- Abstract:
-
On the basis of the heat reservoir temperature and the circulation depth of the hot springs evaluated by the predecessor's through hydrogen and oxygen stable isotopic composition, helium isotopic composition and silicon dioxide content of the water of the hot springs in the Northern Margin Fault Zone of Qinling, and using a mathematical model of vertical liquid movement affected by the geothermal field, we deduce a relation between permeability of the Fault Zone and circulation depth of the hot spring water. We apply the multiple seismic-parameters to analyzing the seismicity of Qinling Fault according to seismic data of regional network from 1970 to 2008, and analyze the distribution of historical moderate-strong earthquakes from 781 BC to 2008 AD. And we research the correlation between the permeability and seismicity of different segments in the Fault Zone. Finally, we explain the permeability conditions of the Northern Margin Fault Zone of Qinling.
