| 摘 要： | 渭北东、西部岩溶水的化学特征各不相同。这种不同，是由于含水介质的差异而造成的。东部岩溶水的含水介质为中奥陶统的滨海相、潮间泻湖相与广海陆棚相的灰岩夹膏盐地层，水化学类型为HCO3·SO4、SO4·HCO3或SO·4HCO3·Cl型，矿化度一般为1g／L左右；西部岩溶水的含水介质以中、上奥陶统浅海相或浅海深海相的灰岩、白云质灰岩、粒状灰岩为主，水化学类型为单一的HCO3型，矿化度一般为0．5g／L左右。

| Abstract: | Because of the difference of aquifer, the chemical feature of karst water in the east part is not same as that in the west part in'north Weinan, Shaanxi The aquifer of karst water in east part is limestone and gypsum with littoral, intertidal lagoon and open sea shelf facies in middle ordovician, the hydrochemical types include HCO3. SO4type, SO4 - HCO3type, or SO4. HCO3. Cl type, the degree of mineralization is about 1g/L, the aquifer of karst water in west part is mainly limestone, dolmitic limestone and grainstone with shallow-sea or shal-low-sea and deep sea facies, in middle-upper hydrochemical type is only HCO3 type, the de-gree of mineralization is about 0. 5 g/L. |
