Deep Continental Scientific Drilling Engineering Project in Songliao Basin: progress in Earth Science research
Published 2018-06-01“…Currently, the following preliminary scientific research progress has been made: 4334.81 m in situ core data has been obtained; the centimeter-level high-resolution characterization of the most complete and continuous Cretaceous continental strata ever unearthed has been completed, and the standard profile of continental strata has been initially established; the unconventional natural gas resources and basin-type hot dry rocks in the deep Songliao Basin were found to have good prospects for exploration and development; the climatic evolutionary history of the Cretaceous continental strata was rebuilt for the first time, covering hundreds of thousands to millions of years, and the major events of Cretaceous climate fluctuations have been discovered; all these reveal strong evidence for the subduction and aggregation of paleo-ocean plates, providing a theoretical basis for the re-recognition of the genesis of the Songliao Basin and for deep earth oil and gas exploration. …”

The Evolution and Sources of Major Ions in Hot Springs in the Triassic Carbonates of Chongqing, China
Published 2020-04-01“…Factor analysis and ion ratio relationships show that Ca<sup>2+</sup> and SO<sub>4</sub><sup>2−</sup> are mainly derived from the dissolution of gypsum and anhydrite within the geothermal reservoir, with some addition of SO<sub>4</sub><sup>2−</sup> from coal-bearing cap rocks. The main source of HCO<sub>3</sub><sup>−</sup>, is in the dissolution of dolomite and CO<sub>2</sub> that also promotes the incongruent dissolution of albite and K-feldspar, adding Na<sup>+</sup> and K<sup>+</sup> to the groundwater. …”
