Abstract

The application of electromagnetic in hydrogeological investigation in Việt Nam has obtained some possitive results in some areas, where demonstrate favourable topographic conditions such as in Khe Lặc hot-mineral water spring, Đại Thành Commune, Tiên Yên District, Quảng Ninh Province. The geophysical survey in Khe Lặc allowed us to delineate an anomaly zone related to broken reservoir rock. The hydrogeological drilling indicated that hot-mineral water aquifer was encountered at 38.5 m deep. This paper introduces an integrated geophysical method in investigation and evaluation of hot-mineral water in Khe Lặc, Quảng Ninh Province.
