摘要
本文探讨康定本格措景区热矿水的水热活动变化规律，热储特征和水化学组分的形成及变化。初步分析表明。水热活动的强度由南往北逐渐减弱，主要表现在水温降低，泉日沉淀物减少，ＰＨ值由碱性变为弱酸性和水质组分呈相应的规律变化。结合泉口沉淀物，用Ｓ１Ｏ２温标法估算出热储温度达１６５℃—１８０℃。通过论证水化学组成的形成和变化，对水热活动强度的差异作出解释。在此基础上，确定了康定木格措景区独立的热矿系统，并提出其成因模式。
ased on hydrogeochemical principle and method,the paper discusses the essentialcharacteristics of the thermal mineral water, including: 1) hydrogeology activity pattern; 2)thermal reservoir feature and 3)formation and change of hydrochemical compostition. It is indicated from the preliminary analysis that the intensity of the hydrothermal activity progressively decrease from south to north,obviously appearing as the water temperature drop,thespring sedimentdecrease,PH value change from alkaline to neutrality and the relevant waterquality change. Combined with the spring sediment,the thermal reservior temperature is estimated at 165-180℃ using SiO2 temperature scale. The authors prove the formation andchange of the hydrocheAncal composition to explain the difference of the hydrothermal activity and its genesis model is presented in Mugecuo Scenic Spot.
