Abstract

Wentang Valley Anticline is selected as study area and thermal water resources in this area will be discussed in this paper. Because of the same geological backgrounds, the hydrogeochemical features of the thermal water is similar in this study area, and its hydrochemical type is SO4-Ca. In addition, the thermal water contains multiplicate and sanative microelements and gases, such as Sr, F, Li, B, and Rn, so it is superior iatrical thermal water. The thermal water source is atmosphere precipitation. And its aquifer may be the stratum of Jialingjiang formation in Lower Trias (T1j). Na-K-Mg diagram shows that five water samples fall in the region of immature water. So it can be said that it has low tempertures in the fluid-rock processes and the thermal water maybe mixed. Mineral equilibrium diagram (log(Q/K)-T diagram) indicates that the log(Q/K)-T curve of quartz is closest to saturation line, and the equilibrious temperature is 65~77°C. This temperature is within the reservoir temperature (65~82°C) calculated by quartz geothermometer.

西南温塘谷背斜地热水资源水文地球化学特征

本文选取文塘谷背斜为研究区，对该区的热水资源进行了探讨。由于地质背景相同，研究区热水水文地球化学特征相似，水化学类型为SO4-Ca。此外，该热水含有Sr、F、Li、B、Rn等多种有益健康的微量元素和气体，是优良的医疗热水。热水源为大气降水。其含水层可能为下三叠统(T1j)嘉陵江组地层。Na-K-Mg图显示，5个水样落在未成熟水区域。因此可以说，它在流体-岩石过程中温度较低，热水可能混合在一起。矿物平衡图(log(Q/K)-T图)表明，石英的log(Q/K)-T曲线最接近饱和线，平衡温度为65~77℃。该温度在石英地温计计算的储层温度(65~82℃)范围内。
