| Abstract | Basing on the characteristics of geo-tectonical setting, the geologists assume that the geothermal potential of the North Eastern Vietnam territory is at the fourth position among six geothermal areas of Vietnam. There are 21 hot springs in the study area with the surface temperatures from 30.5oC to 71oC. The chemistry of thermal fluids shows that these 21 hot springs are mostly bicarbonate. The results of geothermometer calculation show the deep temperatures of the hot spring from 80oC to 164oC. The ƒÔD and ƒÔ18O plot reveals that the origins of thermal fluids are meteoric. The results of U, Th, K radioactive elements are calculated and showing that the heat sources of these hot waters are not coming from radioactive decay. |
