| Zusammenfassung |
| The Xianshuihe Fault with frequent earthquakes activities is the regional deep fault in
China. The Moxi Fault is the southern part of the Xianshuihe Fault, where the strong
activities of geothermal water could bring abundant information of deep crust. In this
article, some typical geothermal springs were collected along the Moxi fault from
Kangding to Shimian. Using the the Na-K-Mg equilibrium diagram, it explains the
state of water-rock equilibrium, and estimates the reservoir temperature basing
appropriate geothermometers. Basing on the relationship between the enthalpy
and chlorine concentration of geothermal water, it analyze the mixing progress
of thermal water with shallow groundwater. Moreover, the responses of variation
of geothermal water to the solid tides are considered to study the hydrothermal
activities of this fault. The Guanding in Kangding are considered as the center of the
geothermal system, and the hydrothermal activities decrease southward extending.
Geothermal water maybe is heated by the deep heat source of the Himalayan granites,
while the springs in the south area perform the mixture with thermal water in the
sub-reservoir of the Permian crystalline limestone. It improves the research of hydrothermal
activities in the Moxi Fault, meanwhile using the variation of geothermal water maybe
become a important method to study the environment of deep earth in the future. |
