δD values of escaped H2 from hot springs at the Tengchong Rehai geothermal area and its origin

  • Zhiguan Shangguan
  • Weiguo Huo


Here we give the · values of escaped H2 from hot springs at the Tengchong Rehai and adjacent regions, and deal with a genetic correlation between the increment H2 in escaped gases from middle-shallow reservoirs and the H2S, CH4 derived from deep sources. Isotopic compositions of H2 indicate that the generation of increment H2 may be related to recent strong activity of N-W trending fault at the Rehai area. Trace monitoring the H2 release could be significant in order to keep watch on present activity ofthat fault.
