[Abstract]:Recently, the project of "investigation of Hydrogeologic Environment and Geology in the Upper reaches of Xiangjiang River", which was undertaken by the Institute of Karst Geology of the Chinese Academy of Geological Sciences, has achieved remarkable results. First, hydrogeological conditions and groundwater control factors in the working area were identified. Ten underground rivers and 22 karst springs are investigated. The distribution of karst groundwater is controlled by regional faults, regional synclines and stratigraphic lithology. The syncline is Yuanjia syncline and sand and stone syncline. The groundwater is mostly developed in Devonian and Carboniferous strata. The lithology of the syncline is medium thick limestone and white.
