摘　　要：系统研究了延怀盆地上地壳热流体的温度、水化学、气体化学与同位素化学特征 ,确定热水成因与大气降水渗入有关 ,并计算了热储温度与水循环深度 ,认为热水活动对中小地震活动有一定的控制作用并影响断裂活动强度。In this paper, some characters of temperature, hydro-chemistry, gas-chemistry and isotope chemistry of thermal fluids in upper crust of the Yanqing-Huailai basin are studied. The genesis of atmospheric water permeating of thermal fluids is determined. The temperature of thermal reservoir and circulation depth of thermal fluids are calculated. And their relationships with seismic and fault activity are discussed.

关 键 词：延怀盆地 地壳流体 地震活动 断裂活动 热流体 循环深度
