摘要
本文研究山西省太原市东山盆地边缘的地下水中的氚含量和用其测定地下水的年龄。本区属黄土丘陵台地孔隙水区中的黄土长梁中深度贫水区,水位埋深40—80m(在河沟、冲沟内含水层是河卵石、大砾石,水位埋深2—10m)。各个水井中的地下水年龄分别为23、14、25、41和53a。
The tritium content is measured in underground water from the basin side-band of the East-Mountain Region of Taiyuan, Shanxi Province, and hence the age, i. e. resident time, of underground water is estimated. The region belongs to deep water-poor zone in a long loess ridge situated in a loess hill plateau. The level of underground water is 40-80 m deep hidden. In the runway and the scouring channel the aqueous bed is of river pebble and cobble, with a level of 2-10m in depth. The age of underground water from different wells were determined to be 23a, 14a, 25a, 41a and 53a respectively.
