苏北灌南地下水补给源同位素地球化学分析
Isotope geochemistry analysis of groundwater recharge source in Guannan, Northern Jiangsu Province
摘要
Abstract
In order to find the reason that water quality of Guannan Tanggou winery area is better than that of others, and trace the source of high-quality groundwater to optimize the utilization of groundwater , the groundwater in Guannan area was studied by the methods of hydrogen-oxygen isotope and geochemical analysis , probing the relationship between hydrogen-oxygen isotope and main anion and cation existing in the river water , well water and precipitation .The results show that , the hydrogen-oxygen isotopic relationship of deep confined water in Guannan area is obviously different from that of diving water and surface water .The strontium and metasilicate are rich in the confined water , while they are not available in the diving water and surface water .It is inferred that the deep confined groundwater used by Tanggou winery should come from the exogenous source .The recharge source area of concealed volcano basalt groundwater might be located in the Southeastern Tibetan Plateau and Yunnan Guizhou Plateau area.There might be water conducting channel of the exogenous water in the cenozoic concealed volcanic basalt in Tanggou town .The pore-type volcanic basalt is in accordance with the rock characteristics of water flowing channel .关键词
