The chemical compositions of waters from the upper basin of the Ctalamochita River draining the Córdoba Pampean Ranges were analyzed to determine the chemical signature related to different forcings, geochemical processes, and solutes sources. The catchment has four sub-basins: Santa Rosa River, Grande River, Quillinzo River and De Los Sauces River. Most of the riverine chemical compositions are dominated by the HCO₃⁻–Ca²⁺-type to Ca²⁺–Na⁺–Mg²⁺. The specific conductivity is higher in the Santa Rosa and De Los Sauces rivers (347.59 and 409.00 μS/cm, respectively) than in the Grande and Quillinzo rivers (125.56 and 87.54 μS/cm, respectively). Mineral hydrolysis of andesine and oligoclase and the dissolution of calco-magnesian limestone, are the main dissolved solids contributors to the river waters. Higher contribution of bicarbonate ions is associated to those sub-basin having quarry mining activity. Saturation indexes show that the Santa Rosa and De Los Sauces rivers are saturated with calcite, dolomite, and talc.

分析了从克拉塔莫奇塔河上游流域科尔多瓦庞贝山山脉排水的水的化学组成，以确定与不同强迫，地球化学过程和溶质来源有关的化学特征。流域有四个子流域：圣罗莎河，格兰德河，基林佐河和德洛斯酱河。大部分河流化学成分由HCO ₃ ^-- Ca 2 ⁺ -型占Ca ²⁺ -Na ⁺ -Mg ²⁺占主导地位。在圣罗莎河和德洛斯酱河中的比电导率更高（分别为347.59和409.00μS/ cm），比在格兰德河和基林佐河中的比电导率更高（分别为125.56和87.54μS/ cm）。矿物质水解的山药和寡糖和钙镁石灰石的溶解，是造成河水溶解的主要固体。碳酸氢根离子的较高贡献与那些具有采石场开采活动的次流域有关。饱和度指数表明，圣罗莎河和德洛斯酱河中的方解石，白云石和滑石粉已饱和。
