Аннотация

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

   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. 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. 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.
