摘要
依据氢、氧同位素地质学方法及其分布规律性 ,可将四川盆地广泛分布的卤水划分出四种类型 :大气水渗入淋滤型、海相沉积型、海相沉积与大气降水叠加型、海相沉积与岩浆水叠加型卤水。用氢、氧同位素法研究水成因 ,分类明确 ,标志明显 ,有确定的成因涵义 ,应用效果良好 ,可弥补水文、地球化学法的不足。
On the basis of hydrogen and oxygen isotope compositions, brines in Sichuan Basin may be divided into 4 types: meteoric water leaching type, marine sedimentary type, meteoric water leaching-marine sedimentary superimposed type and marine sedimentary-magmatic water superimposed type. Origin of brines may be determined by hydrogen and oxygen compositions which can remedy defects of hydrogeological and geochemical methods.
