摘要
通过对华北平原沧州地区第四纪地下水中宇宙成因核素3 6Cl进行的测定 ,其浅层咸水的3 6Cl Cl值为5 7× 10 - 1 5,证实了该区浅层地下水的盐化成因主要是蒸发浓缩所造成。该区深层地下水中大气成因的3 6Cl所占的份额为 33%～ 30 %,系由上覆咸水下移所致。
Chlorine-36 was determined to trace the origin of Quaternary groundwater of Cangzhou area in Hebei plain.The raitio of 36Cl/Cl is 57×10 -15.The results indicated that saline groundwater at shallow near the Cangzhou area is of origin of the continental salinization.The calculations of deep groundwater assume that about 33%-30% of ground water is meteoric origin, indicating that deep fresh water has mixed with the upper saline water.And the deep groundwater can be regarded as transportation downward of the upper saline water.
