| 摘 要： | 陕西渭北地处鄂尔多斯南缘,分布大面积的古生代碳酸盐岩,由于东西部所处地质背景不同,岩溶地区含水介质特征以及对应的地下水赋存、运移、循环特性存在极大的差异性.通过对东、西部岩溶含水岩组的结构组合特征、地质构造特征以及地球化学背景特征的深入对比,分析了对岩溶作用的影响,揭示了造成两地岩溶地下水赋存特性差异性的内在原因.

| Abstract: | In Weibei area, Shaanxi Province,Paleozoic carbonic rocks are extensively distributed, which serve as an important aquifer in this area. As the geological background in the east is quite different from that in the west, many aspects of karst groundwater cha racteristics in these two parts, such as distribution,pemeability,scale of groundwater flow system and groundwater regime, show sharp contrast. Based on a comparison of the lithologic association of Ordovician carbonic rock,geological structural evolution and geoche mistry between the east part and the west part of Weibei area, this paper reveals the intrinsic reason responsible for the diffe rence in karst groundwater characteristics between the east part and the west part of Weibei area. |
