| 摘 要： | 关中盆地地下热水中氢氧稳定同位素的研究表明：研究区地下热水中氢氧稳定同位素组成变化与当地古气候变化具有良好的对应关系,古气候变化直接影响了地下热水接受补给时的氢氧稳定同位素组成。研究区地下热水的补给为更新世前古代大气降水。大约在8.2～10.2 kaB.P.和18.1～19.2 kaB.P.这两个时间段,可能是由于当时温度较低导致关中盆地地下热水补给偏少;关中盆地地下热水的补给过程受古气候的变化影响呈现非等速补给特征,可能存在一定的古地下水形成期。

| Abstract: | The study of the geothermal water oxygen and hydrogen stable isotope of the Guanzhong Basin we suggest that: The charge of geothermal water oxygen and hydrogen stable isotope content and that of the paleoclimate in Guanzhong Basin show obvious corresponding relationship;the supply of oxygen and hydrogen stable iaotopes of the geothermal water was directly affected by the change of the climate.The geothermal water of the research area was recharged by the ancient precipitation before the pleistocene.The two ... |
