- Abstract:
- In this paper we analyze the hydrochemical composition and the composition of the isotopes of hydrogen and oxygen of 19 water samples collected at 4 observation stations for underground fluid and their neighbouring ponits in the north segement of the Yilan-Yitong Fault in Northeast China,and study the types and genesis of the groundwater in the fault zone.The results indicate that:① The water temperature at these sampling points ranges from 8.5 ℃ to 23.4 ℃.The total dissolved solids(TDS)of the water samples,all of which are low salinity water,ranges from 32 to 568 mg /L.②The water samples can be classified into 10 chemical types,and the water-rock reaction does not reach complete equilibrium.The sample at Tonghe station belongs to “partial equilibrium water” and feautures deep source.③The δD-value ranges from -100.24‰ to -65.46‰,and δ18O from -13.47‰ to -8.53‰,indicating that the recharge source of the samples is mainly atmospheric precipitation.
