碳酸盐岩热储中稀土元素的地球化学行为及其指示意义：以施甸地热系统为例
Geochemical Behavior and Indicative Effect of REEs in Carbonate Geothermal Reservoir: A Case of Shidian Geothermal System
,
施甸中‒低温地热系统是滇‒藏‒川地热带的重要组成部分，强烈的构造运动使该地热系统热储结构复杂，当前对其地热水地球化学过程研究程度很低.通过分析施甸地热水中稀土元素（REEs）的地球化学行为，本文旨在揭示碳酸盐岩热储内的主导性水文地球化学过程.结果表明，施甸地热水大部分富集LREEs，显示其对围岩REEs特征的继承.地热水也表现出Ce、Eu和Y异常，其中Ce负异常因继承碳酸盐岩Ce负异常或保留地热水古氧化环境特征而形成，Eu正异常源于地热水对长石类矿物的溶解，Y正异常则是地热水运移过程中其中的Ho受碳酸盐矿物优先吸附造成.PHREEQC计算表明施甸地热水中REEs的主要形态为LnCO3 +和Ln（CO3）2 ‒，在同一水样中，LnCO3 +含量随原子系数增加依次递减，而Ln（CO3）2 -则依次递增.此外，地热水中还存在少量Ln3+、LnF2+、LnHCO3 2+和LnSO4 +，其含量均随原子系数增加依次减小，受地热水pH和F-、HCO3 -、SO4 2-含量共同控制.REEs分析可为地热水地球化学过程研究提供重要证据.
Shidian medium-low temperature geothermal system, which has a complicated reservoir structure due to the intense tectonic movement, is a critical part of the Yunnan–Sichuan-Tibet geothermal Province (YST) with few studies focusing on it. The goal of this research is to study the geochemical behavior of the rare earth elements (REEs) in the Shidian geothermal system in order to reveal the dominant hydrogeochemical processes in the carbonate geothermal reservoir. The results in this study show that most of the geothermal fluids are rich in LREEs, indicating an inheritance of REEs feature from the host rocks. The geothermal fluids also have Cerium (Ce), Europium (Eu) and Yttrium (Y) anomalies. Among which, the negative Ce anomalies are probably the result of interaction between geothermal water and carbonate rock or an indicator of paleo-oxic conditions. The positive Eu anomalies are ascribed to the dissolution of feldspar minerals, while the positive Y anomalies are caused by the preferential adsorption of Ho on carbonates during the transport of geothermal fluids. The calculation by PHREEQC shows that the dominant species of REEs in geothermal fluid are LnCO3 + and Ln(CO3)2 ‒. The content of LnCO3 + decreases with the increasing atomic number, in contrast, Ln(CO3)2 ‒ increases with the increasing atomic number. In addition, there are still some Ln3+, LnF2+, LnHCO3 2+ and LnSO4 + species with small amount in the geothermal fluid, which are controlled by the pH of water as well as F‒, HCO3 ‒, and SO4 2‒ content. REEs can provide important evidence for studying the hydrogeochemical processes in a geothermal system.
