摘要:
在位于依兰—伊通断裂北段的4个地震流体观测站及其附近地区采集了19个水样,对水样的水化学组分及氢氧同位素组成进行分析,对该地区地下水类型及成因等地球化学特征进行了研究。结果表明:①取样点水温变化为8.5 ℃～23.4 ℃,水样的矿化度为32～568 mg/L,全部为低矿化度水; ②水样分为10种化学类型,水-岩反应均未达到完全平衡; 通河台井水属于部分平衡水,具有深部来源特征; ③δD和δ18O值的分别为-100.24‰～-65.46‰和-13.47‰～-8.53‰,表明所测水样的补给源主要为大气降水。
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.
