Hydrogeochemical Characteristics of the Haiyuan-Liupanshan Seismic Belt at the Northeastern Edge of the Tibet Plateau
Published 2022-01-01“…The higher concentrations of Ca2+ + Mg2+ and HCO3- were found in Group 2, which is located in the southeast of the HLFZ and may be attributed to carbonate weathering and the recharge of karst fissure water from ordovician dolomite and limestone. Contamination of groundwater in HLFZ is severe, with 78.6% of the sites classified as grade V, which means they cannot be used for drinking water or agriculture. …”

CO<sub>2</sub> Sequestration in a Carbonate Saline Aquifer: An Investigation into the Roles of Natural Fractures and Well Placement
Published 2025-01-01“…The geochemical interactions between the injected CO<sub>2</sub> and reservoir fluids and minerals reduce the free and trapped CO<sub>2</sub> quantities by dissolving calcite and precipitating dolomite. Furthermore, natural fractures impact the CO<sub>2</sub> quantities during early times only when the fractures cross the top layers. …”
