| 摘要: |
| 水动力条件是盐湖成盐成矿的必要条件之一.利用研究区各类水体的理化参数（pH、氧化还原电位、电导率和总溶解性固体）、水化学特征、元素比值等参数识别尕斯库勒盐湖成盐元素的来源及水力迁移作用.结果表明：尕斯库勒盐湖成盐元素主要来源于蚀源区岩石风化，其中冰川融水、硅酸盐风化、碳酸盐风化和蒸发盐风化分别占0.04%、0.15%、63.89%和35.92%，在祁漫塔格山前一带，受到深部补给作用.高山区到平原区，水动力条件总体上逐渐降低；而在垂向上随着深度的增大含水层I~Ⅱ之间水动力条件逐渐减弱，含水层Ⅲ~V之间水动力条件变充足.河流与溢出带水体之间存在局部水流系统，与平原区含水层之间存在区域水流系统.水动力条件和水力联系对元素的迁移和富集具有明显的相关性，二者控制着元素的迁移速度以及元素在空间上的富集规律并影响着水化学类型. |

| Abstract: |
| Hydrodynamic is one of the most important conditions during the process of salt metallogenic. This study utilized the parameters such as pH, oxidation-reduction potential, electric conductivity, total dissolved solid, hydrochemical characters, elements rate to identify the material source and hydraulic migration in the Gas Hure salt lake. The result revealed that material source is due to rock weathering of erosion area, with the contribution of glacier melt water, silicate weathering, carbonate weathering and evaporation salt weathering as 0.04%, 0.15%, 63.89% and 35.92%, respectively. The piedmont of Qiman Tage mountain is recharged from deep aquifer. From the mountain to the plains the hydrodynamic is gradually decreased; for the hydrodynamic in vertical profile,from the aquifer I to aquifer Ⅱ it is decreased, while increased from the aquifer Ⅲ to aquifer Ⅴ. The river water and overflow water has local water exchange and both of them have regional flow system. Hydrodynamic condition and hydraulic connection has obvious correlation to the migration and enrichment of elements and controls the speed and the migration of elements enrichment regularity of elements in space, and even affects the hydrochemical types. |
