The environmental geological survey on a scale of 1:50 000 in the Puqi Map Sheet (also referred to as the Survey) was carried out by relying on the project titled Environmental Geological Survey on a Scale of 1:50 000 in the City Clusters of the Middle Reaches of the Yangtze River Along Xianning-Yueyang and Nanchang-Huaihua High-speed Railway initiated by the China Geological Survey. The dataset obtained through the Survey (also referred to as the Dataset) was developed by methods such as the hydrogeological survey, karst collapse survey, hydrogeological drilling and water-quality testing and analysis. It consists of the data of 73 spring survey points, test and analystical results of mineral water from 7 water samples and the data from 1 karst collapse point, 7 karst cave points and 10 hydrological boreholes. The detailed contents of these data are as follows:the results of the spring water survey include locations of spring survey points, water quality indices to be tested in the field and the genesis of spring water. The analytical results of mineral water are the ones reaching the requirements of mineral water according to the indoor testing of water samples taken from spring points and hydrological boreholes in the Puqi County Map Sheet. The data of karst collapses mainly include location of karst collapses, features of collapse pits, geological background and the state after collapse. The survey results of karst caves include the location, development features and development and utilization of the caves. The data of boreholes contain the location, diameter and depth of the boreholes. The Dataset will provide an important geological source for the planning and construction of towns, safe utilization of land and the development of high-quality geological resources in Chibi City.
