氢氧稳定同位素习性及其在四川盆地卤水成因研究中的应用

四川盆地地下卤水分布广泛，类型繁多。通过氢、氧同位素地质学的方法研究盆地卤水成因，将其划分为淋滤型、海源沉积型、混合型、具岩浆水特征的海源沉积型等四种类型。在四川盆地使用氢、氧稳定同位素进行地下卤水分类，可获确定的成因涵义，且分类明确，标志明显，取得了较好的效果

RESEARCH ON ORIGINATION OF SALINE WATER IN SICHUAN BASIN WITH REFERENCE TO HYDREN AND OXYGEN ISOTOPIC BEHAVIOURS

Saline waters are circulating about beneath the Sichuan basin, with different genetic types. With reference to H and O stable isotopic composition, the author grouped the saline waters into four genetic types: leached, seawater fed, magma related and mixed. As shown by the practice, the division will offer clear cut definition, distinct marks and genetic constraints for each type if according to H and O stable isotopic behavours, the brines of the Sichuan basin are type divided. Such a practice with the basin has made better results.
