| 摘 要： | 成矿过程中金属元素的溶解性是地球化学研究的一个重要领域.探索开放、非平衡状态下地质流体中金属元素的溶解性有助于了解矿床成因和成矿机制.成矿体系的温度、压力和成矿流体的盐度、pH值、fH2O、fHCl及络合物配体(F-、Cl-、S2-等)的浓度等均对成矿金属元素的溶解性有着重要影响.对于成矿体系状态、近年来国内外关于成矿金属元素溶解性的研究及人工合成流体包裹体、傅里叶红外光谱、显微激光拉曼光谱、电感耦合等离子体质谱法、扩展X射线吸收精细结构和紫外-可见光谱技术在金属元素溶解性方面的应用进行了阐述；认为热液金刚石压腔与拉曼光谱仪联合进行的高温谱学技术可以为实现成矿模拟实验和进行谱学原位测量进而解决成矿流体中金属元素的溶解性问题提供一条新思路,具有广阔的前景.

| Abstract: | The solubility of metal in ore-forming fluid geochemistry is an important area.The exploration of an open,non-equilibrium state geological fluid solubility of metals in ore-forming process will help to understand the metallogenic mechanism and form of metal migration and factors on the solubility of metal.Mineralization system temperature,pressure and salinity of ore fluids,pH and fH2O,fHCl magnitude and complex ligands(F-,Cl-,S2-,etc.) content,etc would have an important impact on the solubility of metal.This paper describes the forming system of the state,the solubility of ore-forming metals and the application of synthetic fluid inclusions and Raman FT-IR,laser Raman micro spectrometer,inductively coupled Plasma-mass spectrometry(ICP-MS),X-ray adsorption fine structure(EXAFS) and UV-visible NIR technique on the study of solubility at home and abroad in recent years.The high-temperature spectroscopy on the connection of hydrothermal diamond anvil cell(HDAC) and Raman spectroscopy will provide a new idea for the realization of ore for spectral simulation and in situ measurements,and help solve the solubility of metal in ore-forming fluids,and thus has broad application prospects. |
