Abstract

This paper estimates the deep heating temperature of the mineral waters of the Essentuki field by ionic geothermometers. The water is extracted from four productive aquifers (Danian–Selandian, Cenomanian–Maastrichtian, Aptian–Lower Albian, and Tithonian–Valanginian). The study shows that the most adequate deep temperatures, from 64 to 97°C, are provided by a SiO₂ geothermometer; the Na–K geothermometer overestimates and the Mg–Li and chalcedony geothermometers underestimate this temperature. The water penetration depth is assessed at 1.2–1.8 km for the Danian–Selandian, Cenomanian–Maastrichtian, and Aptian–Lower Albian aquifers and at more than 2 km for the Tithonian–Valanginian aquifer.

估算高加索矿泉水地区埃森图基温泉内循环矿泉水的真实地下温度

摘要本文通过离子地温计估算了 Essentuki 水田矿泉水的深层加热温度。矿泉水取自四个富含矿物质的含水层（Danian-Selandian、Cenomanian-Maastrichtian、Aptian-Lower Albian 和 Tithonian-Valanginian）。研究表明，二氧化硅地温仪能提供 64 至 97 摄氏度的最适当深层温度；钾镁地温仪高估了这一温度，而镁锂地温仪和玉髓地温仪则低估了这一温度。据评估，达尼安-塞兰安、塞诺曼安-马斯特里赫特安和中古安-下阿尔比安含水层的水渗透深度为 1.2-1.8 千米，提托尼安-瓦朗基安含水层的水渗透深度超过 2 千米。
