 45.8 до 55.8 нТл получены в сетчатом профиле Балапурского разлома. Кроме того, индекс чувствительности, связанный с отказом, был зарегистрирован от 0.0035 до 0.0015 SI, а наблюдаемые и прогнозируемые значения отклика находились в диапазоне от 67.1 до 87.7 и от 67.4 до 86.6 нТл соответственно.

   Выводы

   Выводы. Предполагается, что Балапурский разлом в Центральном Кашмире вызвал высокую подповерхностную гидравлическую активность и, следовательно, низкие магнитные аномалии. Выявлена область мощных минимумов, связанных с разломом, а также наличие структур, связанных с основной частью Балапурского разлома.

   Research subject

   Research subject. Subsurface investigations of the Balapur Fault at central Kashmir Basin, NW Himalaya through groundmagnetic surveys and data interpretations.

   Materials and methods

   Materials and methods. The total magnetic intensity data was obtained using ground magnetic surveys carried out by proton precession magnetometers at 15 m spacing. The magnetic constraints and inversions of the Balapur fault in the central Kashmir basin of NW Himalaya were analyzed.

   Results

   Results. The total magnetic intensity was found averaging at 97.7 with 45.8 nT as magnetic minima and 140.9 nT as magnetic maxima. The minima’s ranging from 45.8 and 55.8 nT in the gridded profile are inferred at the Balapur fault. Further, the fault-related susceptibility index was recorded from 0.0035 SI to 0.0015 SI, and the observed and predicted response values were found ranging between 67.1 to 87.7 and 67.4 to 86.6 nT respectively.

   Conclusion

   Conclusion. The study suggests that the Balapur fault in the central Kashmir has produced high subsurface hydraulic activities and, therefore, evident low magnetic anomalies. The analysis reveals a thick minima region related to the fault and also indicated the presence of associated structures with the main Balapur fault segment.
