71561,远高于同期海水和下沟组玄武岩,略高于代表早白垩世湖水锶同位素组成的藻灰岩,但低于基底壳源硅铝质岩,反映热流体不可能为单纯的湖水或幔源岩浆水;其中直接化学结晶沉淀的纹层状泥微晶热水沉积岩锶同位素比值变化范围较小,可代表均一化的热卤水池流体锶同位素组成特征;指示不同喷流口位置的"水爆角砾岩"锶同位素组成变化较大,但同一位置的热水角砾与胶结物锶同位素组成基本一致,说明两者应属于具相同成因意义的同期热水喷流沉积产物;综合青西凹陷下沟组湖相热水沉积岩锶同位素地球化学特征,初步推测早白垩世湖底热流体可能为富集硅铝质基底岩石高放射成因Sr的深循环下渗湖水与少量上升幔源岩浆水构成的混合热流体,可为青西凹陷早白垩世湖底热流体性质的确定以及热流体循环动力学模型和热水沉积模式的建立奠定基础。
