摘要
根据绵竹三箭水 S1井相关地质区域内各水体的氢、氧同位素组成和放射性同位素氚浓度 ,结合该区的地质背景 ,利用同位素示踪手段 ,基本确定该井温泉地下水的成因为大气降水渗入补给主体含水层补给源在西北部 170 0 m左右的“彭灌杂岩”高山区一带、补给量相对稳定 ,水温不会有大波动 ,有远期开发价值。
Based on the hydrogen and oxygen isotope compositions and radioactive isotope-tritium concentration of the water body of S1 well and its related geological background in Mianzhu,we could determine the contributing factor of thermal spring by using isotope tracer technique.S1 well is mainly caused by meteoric water recharging andthe recharge resource of the main aquifer is in the north-west 'Pengguan complex' with an altitude of 1 700 metre or so.The amount of recharge is steady and the temperature is not fluctuated.So the S1 well have the value of long-term exploitation.
