Abstract

Abstract

Langjiu geothermal field in Tibet is located in the northeast margin of Himalaya-Gangdisê plate. In this region, tectonics, magma activity and metamorphism are intensive, and the cap rocks of the geothermal reservoir are damaged during the tectonic and fluvial processes, which lead to the cold water mixing with the thermal water. Carbonate rocks are widely distributed in this region, and incompletely cooled granites become heat sources of the geothermal field. Equilibrium temperature of the thermal reservoirs is between191.11and213.85. The surface water in the geothermal field is bicarbonate-calcium type. Thermal spring’s water is chlorine-bicarbonate type in terms of anionic and kalium-sodium type in terms of cationic. The thermal springs TDS is 2000～2300 mg/L with the value of Na+/Cl-greater than 1, and the evolution degree of thermal springs is between mature water and immature water, so water-rock interaction has not reached equilibrium. From saturation indexes of some typical hydrothermal minerals are greater than 0, we can infer that hydrothermal alteration has much contribution to chemical composition of thermal springs. The partial pressure of carbon dioxide is greater than 2000 Pa, which forms great grads difference comparing to the regional background and will lead to massive carbon dioxide degassing.
